[@sondreformolindheim7108]

Was about to comment this. Haha. Great video. Let me know how your workaround is if you have 1) A Atomos Ninja attached to the camera through HDMI Signal - AND 2) An external monitor through SDI. Whenever I change the EI on the Fx6, the Ninja + External SDI Monitor change brightness based of the EI. I know I can apply a LUT to the Atomos Ninja, but my SDI Monitor can't have LUTS Applied. So; As far as I'm aware, there's no way to turn off the LUT (EI) Signal on one of those signals. Correct me if I'm wrong. Highly appreciate your video. :)

[@JimMakosCom]

The clearest sign that exposure isn't changing, is by enabling auto-ND and watching eND NOT changing when changing EI value! Great video for a new FX6 user, thanks!

[@grayscale31]

The best explanation of Cine EI mode is think of it as 1. Yes, you first expose your image as you normally do without changing EI at all while keeping at base ISO 2. Now think of different scenario of brighter or darker scene where whilst exposing (again) as you normally would but you have in back of mind that I want to retain the highlights or shadows by adjusting in post but you are not sure if the image exposed well enough to retain those in post, this is where you just crank up/down EI temporarily and just check on screen if you have those informations or not to be able to do in post. Also that amount of EI up/down can be stored in metadata so that one can achieve exact that in post while grading. Hope this helps.

[@petrub27]

[@affogatoplays]

It helped a lot thank you

[@TheSteveKinney]

[@wildwestadventures3583]

Is this essentially like previewing a lut

[@BarefootMediaTV]

so basically, the different cine ei's are just luts? Thats it? the iso is always one of the two base ISOs and whatever Cine EI you change it to is like changing the LUT you are looking at?

[@RonaldKasper]

Yes, exactly!

[@LorenzoHines.]

This!!! Yes, I was trying to think.. which wasn’t mentioned.. having the lut on is the most important small detail to get the “final” look in terms of using Cine EI. Because you won’t really tell a huge difference if everything is shown in regular SLog without a lut. The lut, on, will show you the corrected image with cine ei, although you’re recording overexposed. That’s what I’m getting from this, but I just didn’t hear was mentioned. That lut, is key. (At least I think lol)

[@RonaldKasper]

@@LorenzoHines. the LUT „on“ makes that you see the exposure lines in the waveform after the LUT was applied. Otherwise it would show the slog3 exposure. And yes, for correcting the exposure with a whitecard like I‘ve shown, this is necessary.

[@shueibdahir]

I finally understand how this works after almost a year of figuring it out. I though an ISO invariant sensor is needed for this but no. This feature can be achieved with a monitor that you can load LUTs into that adjust exposure -3EV to +3EV. Aka exposure correction luts. -1EV on a LUT is like EI400 and -2EV IS EI200. +2EV is EI3200. My 11 year old camera can take advantage of this same thing

[@RonaldKasper]

Yes, that’s basically correct. But with cine EI you don’t need an external monitor for it. If you have a camera that lets you load correction luts on it, it would even work without cine EI directly in camera.

[@silvergullproductions]

Thanks you so much. I’ve watched several videos on CINE EI and they show how to use it, but don’t give a proper understanding of what it actually does. Your video is great, it sums it up perfectly! 🙂👍🎥

[@RonaldKasper]

Thanks a lot, I‘m happy when it was helpful! I have several other videos about image noise or custom mode vs Cine Ei on my channel, maybe you‘re interested in these as well.

[@elliotalderson2479]

Iso doesn’t affect exposure it affects the perception of exposure. The only “iso” that matters is the native iso. Shoot at native iso you can raise it to whatever you want by iso or in your NLE and it will have the same amount of noise. Changing the iso for exposure is a videographers tool to bake in exposure changes not expecting to grade anything. If you are going to color correct the footage where 99% of pros will (including videographers now) changing iso isn’t useful. Shoot at the native and adjust exposure with t-stop,light output & ND like you’re supposed to do. Shutter angle obviously messes with motion blur so kinda locked into that but those are your tools. This just removes iso control forcing you to do what you should have been doing already

[@RonaldKasper]

Yes, all this is automatically fulfilled when you use the cine ei mode

[@StoryPartnersFilms]

Can you tell me if this is correct? You only have 2 Base ISOs that you can choose from in Cine EI. When changing the EI values in your camera you're not actually changing anything with the exposure of your real image file... it only changes how you see the image in your monitor. The reason to adjust your EI values are only for you to see how to adjust the exposure through lighting, ND, or Aperture, So if you want clean shadows you lower your EI value. This darkens the scene in your monitor and you realize you need to bring in more lights for your subject to be properly exposed because everything has gotten darker. Then when you bring this footage into your grading software all looks overexposed. But you'll just bring down the exposure to correctly expose your subject and your shadows will be clean! Is this correct?

