Will this lut work with the gh4 ??

[@MforceArts]

I was wondering, since the GH4s uses V-Log as well, would this becompatible? Or is there a difference between GH4 and GH5 V-Log?

[@kimdicentalevankim7023]

Amazing video thanks for sharing! QQ how do you expose for skintones IRE for VLog? Is 65 good enough? And for Cine-D same IRE?

[@alexmack106]

Place skintones between 45-55 IRE for VLog. The Cine-D equivalents are in the Pdf; its about the same for Cine-D midtones. For VLog, 65 and above is the rolloff (avoid placing important scene elements here)

[@davidlongenecker9414]

I see that it can be used on Cine D... Would it be beneficial to use it on GH4 footage? I'm assuming the Cine D color isn't crazy different.

[@CameronGallagher]

Yeah I would say it would work!

[@Laygtraveller]

When I bought the ghalexa lit the documentation said we need to first convert cine D and HLG to log with a Lut they provided and then the corresponding daylight Lut. Is this correct?

[@garydirects]

Sundeep Guntu it’s made for v log so yes if shot in another profile

[@AnalogVoice]

Can I get this to work with cine-d and the lumix G7

[@premshashi]

so do you use the this LUT to replace the rec 709 conversion LUT?

[@CameronGallagher]

Yes!

[@MsYano26]

Which conversion rec 709 LUT did you use? And can I install the GHalex unto the camera to view from the monitor? Thanks!

[@alexmack106]

Yes - with *VLog, you can use .vlt previews. But the .vlts are not very good because of the 17x limitation (prone to banding etc.) External monitors that accept .cubes allow full quality 33x previewing

[@benjaminkessler6455]

Looks great, where do you finde something like this ?

[@Ben-rz9cf]

Would this work with the pocket 4K since it has the same sensor as the GH5S? or is there another one for matching the Alexa (preferrably the XT) with that camera?

[@alexmack106]

It won't - it needs its own version (as does the S, all told). Those are coming up later this summer

[@Filmmaker809]

So, I can import these LUTS into Adobe Premiere CC for my PC? As I do colour grading in Premiere. I have a GH5 as well by the way.

[@CameronGallagher]

Yep! 100%

[@Filmmaker809]

thanks Cameron!

[@TGVG_]

Amazing video! How is this different from the build-in Alexa LOG to Rec. 709 LUT in the Lumutri pannel from Premiere Pro? The build-in LUT creates also highlight fall off and blooming like the Alexa

[@CameronGallagher]

This is HUGELY different! I don’t think the built in VLOG LUT does any highlight roll off, so I’d be careful

[@TGVG_]

@@CameronGallagher Thank you for the reply! The built in Alexa LUT is not especially for VLOG. But is interesting to see that you can get much better colors out of it then a standard LOG to Rec 709 converter. I wonder what the GHAlex LUT can do.

[@bentheremedia3011]

The difference is that the built in Alexa LUT is designed to be used on Alexa footage. The GHAlex LUT is designed to be used on GH5 and GH5s VLog footage to emulate the Alexa look. That is a massive difference.

[@avsvisual6786]

Have you updated to v.4 yet?? The new update is simply amazing, even better than before which I didn't think was possible. He added some Exposure Correction and Auto Black Level adjustments that help you fine tune the contrast precisely. It's crazy good, best money I've spent on a "LUT". I don't even like calling it a LUT. I don't know what it is, but it's better than a regular LUT

[@SvenKucinic]

Does this works with Lumix G7 or G80 with cinelike-D?

[@lortakeover2129]

can you do a walk throught of using it,? slowy its four luts the main,soft,daytime log c, do i apply more then one ,do i apply it direct on the vlog footage

[@CameronGallagher]

All you need to do is just Apply either the daylight or tungsten to your V-Log Footage! I recommend adding a node before to correct any exposure issues and white balance issues, but just on the VLOG

[@lortakeover2129]

so what about the daylight log c,lut , i would apply that and the daylight soft, i guess that why it dont look good

[@MrSanderrrG]

Hi Cameron. Is this LUT destructive? In other words: does it crush the blacks / whites if the exposure is incorrect? Because if it doesn't, to me it would make more sense to do exposure changes post-LUT (as Leeming LUT recommends).

