Wait u guys don't know how to get a 4k60p full frame on the a7iv? Easy , wait for it. This actually works and u already knew about it. Here it does. , Speedbooster + canon ef lense = done, a 16mm ff lense would be ff but of course its not native. What will blow your mind even more is that if you don't use crop mode and use a speed booster you can get extra light for the subject and be able to drop the iso

Doesn't matter, the A7iv is still sharper than the A7S3 below 12800 ISO. But rolling shutter though... man the A7iv is a complete letdown.

Gerald una consulta, en el modo 4k 60 fps 1.5 crop se ve afectado el rango dinámico por tener un tamaño más pequeño de sensor. Porque si no se ve afectado el rendimiento de rango dinámico se derriba el mito de que el sensor apsc tiene menos rango que el Full frame

[@TerryWarfield]

Saw this being talked about on Facebook today and thought, “let me beat Gerald to the punch making the video” and, well, here I am, you beat me to the punch 😂😂

[@thisiserich]

You should try out 1080p in aps-c mode with clear image zoom on. It does give a 2x crop but the 1080 that comes out of it has no discernible difference between 4k. It’s crazy. I feel like the A7IV has so many secrets that have yet to be revealed haha.

[@djrease7354]

I have heard of this secret… I will definitely give this a shot.. A lot of hidden gems but it might be Sony’s way of getting around the limitations of the camera…Without actually stating it.. and I also wonder how it would look in HDMI only output mode

[@maszekmeans]

Amazing !! 💛💛💛

[@LumiereProductionReunion]

Hello, Great video! Just a question about your Sony A7IV on your left. Is it a dummy battery connected to the camera ? If yes, is it a good solution for alimentation ? and for overheating ? There isn't problem using it ? Wish brand are you using ? Thanx!

[@marksummers5504]

This proves how minute the actual differences are when you get to that level of clarity. We still don’t have any largely available 8K TV’s available so much if this is kinda pointless. I understand that many are recording now, for the future technology.

Would it assist in the workflow if you upscale in external recorder and sharpen in post to clean up the 4K to look close to real 4K? Just wondering

[@jaapkamstra9343]

Cool stuff! Great teamwork on figuring this out. And yeah: for me 4k60 matters. I use it a lot when filming. And I also like shooting wide. So having no crop helps. Because I need to bring/buy less lenses. Still a happy fuji x-t3 shooter.

And your fuji is already aspc ? so its same

[@troyphillips1077]

I am thinking of getting this camera as my general carry camera and use it for videos too along side my a7siii.

[@VideoTechExplained]

Always appreciate informative videos like these! Based on how severe the rolling shutter is on the A7IV, I had my doubts that the 4K60 crop was some sort of snake oil artificial limitation. However, it's nice to see these sorts of ideas being investigated even if the outcome isn't all that unexpected!

[@JetBen555]

''Based on how severe the rolling shutter is on the A7IV'' all the other FF camera in that price bracket have similar rolling shutter in 4K30 but on the A7iv you can get really good rolling shutter if you shoot in APSC mode.

[@JonPais]

@@JetBen555 If we're talking value, the Sigma fp, Panasonic S1 and S5, the Nikon Z7 and Blackmagic Pocket all offer the possibility of RAW video at that price point. I don't purchase a full frame camera to shoot cropped APS-C!

[@JetBen555]

@@JonPais I don't really see the point of your comment, I was not talking about value at all. Just pointing out the *fact* that other Full Frame camera at that price point have similar rolling shutter as the A7iv in Full Frame 4K30. (despite the fact that they all have lower MP sensor) But I will bite You need an external recorder to get ''Black Magic Raw'' (which is not Raw) on these camera ... soo how can u even talk about ''Value'' when you actually need to invest several hundred dollars more AND carry a Fking big a$$ monitor all the time to get additional features from your shitty camera with terrible rolling shutter in full frame 4K ?! Also, comparing the Blackmagic ''Pocket'' camera to the A7iv is just laughable. It's a huge beast, it dies in 30 minutes unless you mount a huge V mount battery. The footage don't even look that good and doesnt offer much in term of flexibility in post (compared to SLog3 10bit), it has no stabilization or auto focus, its really not comparable, outside of the price.

[@JonPais]

@@JetBen555 Sure, Ben. Few other cameras at that price point have as severe rolling shutter as the Sony. Few other cameras at that price point lack RAW capability. When you talk about price point, you are talking about value. Look it up, Ben.

Ciao Gerald! Did you try to turn off the internal recording and record only on the ninja?

[@billpolitis8855]

Hi Gerald! Does the Metabones 0.71 ef-e mount adapter fits on A7iv??

[@AmadeuszAndrzejewski]

The A7 IV sensor is too slow to do 50/60 fps, the readout time was around 24 ms when I measured it. This still means the crop could be reduced to around 1.2-1.25x in 50p and 1.25-1.3x in 60p but that's up to Sony engineers to maybe do it as a firmware update

[@SimeonKolev]

They can squeeze some speed if they use pixel binning but 7K is not the resolution for that... They will get 3.5K 60p.

[@AmadeuszAndrzejewski]

@@SimeonKolev true and that would also be better than what they offer now

[@masterofdister420]

max 41.67 frames per second if youd do a full frame readout

Lovely.

[@charbax]

This is why I use micro43. I was hoping GH6 was getting 4K60 with PDAF to dual SD, but they skipped PDAF and ended dual SD. So maybe the OM-1 is an option going forward. As my G9's AF is bad.