[@RonaldKasper]

This is exactly correct. Although the new Davinci Resolve already takes the EI value and sets it in the „RAW“ page of the color tab. So it automatically darkens it for you. Of course you can adjust this darkening to your liking.

[@StoryPartnersFilms]

@@RonaldKasper That's cool!

[@evandomme]

Perfect video to explain Cine Ei! Simple! I know how to use it but it’s this time is so easy to understand in a video. But you could over expose with Cine EI. Exemple : ISO 800 by 2 stops if you want expose a mountain (with snow) to get more dynamic range in highlight 😊

[@RonaldKasper]

Thanks Emmanuel for your comment! And yes, in some situations it could eveb be useful to use a higher EI that ISO, but that's really only in situations that are very bright. Like the mountain-environment with snow you mentioned. But normally you're good to leave EI under the ISO value.

[@JUMADO]

Just getting started with all this and trying to cram as much knowledge in my brain as possible. The video helped me a lot, still I have one question left. When using a greycard in a try to expose correct I would try to line up the waveform with the "dedicated" line - white: 70% grey 40% black 20%. Am I doing this on the SLOG Footage so without EI dropped down or monitor it with "the look I want"? Maybe another example is necessary: I want to overexpose the image for less noise in the final image so I either drop the ND or add more light. My EI is still at 800 - now my footage is overexposed a bit, but when I drop the EI to 400 or another stop lower it looks like I want it too look. Now if I then want to check the exposure and set a greycard as reference would I "adjust" the exposure as needed while looking on the waveforms of the 400 EI look or the 800EI look?

[@RonaldKasper]

You have to expose for the final look, so when you lower the EI to 400, then you expose for white/middle grey at that value, not at the original slog3 values (EI 800). Because the EI400 is what you will see in your finished footage. Davinci Resolve even overtakes the EI value now when you import the footage, so you will exactly see how it looked like with the applied EI value in camera. There’s no need to take the extra step and bring it down in post. And that’s why you need to adjust your values for the final look.

[@legendjxli1266]

@@RonaldKasperMakes sense, thank you very much!

[@Cinedon]

So it's basically a kind of monitoring option that helps you expose properly by giving you control on what would be visible under what lighting situation by giving you the possibility to expose relative to your Native ISO, so that you don't miss what kind of lighting in your scene and exposure that you want?

[@RonaldKasper]

Hi! You can change this in the "monitoring" section of the menu. Set "SDI/HDMI" to Slog3 and set "VF" to "MLUT". That way, the lut is only applied for the internal camera monitor and your EI-values change the monitor exposure. But on the SDI/HDMI outputs, the SLOG3 signal is sent so this exposure doesn't change.

[@prasadchundi]

Thanks for sharing knowledge.. For FX3, i increaes apeture to adjust exposure instead of ND filters while shooting at 12800 iso. Hope thats ok.

[@RonaldKasper]

If you increase the aperture you loose depth of field. Depth of field means that the foreground is sharp and the background isn’t. If that’s ok for your composition, then your method is fine.

[@tiedtkeio]

Thank you! I feel like I ALMOST understand haha. I'm a currently A7S3 user so can't really try this out myself, so does the EI mode kinda "replace" your ISO? Meaning you can't adjust ISO values in EI mode? Where do you pick the recorded EI level? I mean if you lower the EI value shown in the video doesn't that just do the exact same thing as lowering the ISO? This is unless the camera always records 12800 if you like set it in the menu somewhere and changing the EI on the monitor is just an viewing exposure value like you described in the beginning. 😅

[@RonaldKasper]

Hi! No the ISO does not replace the ISO. Like shown in the Video, you only have 2 ISO values available in EI mode. If you set the camera to 12.800 and the EI value to 12.800, you see on the screen exactly what you record. If you lower the EI value to 3.200, then you still record everything in 12.800 ISO but the screen looks darker, like if you have choosen 3.200 ISO. That‘s a nice tool for overexposing a bit to get cleaner shadows, but I explain that exactly in the video.