[@alexmack106]

Indeed, the ideal use of EC is to place the luminance shift *after the conversion, to maintain LogC accuracy (and expose moderately for the desired end result in camera), though there are creative benefits to placing luma before the conversion should it be desired

[@stilmotionpicture]

Bought it. Tested it. LOVE it! Also if anyone is wondering, this works really well with EVA1 VLog footage as well. Follow the steps in the included .pdf and you will be extremely happy with the results! Plus, you will learn a lot! You pay $65 for two LUTs and you gain some valuable knowledge. It's a slightly longer workflow than if you were to just drag and drop a typical LUT onto your footage but the bright side is that you'll be really happy with the image pretty much right out of the box so you won't need to do much tweaking if you expose your image properly in camera. HIGHLY RECOMMEND!!

@@CameronGallagher Okay awesome, thank you!

[@alexmack106]

I'd actually recommend placing skintones between 45 and 55 with VLog L. Avoid below 40, or above 60 (above 65 is the rolloff region). By moderately exposing, the clip won't require luma adjustment before the conversion, which allows complete accuracy for the LogC transformation at core. Hope that helps!

[@CountSorinsRealm]

@@alexmack106 thank you very much kind Sir! After testing I did notice that above 60 it tends to wash out skin tones so I'm going to probably have a secondary zebra at 60 IRE for skin tones.

[@TheDarkSirius]

can this work whit my gh4 ?????🍁

[@CameronGallagher]

Yep!

[@Tadwilla]

Something is wrong, need help! usually I shoot cinelike D and just simply adding cinelike-D to rec709 lut. The picture is pretty good after this, I don't see any overexposure, or something bad with my video shots. just minor problems that can be easy fixed. And now I have tried ghalex lut on the same track, and I have big problems with overexposed washed out images. 1) first step was cinelike-D to v-log conversion 2) adding ghalex lut after these steps the result is- everything overexposed and washed out. Is it normal and I should work with bringing back normal exposure and contrast as it was before? I just want normal image as it was with cinelike-D to rec709, just using ghalex colors instead of rec709.

[@CameronGallagher]

The main issue is that concerting Cine-D to VLOG isn’t really a true conversion. Cine-D has much less DR, even when properly exposed! GHAlex has a Cine-D LUT I believe! The GHA LUT does slightly bloom some highlights but my guess is the conversion is where the issue is! Try a few other clips, and try exposure changes prior! Also, I can’t recommend the VLOG upgrade enough!

[@Tadwilla]

@@CameronGallagher after cinelike-D to v-log conversion, it looks like v-log, but the main problem is, that after cinelike-D to v-log conversion the image becomes lot brighter, and it's very difficult to fix. I don't really care about less dynamic range, I just want the same cinelike-D image quality with ghalex colors. By the way, let's say I shoot v-log, is it enough to put ghalex lut? should I do color grading, add contrast after this lut. I just want to keep things simple, can I change cinelike-D colors to ghalex like I change it to rec709? If it's impossible, how can I bring back my image quality I had before cinelike-D to v-log conversion? I want similar brightness and contrast like original cinelike-D image without much work.

[@CameronGallagher]

So the problem is, even though it may look the same, the way the footage works is very different, which is how the GHAlex LUT works. Personally, I do ALL exposure and basic color corrections before any conversion LUTs

[@Tadwilla]

@@CameronGallagher I see, but what if everything is fine, exposure is pretty good, no need to correct anything, but after this cinelike-D to v-log conversion things become complicated. contrast is lost, footage is overexposed, and the whole image doesn't look right. everything looks pretty good if I am converting cinelike d to rec709. I can't understand it, what I am doing wrong.

[@gregorgraschitz]

Does this lut work for canon cameras too?

after watching this video, I gave it a try. I shoot most of my stuff on Cine D. I found a workflow that works for me. First I convert the Cine D into Vlog Joo.Works Lut. Accordingly to him Cine D has the same amount of information as VLOG. I believe him.. Anyways, after that, I apply the Alexa Lut. Then that's a fantastic start for grading. There is something magical about this LUT making things little brighter. However, I have had noticed this workflow altering a lot of red and blues, but easily fixable.

[@alexmack106]

Paul - Cine-D is natively supported - use the Cine-D PRE in advance of the conversion. It is much more accurate (made with the same system as GHa itself). Cine-D does have the same information as VLog, the only difference is that ISO 400 is labelled as 200 for Cine-D.

[@joyoffilming9500]

Great results shown in the video. Anyway, by comparing any more professional conversion LUT to the Panasonic Rec709 conversion LUT will end up in a similar way. There should be a comparison of this LUT against a proper color space transform (CST) from V-Log into ARRI LogC, then adding some grading, and at the end of the node tree another CST to Rec709. This approach allows to take benefit of the nice ARRI ALEXA color behavior when grading, instead of converting the GH5 wide V-Log gammut into a narrow Rec709 gammut at the very beginning of a node tree.

I had same idea :) what I do in DavinciR 18.5 beta2 : 1/ in project no color management 2/ in the nodes section: from V-Log into ARRI LogC -> CST: from ARRI WG 3/ARRI Log C3 into DAVINCI WG/intermediate -> ....edit .... -> CST: from DAVINCI WG/intermediate into rec709/gamma 2.4 So that my edit stays in the DAVINCI Wide Gamut color space.

Hey Cameron, I sent out an email ;)

[@SheldonCharron]

Honestly I think the rolloff is the biggest reason to use this LUT. It's the only thing that really sticks out as unnatural on the GH5. The colors aren't so bad, and unless you have a side by side, most won't notice and it's more about preference, but the orbital roll-off just looks totally weird on the GH5. The before-after rolloff image on your website really show's the difference. I don't have your LUT so haven't checked it with 8 bit, but the GH5 8 bit v-log has always been really bad to convert so I avoid using it, otherwise, most of my sports and outdoor work I would shoot almost exclusively in 60p. I think that's an area you should really focus on explaining more. Maybe give a few more comparison examples of your LUT on 8 bit footage vs. the standard rec709 conversion. Great work dude.

[@just.do.something]

Thanks for the vid. Really want to like the Alex LUT, but I gotta' say, I prefer the Rec 709 LUT, just looks more natural to me. I'm really trying to see the nice highlight roll-off your describing but I just can't see it. Anyhow, I do think the Alex LUT gives a specific type of look that many people are going for these days, but my personal taste is that it feels too warm/and bordering on taking away from the wedding moment. But, great shots man. Looks like you did a heck of a job filming their wedding.

[@alexmack7610]

Herbie, thank you for your thoughtful, polite response! It has been hard reading some of the less informed reactions here. This is a raw rolloff comparison: emotivecolor.com/img/v3rolloff.jpg The core conversion is actually to LogC, as measured through the lens (without a look). Cameron was actually using a look lut after GHa for the wedding shots here. Apart from LogC, there are three neutral color base options - Main or Soft (which have the lowered 'Sicario' 75 IRE highlight ceiling, and Linear, which is very contrasty like the LogC+R709 route. The unifying element between these three EC variations is that they have a film-styled envelope in addition to LogC and the Arri 709 primaries (built in to one), not unlike a standard Technicolor handling of Alexa footage. Here is a video with the raw 'Main' variation (no color grading whatsoever): vimeo.com/280805489

I’m impressed, where’s my wallet...