[@alainmorla8806]

The first part announced as a simplification approach is obviously attractive and makes you want to go further. What I understood is that any modification of the EI does not change the setting of the recording. ? Then cine EI is useful for the purpose of recovering information or details either in the highlights or in the shadows by changing first the exposure, then to modify the appearance of the image of the monitor (cine EI ) by playing on several stops in order to obtain an image in accordance with our initial wishes. Right ? In fact you're offsetting your LUT to see the offset that you'll have to do in post to bring the clip into a normal range. And my question is how can we see, the difference between the two setting ? in any matter, in the metadata but may be as well in Catalyst Browse ?? When I change the EI on my display and then read it on my lap top, it looks the same than the cine EI display on my monitor and not the recording clip ??

[@RonaldKasper]

Yes, you summarized it very well. I don't know exactly what you mean with "how can we see, the difference between the two setting", but I assume you mean how you see it in postproduction. The answer is: You don't. The EI value is not recorded in the footage or shown in any setting of the footage as far as I know. You have to bring it manually down the the correct exposure, there is no automation behind this (not even in catalyst browse).

[@georgiossalon]

If I use a LUT like the Leeming LUT PRO in post, that actually brings the footage, I think two stops down and even use it with the monitor as a custom LUT wouldnt the cine EI be useless?

[@RonaldKasper]

Well if you exactly want to overexpose by two stops then you’re right. But with cine ei you can quickly change the stops of overexposure (1/2 stop, 1 stop, 1 1/2 stop) which could be more convenient than changing the LUTs. Otherwise, the result should be nearly the same if the LUT is good and if you stay in the base ISOs of the camera.

[@georgiossalon]

@@RonaldKasperMuch appreciated my friend :)

[@urba.cinematics]

Hi Ronald, Super video! Still i feel a little confused (probably that's just me) When for instance recording at high base ISO and lowering the EI value, you still need to make sure that on the non EI monitor the scene isn't overexposed? I now understand that you can lower the EI value to preview a 'closer to final product' image, but it's not really clear what the process is to expose the actual recorded image. How many stops can we overexpose, or do we just overexpose and make sure it's not blown out? Would we do this with the internal VND's or through other methods? You probably already explained this in others wors in the video, but this EI concept just totally eludes me... Thanks!

[@RonaldKasper]

I think your thoughts about this are too complex. In my example you see that I recorded the deer and the crocodile with EI 3200, but I still recorded it with ISO 12.800. That means the FX6-screen shows how the image would look like when it was filmed with ISO 3200. On that image (that should be our final result), the white-level would be very dark, if we only bring down the EI but don't do anything else. Since we want our white to have a correct level in the end-footage, we need to brighten the scene or lower the ND. So in your recorded SLOG3 footage you bring up the white level more to 100% as you can see in the last part of the video. So the whole image is recorded much brighter, but this is NEEDED because you want to bring down everything in postproduction so that it looks like what was shown on the screen of the FX6. And then your whites have the needed levels in the endresult, although they were recorded buch brighter. your question of how much you can overexpose is difficult. Depends on the scene. But in my tests, where I brought the white level to 77% on the screen with the s709 LUT, I could easily drop down the EI by two stops. Then I re-exposed and brought up the whitelevel by two stops to again 77%. That means I overexposed by two stops and it was no problem.

[@castmaven]

thank you for this video, I am almost at 100% understanding here. Can I ask why you set the zebra to 77%. This is what is confusing me as many are saying to set at 95, or 94 or 93

[@RonaldKasper]

I am monitoring my signal after the 709 LUT is applied, so these are the recommended values from sony for white values. I found that in this video: www.xdcam-user.com/2020/12/a-guide-the-the-fx6s-cineei-mode/?amp=1

[@castmaven]

@@RonaldKasper thank you very much!

[@LukeMichaelJames]

But if you use an ND filter and use your correction LUTs on the monitor, doesn’t that just do the exact same thing if you only use 800 or 12800 when you shoot?

[@RonaldKasper]

No. With an nd filter you reduce the amount of light hitting the sensor. With EI mode you don’t.

[@TheRobsonStudios]

Super great, thank you. Can I just clarify, shooting on an FX3 for example with SLOG3 and cine EI mode, should you always overexpose at least +2.0? For best colour grade and output? Thanks!

[@RonaldKasper]

It all depends on the scot scene, but if there are no harsh highlights I need to protect, I overexpose by half a stop in the lower base iso. The results are fine without overexposing much. In the higher base iso (12.800) I overexpose about +1.7 otherwise I get too much noise.