[@Renaldo868]

Bought it today. It's cool but I prefer the vibrant look from Joo.Works. I haven't seen any benefit of the smoother highlight roll off just yet and I find the skin tones and just over all saturation of the image just too dismal for my liking. However I like in the Caribbean and my clients prefer a much more vibrant look to their content so maybe that's why my eyes don't take too well to this. I don't regret the purchase though because it is an investment and may come in handy at some point to correct some blown out highlights or something BUT if you have Joo.Works and love his then you won't like this.

The title has a misleading information, the LUT isn’t compatible with GH5s , only with the GH5, I have just spoken with Alex and he confirmed that. He will be releasing a Gh5s LUT soon.

The wedding clip looks better without the lut

:( i don't see it.

[@qtben17]

6:21 looks more of a teal and orange lut. Wedding dress suppose to look white/beige. This comes out with teal shift. And the skin tones, do they have fake tan in real life? It is orange-y.

[@alexmack7610]

It is - Cameron was using another look after GHa here. This is the raw GHa (no color grading): tinyurl.com/y9luaz6t

[@CameronGallagher]

Yes I’m using a stylized grade, which I mentioned in the node tree breakdown. Our weddings are stylized, but the GHAlex LUT looks great underneath

[@LeighMakesVideos]

Hi. If you are using Resolve to grade, why not just use the color space transform effect to emulate the Alexa's awesome highlight roll off? Works great with my S-log 2/3 footage. Could be worth trying out with V-Log. This LUT seem great for PP and FCP users but Resolve users can probably save some money.

[@CameronGallagher]

It’s not exactly the same! The color transformation is great, but I’ve found your not getting the same natural look, and it’s more of an “under the hood” change. I use that when I’m using LOG C LUTs mainly

[@alexmack106]

Hey Leigh! Resolve + CST is a great tool indeed. The way this differs is like a tailored suit compared with a suit, so to speak. Every tiny nuance of both cameras' actual color sci result has been measured, with a computed transform between them.

[@VideosProva]

Please Alex, (or someone else) make a simple video comparison like this: first use built-in Resolve openFX effect color space transform + Resolve built-in Alexa LUT like showed here (here he also tested it with exaggerated example of overexposure to see the still perfect gradual roll-off): kzbin.info/www/bejne/oJqTfIisl7x6gZY and then a comparison with the original clip with the GHAlex LUT. So, original clip with SKIN face, with only that color space transform and a comparison with only the GHAlux LUT (Eventually with slightly same saturation for both the transform). This basic setup, plus, if you want to, another clip but overexposed with the same procedures. I think it's the only way we could appreciate what's the real benefits of this LUT that is promising. Thank you, best regards.

[@alexmack106]

Will do!

[@biscuitsalive]

Nah, I was excited about the idea of this LUT, but your demo made me tip away from it, pretty sure I can get that look manually fairly easily. tip off the whites early, bring up the mids, and warm up all the highlights etc

[@ricktim8402]

If u make one for S-log and it looks like this, I will be willing to pay money for it. In fact I think alot of people would.

[@biscuitsalive]

Christ Timbuleng tell you what il have a go at doing it manually today. If I get a good match I will post s video showing how to match the look for free. :)

@@ricktim8402 Almost there for Sony. Also, I should mention with regards to the core LogC variation, it is a 1:1 measured conversion, rather than a look (this video used an O&T following the V2 conversion) . I did this by writing my own interpolation engine in C++ and creating a color sample system that nets about ~27K samples per camera (still working on it)

The shots kind of looked better with the 709...

[@alexmack106]

Different strokes for different folks I guess! It might be that the video only shows Main (this came out before Linear, which many prefer for the higher contrast ceiling)

[@rizzo-films]

Yeah it's a preference thing. I personally like a bit less contrast, like that filmic look, which tends to pop more in darker rooms like a theater or a living room with the lights off when you're watching a movie and you can actually see more. On mobile or computer screen in a brightly lit room, higher contrast tends to pop more.

[@TrillShatner]

This LUT is powerful, mostly because the GH5 is powerful.