[@shutterr514]

Hi Ronald I know I'm late to the party. But for some reason, when Im in cine EI mode, when I lower the ISO on my camera my Shinobi also changes the exposure. As per your video when you brought the cine ei exposure your monitor didn't change. What am I doing wrong?

[@RonaldKasper]

Don’t worry, the party is still going on 😉 When your external monitor changes as well, you have probably set the HDMI output signal to „mLUT“. You can change this in the SDI/HDMI output settings. If you use SLOG there, you are really monitoring the unchanged SLOG3 value that is recorded, like I did it in the video.

[@filmmakingforchange]

When you switch to a lower ei value, your display exposure graph aldo shows lower values. Mine doesnt. Id like to be able to use the graph to expose correctly after having dialed in a lower ei value.

[@RonaldKasper]

You can change what your waveform shows in the monitoring section of the FX6 menu. You can choose between the slog 3 signal and a lut that you can apply to the base signal. Probably you monitor the slog 3 signal which never changes when you lower the EI value.

[@robertaltman222]

I am usually doing shoots in less controlled lighting - my question - is it better for me to still use one of the native ISO's of the sensor and adjust exposure up/down in post - or expose 'properly' in camera by changing my ISO and doing digital noise reduction in Davinci Resolve? I am afraid that either under or over exposing at the native ISO in the Cine EI more will leave me with either blown highlights or lost shadow detail that can never be recovered. At least if the data is there doing noise reduction in post gives you a shot at rescuing the image... Thanks!

[@RonaldKasper]

Using a lower EI value than ISO is the same as overexposing with a mirrorless camera. I wouldn’t say this gives you blown out highlights necessarily, but if you need a lot of dynamic range in your image, it could be of course. I typically stay at the native ISOs and didn’t adjust the cine EI too often in real shooting scenarios. What needs to be said though is, that raising the exposure in post has it‘s limitations especially when you work with dark footage. Because it only adds gain to an already noisy image. Cine ei (which is only a tool for controlled overexposure) can really help in these conditions to get an image you couldn’t create in post.

[@christofferren9057]

I am curious on how to use catalyst browse to how to adjust ISO to get the right exposure in running gun situations. I do not want to manually change the exposure but instead access the metadata. I’m guessing this is possible. Can you make a video on that. Explaining the workflow? I’m guessing we will see a better picture quality doing it this way instead of using flexible ISO in camera. 🤔

[@RonaldKasper]

Hi! No this is not possible, don't confuse LOG with RAW. Only in RAW footage you can change the ISO. Catalyst browse does not allow you to do this with FX6 footage (unless you record it in RAW with an external recorder). What you can change in Catalyst browse is just metadata like flags, title, creator and description of the clip.

[@sunchaserz]

If you are using levels or false colour will the readout be based on the true EI value or the simulated EI value? Also what role do preview LUTs and gamma assist have here when working in Cine EI mode. I'm just starting to move away from PP11!!

[@RonaldKasper]

You can set in the monitoring section of the Fx6 whether you want to send the slog3 footage over HDMI or SDI to your EXTERNAL monitor (which doesn’t change at all when you change the EI value) or the signal with the LUT applied (which changes when you change the EI value). So you can decide what you want to monitor.

[@ekphotography]

I have watched many videos on this but still don't "Get" it. I shoot with an external monitor and check false colors when I am shooting and have a LUT applied which basically does the same thing and shows me what my "end" result will be more or less. What's the difference? Is this just when you are using the cameras monitor and with out a gamma display applied? Otherwise it does not make that much sense to me or it is basically the same thing. I always shoot in my dual base ISO's manually .

[@RonaldKasper]

Since you mentioned LUTS, I'll describe it in other words. Imagine you are on location and want to intentionally shoot a scene a bit brigher, because you want to avoid noise in the shadows. You know that you will bring down the footage in postproduction. What options do you have? You can look at the "too bright" image on your monitor but you don't really know what it will look like after you've brought it down. OR you use a LUT on your external monitor, that is designed to show the footage one stop darker. And that's exactly what you can do with Cine EI as well. It just shows your image 1, 2, 3 stops darker than you actually film it. You could do the same with a lut.

[@ekphotography]

@@RonaldKasper Thanks, I do all that all manually for years and using false colors get's me where I need to.

Hi Ronald, According to what I see in this video Sony FX6 monitor and Ninja monitor have different color balances. Ninja's monitor has yellow/green (warm) cast. Is this bother you? Or we should care less? Or do we have to calibrate Ninja? Thank You

[@RonaldKasper]

Hi! Yes you are right, they differ quite a bit. I don’t care too much about the color shift although a calibration would definitely be a good idea. I‘m a lazy „fix it in post“ guy although I rely more on the big screen to be honest. and it looks pretty good after I‘ve put in in Davinci.

I’m not sure why but in Cine EI on the fx3 when I change the EI it changes the exposure on both the camera monitor and my Ninja V. Any thoughts about this?

[@RonaldKasper]

Yes you can change this in the „Shooting“ settings. At least there it’s on the Fx6. In the menu for „Sdi/Hdmi“ you can choose if you want to show (and monitor) the internal 709 LUT (which I did in my example) or the slog3 signal (which never changes when you change the EI value). So if you want to NOT show your EI changes on your external monitor, switch the LUT for SDI/HDMI off

[@braybraymitchface]

So let me get this right. The ONLY thing Ei mode does is show you how the video would look after brightening or darkening the image in post? I thought Ei mode was meant to let you set base ISO then CHOOSE whether you want to prioritise more highlight retention, or more dark retention? Is this wrong?

[@RonaldKasper]

Your first assumption is correct. However if you change the ei value and expose differently you automatically give your highlights or your shadows more breathing room in the slog signal. I got this covered with an example shooting in the video as well!

Exactly. Think of it as an exposure LUT that you put on your ISO 12.800 footage to show it darker.

So you would try not to use a EI level lower than what you have set the base ISO to? I am still learning the cine ei so forgive me, but what purpose would cine ei if you don’t lower it lower than base iso? Like what purpose would it serve to film at base 800 and then have the EI set higher?

I shoot news documentary and we are often at the mercy of the natural light in a scene (imagine a dim migrant shelter). If a window can't be opened, I'm used to creating more light by adjusting the camera settings, so if I'm already wide open with the aperture and I don't touch the shutter speed to preserve it's 180 angle, all I have is ISO. Does this mean that CineEI is not a good fit for this type of outside-the-studio shooting? It feels as though having only a high and low ISO setting isn't going to allow me enough control to get correctly exposed images in "wild" environments. Does this mean I should stick to Cinetone for this filed shooting? Or is there another way to film more flexibly and still see some benefits from the log format? Or perhaps I'm still misunderstanding how CineEI is to be used. Thank you!

[@RonaldKasper]

Hi Todd! I do a lot of run and gun shooting as well and I found out that 12.800 iso is suitable for most of the conditions. In combination with the built in nd, I was able to film nighttime scenes as well as in bright sunlight. If you film in custom mode, and you raise the iso above 12.800 it is the same as if you film in 12.800 EI mode and raise the exposure in post. The camera just adds more gain to the signal, like you would do it in premiere or davinci. So there’s no benefit from using a higher iso in custom mode (or cine ei).

[@toddwiseman1421]

@@RonaldKasper Thanks Ronald, just sort of feels like a paradigm shift that I still need to wrap my head around. Maybe some more real world shooting will help. I just feel strange in that range that's between 800-12,800. My old way of thinking would say it's a bad idea to bump to 12,800 ISO when all I needed in custom mode was to put my ISO at maybe 1600 or 3200 to get a good exposure. The notion of bumping to 12,800 (!) ISO then using ND to dial it back just seems absurd (and like it would introduce way too much unnecessary noise from the high ISO) but I guess that's what you're saying one would do regularly with Cine EI. I suppose when shooting anything on real film you are locked into an ISO/ASA for the roll and don't have the ability to jump exposure around using digital ISO. Instead you have to control the light by adding or cutting with NDs or bringing in actual lights. Guess this is similar. Thanks again for explaining so well!

On the FX6. what are the best zebra settings ? You had 77 as your upper limit - is that for white/skin ? What to set the 1st as ?

[@RonaldKasper]

Hi! Yes the second one was at 77% for a whitecard and I set my first one to 44% for a greycard (18% grey). These are values when you use the s709 LUT and monitor these LUT levels as well (so sdi/hdmi output must be set to „MLUT“)

[@perhaar]

I can't understand the necessity of cine ei? If it's to dark use iso 12800 and adjust with ND. If it's to bright I use iso 800 and adjust with ND. My ND almost never leaves the lens and what I see on my monitor is what I get on the file. Why make it more complicated?