[@alexmack106]

Indeed, the GH5 is a fantastic cam. I knew when it came out that this was 'the one' for this project. Built in 10 bit and All-I laid the foundation for EC (the P4K will be optimal too, but I am reticent to support 8-bit cams)

[@TrillShatner]

@@alexmack106 I enjoy your ingenuity and attention to detail regarding the use of outside software & plugins to ensure your desired outcome & would like to purchase your LUTs. Since I don't personally like davinci, I would venture to ask whether or not you feel SA Color Finesse 3 (standard with new versions of After Effects) would suffice as a white balance tool for your technology?

[@alexmack106]

@@TrillShatner I know that AE has a .cube loader; as long as the WB tool in question is dedicated to that purpose (the Temperature and Tint controls), it should suffice. I haven't documented that workflow, though the basic order of operations and principles from Resolve and Premiere would apply.

[@ciao_abhi]

no offense but the GHA LUT looks overly processed, amateurish ... looks like a really harsh instagram filter in my opinon... look how orangey 6:47 looks and how harsh the highlight is. Alexa looks smooth, low contrast, and kinda flat. Thats what give it a "film look". This lut is so harsh on the highlights and wayy too much saturation.

[@alexmack106]

Abhi, an orange and teal lut was used on top of GHa in this video. Alexa shoots to LogC - which is what GHa converts to for the core variation (measured camera to camera, not CST). I own the Alexa - which is how I made the conversion. Here they are, in side-by-side with Arri R709 applied (Panasonic V35 for reference): flic.kr/s/aHsmzCgFFP And the raw footage from each: www.mediafire.com/folder/x3ub82eh21u63/ALEXA_vs_GH5_(Side-by-Side)

[@craigw.scribner6490]

kinda sorta

[@likebliss]

Wtf... $65 to crush highlights??

[@CameronGallagher]

It's not crushing highlights. Yes it's changing the 100 IRE to a lower number, but also doing it with a blooming effect. PLUS it's also replicating the Arri color space. Very different stuff under the hood

[@alexmack106]

@Bliss Garcia Have a closer look - the other two variations are LogC and Linear, with which the highlights are, very much so, linear.

[@likebliss]

@@alexmack106 sure, but the max ire went from 94 to 76. I like a smooth roll off, but not at the expense of the white point

[@alexmack106]

@@likebliss That is, the Linear variation rises to ~91, and LogC+R709 to ~98. Main/Soft go to ~76, they conform to the Sicario ceiling: flic.kr/s/aHsmBm8USe Prolost: prolost.com/blog/hdrtv

[@aydenbyrnes]

You can get pretty much the same or better results with the highlight rolloff using the high/high soft sliders in the "soft clip" section of resolve (the sliders do not cost $65)

[@alexmack7610]

Here is the rolloff of GHa: www.emotivecolor.com/img/v3rolloff.jpg The Resolve tools are nice, but entire focus of GHa is to measure exactly what each camera is doing, and do a precise transform between them. From before: "Hey Tom, yes Resolve is a great tool! The CST feature is really handy and I love it. That said - I made this because it is so much better ;) The inverse is the case - Resolve CST is actually a kind of general fix all that is not tailored to the actual measured color sci results of each camera, but rather uses the parameters of the camera color space that were released from the manufacturer (i.e. generic VLog and V Gamut - both for the Varicam and the GH5) What I did, (because I am obsessed with this singular goal) is measure the actual camera results using a color sample system that nets 27K sample points. Then, I coded a program in C++ to do the transform between them (a tailored process, if you will)" "If this is in any way a financial stretch for anyone, I don't want them to get it (granted, they likely wouldn't have a GH5). I have put my heart and soul (and significant investment) into this for so long now, issuing free updates to everyone because I want them to have the *very finest work of which I am capable. Take a look at the raw footage side-by-sides from each camera - these are provided so that everyone may confirm for themselves that every single point in the VLog color space has been seamlessly matched to LogC, as measured through the lens. For some, this is worth it, and meaningful, and for others, its not. And that's ok with me."