[@RonaldKasper]

If you manage to stick to ISO 800 and 12.800 you don‘t need to use cine ei. It has no advantage then. The advantage comes when you want to overexpose stuff in camera and want to see how it will look like after you’ve brought it down in post. Otherwise you have to monitor an overexposed image on set.

[@perhaar]

@@RonaldKasper I think everybody uses ND filters now, so why would you use anything but native ISO? And I don't get why you would want to overexpose anything in FX3. If you expose everything correct (using waveform, zebra or false color) and use a proper conversion LUT with a good shadow compression, you get super clean files. The files coming out of digital cameras today is so clean that we have to add glimmer glass, grain, halition and vignettes to make it look nice 😊

[@smokeyclinton]

The EI does not show a change on your external monitor? I feel like my camera does not do that. I’m confused now

[@RonaldKasper]

There are settings you can change, depending on what you want to see. If you want to have the SLOG3 signal on your external monitor, you can open your "quick menu" (pressing the menu button shortly) and on page 5 you set Gamut/Gamme for SDI and HDMI to "SG3C/SLog3". Then your monitor does NOT change when you change your EI settings because the EI value does not affect your recorded SLog3 signal. If you change the SDI and HDMI Output to "MLUT", the internal LUT of the FX6 and all EI-changes will be shown on the external monitor. hope that helps.

[@KatZak.]

I'm changing the EI level, but the brightness of the image on my monititor does not change. Is there a setting I have turned off?

[@RonaldKasper]

Yes. You have to set Sdi/hdmi output to mLUT in the FX6

[@Evan-tp7ur]

Hey quick question, how do you get the image on the monitor to not change with the cine ei? I have an fx30 and everytime I change the ei value it changed on both the camera monitor and external monitor. Is it a setting of that specific monitor?

[@RonaldKasper]

Hi! On the FX6 you can set which signal you want to send to the external monitor. That's in the SDI/HDMI settings. I chose that the SLOG3 signal should be sent to the external monitor (I don't use the internal s709 LUT that I use for the internal monitor of the FX6). So on the monitor I simply add a phantom LUT to convert the SLOG3 to REC709. But since the SLOG3 signal doesn't change when you change the EI value, the external monitor doesn't change as well.

[@JeffBourke]

BUT in low light, is it better to shoot at 12,800 and boost in post OR to shoot at 25k iso?

[@RonaldKasper]

According to Alister Chapman it should be the same. Both methods just raise the gain of the signal.

[@jacobstone4real]

So I noticed you are seeing what you get on the built in monitor using a monitoring LUT. My question is I noticed the built in monitor doesn’t change when viewing in S-Log 3 (no lut) and changing EI value. Is that normal? I didn’t see a way to enable live view like on mirrorless cameras and I can’t find anything about this.

That's true. When you view SLOG3, the monitor CAN NOT change because the SLOG3 signal itself doesn't change at all when you change the EI value. That's the reason.

Clearest Cine EI explanation out there, thanks! So the Waveform DOES change while lowering EI below base/native, doesn't stay on the original native iso. Would you suggest overexposing on base iso 800 for cleaner shadows as well?

[@RonaldKasper]

The Waveform on the monitor only changes, if you are monitoring the MLUT signal (not the SLOG3 signal). You can change this when you set "MLUT" in the SDI/HDMI output setting. If you use SLOG there, you are really monitoring the unchanged SLOG3 value that is recorded. And this does NOT change as we've heard in the video. So this is important to see a change in the waveform. The recording always stays on the native ISO, only the screen brightness does not when you set SDI/HDMI to "MLUT". In 800 ISO mode, I don't overexpose because I don't feel the need. The shadows are pretty clean out of camera. But I always overexpose by 1 stop when I use ISO 12.800.

It’s the same until you are happy with the exposure on either 800 or 12.800. But when you need to overexpose to bring the levels down in postproduction, you see a much too bright image on the screen of the a7siii. With cine ei you see exactly how your endresult will look like after you’ve brought it down by (let’s say) 2 stops. Just choose an ei value 2 stops under your current exposure (let’s say 200 instead of 800). By the way, the A7siii has a first base iso of 640, not 800.

That way you can overexpose your footage a bit when it is very dark. You do this so that the dark parts aren't so noisy (you record them brighter than they are and bring down the whole footage by one stop in postproduction). That's a common thing and a quite basic concept, you do with most of the cameras out there. But with other cameras, you have to look at the much too bright image on set, you don't really know if the mood in the darkened endresult will be correct.

If you are monitoring in a raw SLOG image, the EI won't change a thing visually.

Hi! That is correct and very clear. Remember, the recorded SLOG3 signal doesn't change at all by changing the Cine EI value, so if you are viewing SLOG 3 on your monitor, of course nothing changes when you change the Cine EI value. You have to activate the LUT on the screen (either the standard s709 LUT that's preinstalled on the camera or any third-party LUT) to see changes when you switch the Cine EI value.

It’s explained in the video. A lot of times we have to overexpose slog3 on set right? Because we record something dark and want to get clean shadows. In postproduction we lower the exposure of the footage that was shot brighter to get the darker image we want, but with the cleaner shadows. So far so good. But if we record it brighter on set, the image in the camera monitor is brighter as well and you do not really see how it will look after the exposure was brought down. And that’s why we need cine ei, it pretty much lets us „preview“ how the image will look after we’ve lowered it. Clear now?

@@Nqrgaard I‘ve never worked with the FS7 but with the FX6 I only need to overexpose with the second base ISO of 12.800. with the first base iso of 800 the shadows are very clean straight out of camera without overexposing.

[@bwest6275]

FS7 has Cine EI?

[@jackmasterson8352]

Took me a couple watch through then it clicked. Thank you.

[@RonaldKasper]

Thanks for not giving up! 👍

[@propellavideo]

Totally lost. Was hoping this would help me understand the mode on my FX6. The base is set to 800, but how do I set the high to 12800? Also, when I togged between the L/M/H the screen doesn't increase in brightness. what am I doing wrong?

[@RonaldKasper]

Hi! Since these are very basic questions, I would highly recommend that you read this excellent description from Alister Chapman before you use the camera: www.xdcam-user.com/2020/12/a-guide-the-the-fx6s-cineei-mode/

[@propellavideo]

@@RonaldKasper very basic? Then can you not help? Can I not toggle from 800 to 12800 using the ISO switch on the side of my FX6? Additionally, when jumping from the different EI’s there’s no increase of screen brightness. Went through Chapmans notes. Still not getting anywhere. Can no one help?

[@RonaldKasper]

@@propellavideo You can change the Base ISO in your menu. The little metal switch on the side is for changing the EI value in the currently selected base ISO. The iso doesn't change when you change the EI. And the reason that your screen doesn't change when you change the EI value is, that you probably haven't selected "MLUT" in HDMI/SDI output in your menu. You need this, otherwise the screen brightness doesn't change depending on your selected EI value. Does this help?

[@propellavideo]

@@RonaldKasper we’re getting somewhere! Thank you! So even for the FX6 included monitor, you have to select MLUT etc? I thought would only be for external additional monitors? Or is it also for the included monitor? I feel this is now helping 👍🏻

[@RonaldKasper]

@@propellavideo The waveform you see on your FX6-monitor gives you the signal from what you transfer via HDMI/SDI. So you have to set the LUT there and the internal FX6-monitor shows you the waveform of your signal AFTER THE LUT was applied. If you remove the lut from the hdmi/sdi output setting, your waveform shows you the values of the recorded SLOG3 signal. And yes, the EI-value is related to this as well. It only works when a lut is set for hdmi/sdi.

[@jpalczewski]

Awsome .. and more videos about FX3 please

[@stealthman448]

Can you do a video on bringing your footage into Premiere 2024!?

[@RonaldKasper]

Sorry, no. I use Davinci Resolve. But I‘m sure there are plenty of videos on KZbin about doing this. What’s the issue you have with it? Does it look like already colorgraded because Premiere throws a LUT on it automatically?

[@jamesmathews243]

Well done, sir.

[@RonaldKasper]

Thank you James!

Great video 🙏

Thanks a lot!

Starkes Video Ronald 👏 SUB from a german FX6 filmmaker 🎥 I takes a long time to understand my FX6 😂 but now we are married 😅 beste filmerische Grüße

[@RonaldKasper]

Ah super, ein Nachbar meldet sich! 👍 Yes it takes some time to switch from a mirrorless camera to the FX6 Nd understand it totally, but it is a beast of a camera!

[@DigitalCrayon]

put simply, each ISO value in CineEI is an exposure LUT !

[@RonaldKasper]

Basically yes. But that doesn’t sound as cool as „Cine EI“ so they created this new name for it 😂

[@jujufactory]

I've been a director for 30 years. I work in Slog now. I have no idea what he's talking about.

[@RonaldKasper]

The video helped the majority of people who watched it, to understand cine EI. Can I help you out with further information?

[@enjoygary]

Can you show us your KZbin setup?

[@RonaldKasper]

Hi! What do you mean? How I set up my room with the lights? That's all pretty standard: An aputure Amaron 200x keylight, a P60c fill-light, a Godox TL60 tubelight on the shelf and two Aputure MCs on the shelf. I think a whole video about this might be too boring ;-)

[@enjoygary]

@@RonaldKasper like a behind the scenes video on how you make KZbin content

[@JeffBourke]

The problem is that if you use a display LUT, the histogram changes with your EI!

[@RonaldKasper]

That’s true but I‘d say thats a feature, not a problem. Because of this you can expose for nor normal levels with any ei value

[@SideTripProductions]

I just tested this on my FX6 and the histogram and waveform on the camera both remain locked when I adjust the EI. I’m using a LUT on the viewfinder but not the SDI or Internal Rec.

[@JeffBourke]

@@SideTripProductionsyeah but Sony crippled the function on the FX30 (poverty camera for plebs)

[@wildwestadventures3583]

Why not just rely on false color? Maybe I'm not understanding the EI process but it seems over complicated and unnecessary. False color has always been reliable for me.

[@RonaldKasper]

It‘s not so easy to overexpose dark shots by one stop with false color (to bring them down later in postproduction to get cleaner shadows).

[@IanSnape]

Its totally bizarre, because you lower the EI value to show required look but still need to add light to raise the white point which then raises exposure so you then you adjust EI again and then add more light to raise white point.... it makes no sense.

[@RonaldKasper]

Which section of the video are you talking about?

[@IanSnape]

@@RonaldKasper from 3:31 - from every reduction of the EI value you raise the EI Value....

[@RonaldKasper]

@@IanSnape the explanation is totally fine. It explains why you use dynamic range in the highlights when you lower the EI value AND CORRECTLY EXPOSE for middle grey at a certain brightness level. Because the level of middle grey is risen towards the brightest area the camera can capture with each lowering of the ei value.

[@MTBs]

THANK YOU!!!!!!!!

[@RonaldKasper]

You’re very welcome! Thanks for commenting!

[@DennisLiveTv]

I still dont understand it. i need like a dummy version for me

[@RonaldKasper]

And here it is. Cine EI only lets you film in your base ISO value, let's say this is 800. Lowering the EI from 800 to 400 is like applying monitoring-LUTs on your camera's monitor. They show the image one stop darker (like it was filmed with 400 ISO) but the camera still records in 800. That way you can overexpose what you are filming a bit (by recording it with the bright value of 800) but already see what it will look like after you've brought it down in your editing software by one stop (so that it looks like filmed with 400). That "bring down in post" is very helpful when you film in dark environments. Filming it brighter and reducing the brightness in post gets you cleaner shadows.

[@glowedupglen]

Thank you

[@RonaldKasper]

You’re welcome, I hope the video could help a bit

[@tor2919]

I still don’t get it. You overexpose the image but display a darker image? What’s the point? Visualisation? Don’t you clip the highlights by overexposing the scene by two stops?

[@RonaldKasper]

Exactly, I display a darker image. The point us that you need to overexpose in darker environments when you want clean shadows. Like shown in the video.

[@Ricadamu]

The concept of overexposing intentinally and then bringing back down in post feels really stupid to me. I don't like this system, it seems counter intuitive. Thanks for the explanation.

[@RonaldKasper]

Well this method is what most filmmakers do in dark environments to deal with the noise. Overexposing doesn’t mean to destroy the image and clip the highlights. It’s just recording everything a bit brighter to get less noise

[@personal4528]

This is a good explanation. But in reality it is just Sony trying to work around their terrible sensors. Sony shadows deteriorate so quickly.

[@RonaldKasper]

Dual base iso is a very common concept among all manufacturers

[@personal4528]

@@RonaldKasper EI workflow is just a fancy way of covering up for the fact that you have to over expose sony sensors by 2 stops to get clean shadows.

[@RonaldKasper]

@@personal4528 true but you see how the endresult will look like and you don’t have to look at an overexposed monitor on set.

[@dragonflymediageraldton5655]

No-one explains how Cine EI works outdoors in full sunlight.

[@RonaldKasper]

Yes because you primarily need it in darker environments. Outdoor the EI value should be the same as the ISO. In very rare cases, you could raise the EI value to something higher than the ISO, what happens is that what you see on screen is brighter than what you record. You basically record an underexposed footage then. I honestly I did never use these settings because there was no need for it.