[@kifley19]

No dual recording on the OM-1

@@kifley19 what do you mean surely the OM-1 records that 4k60 h265 10bit 4:2:0 to both se uhs-2 cards at the same time.. right..

[@StudioNirin]

I'm confused, 4k60 on m43 only happens because of the heavy crop... You can't do anything on m43 without a heavy crop

[@NicMediaDesign]

iPhonedo is the best Sony reviewer.

[@clifftotten7609]

It's just a 1080 binned sensor read. The Image processor is only getting 1080 raw read from the sensor A/D converters. This is an "on-sensor" photosite bin. So there is nothing that the image processor can do about it.

[@IamMannyLaws]

Hearing iPhonedo saying “alright I’m done” was epic 😅

[@yerkohernandez9097]

what is the dynamic range of this camera in 4k 50 or 60p crop mode. I have seen youtubers like matti haapoja and Chris Brockhurst say that the sony 10-18 lens is an amazing lens for sony in crop mode like the a7iv. I am very interested in knowing the dynamic range of this a7iv in apsc mode and knowing how much I lose vs the full frame

[@Chaelaz]

Isn't it that the processing power of the camera cannot read the full sensor 60 times per second in 4k, so the crop is in place? I was thinking it might be something that could be a software upgrade, but I don't think that can happen if the processing pipeline just doesn't have enough bandwidth to do it. Unless maybe they can optimize the code to read faster within the same processor speed confine. But then I also wondered, since it is taking a 7k over-sampled image to make the 4k, maybe the sampling could be stepped down to take up less processing power and allow for the full frame capture of 4k60p? I have no clue, but would be a neat video to hash that all out for better understanding. Cheers.

[@CeejCinema]

Is the 4k output to a ninja V the same downsampled 7k from the sensor? If not Then maybe that’s why 4k 60 cropped internal looked better than 4k ninja v?

[@illuminatusstudio7479]

Hi, love your videos, very detailed explanations. Would be possible for you guys to test this on the A7IV Film in 4K60fps SS250 then reduce to 25% speed in resolve using Optical flow and Speed warp and compare it to A7SIII or FX3 120fps.

[@Mirsab]

The smile that this video title bought me

[@Athiril]

You could have also compared it to 4K30, as that’ll give 4K resolution full frame for the test purposes.

[@OurPastSecrets]

Was surprised they didn’t do this, seems most obvious

[@KrunoslavStifter]

Guys can you maybe do a test where you take 1080 60p and upscale it to 4K 60p with Topaz Video Enhance AI, preferably the latest version of the software? That would be interesting to compare to original 4K quality. Thanks.

[@boxemail6697]

Hello sir could you tel me witch lens i choose for a7iv 4k 60fps crop to cover 4k 60fps full frame without loosing resolution?

[@nelsonpuello8722]

I ran into this by accident with my A7SIII + Ninja V, and trying to use APSC mode/lenses. I did not do as extensive or meticulous testing as you guys have done, but I noticed the difference right away. In short, I just use Clear Image Zoom with my APSC lenses on the A7SIII, as it is a higher quality image than implementing the hack in question.

[@baqcasanke]

Hmmm on my fx3 the clear image zoom might as well be a crappy 2x digital zoom like on old web cams..... it makes my footage look horrible. Just god awful..... what am i doing wrong?

[@nelsonpuello8722]

@@baqcasanke I can't speak to the FX3, as I don't have one. Clear Image Zoom is definitely a "gimmick" that cannot fully replace the role of lenses. But on my A7SIII it sure beats the APSC mode which is only available at 1080p. To my knowledge there isn't right/wrong about clear Image Zoom. You just use it, and there aren't any additional settings. But as I said, Clear Image Zoom is a gimmick that I would not rely on if I had other choices. It does beat 1080p on my camera.

[@AJCoReTV]

Could I just use a 12mm apsc lens to get a 20mm equiv 4K/60 on A74?!

[@JasonsLabVideos]

To bad we can't do this with the Eos-R. Liked and subscribed & followed Iphondo

[@nieebieesk1]

Wait, so just to make things clear cause I'm a bit confused: does it all mean that if I want to record 4k60 (or 4k50 in my case) with my Sony A7IV + Ninja V I should record the file internally to the SD card and treat the Ninja just as a monitor because otherwise I will end up having a 1080p file upscaled to 4k on the AtomX SSD? And if so, this eventually leads to the conclusion that using the Ninja V as a recorder only works if we record 4k24/25 - am I correct?

[@DSLRDIY]

That's the most expensive iPad stand I saw. Love the vibe of both

[@lythnork6131]

Should I buy a Sony A7IV or BMPCC 6k Pro as a Music Video Director and Some Comercial works? I’m really use to have my Camera on a gimbal almost all the time and i really love Sony Auto Focus but idk if I will need that extra 6k quality and internal filters of bmpcc 6k pro… there is a lot of good cameras on the market rn for an affordable price and it’s kinda confusing select one! Pd: I need to buy good lenses so that’s why I can’t afford Sony A7SIII

[@gabmilitao]

C'mon Gerald, you know what we want... We want 2018 Gerald back with a review of the OM-1 and the GH6, please.

[@pabloarribas550]

Hello Gerald, I got lost... Did you try comparing the internal 1080 60p with the UHD 60p downscaled to 1080p? Does it gate any sharpness improvement? Big hug from Chile

[@Knowbody42]

So, it can't really do UHD 60fps without the crop, it's just 1080p 60fps upscaled to UHD. So if you do that, it's basically just being upscaled and then downscaled again. But if you're talking about the real 4K 60fps mode (which is cropped), then you often get a sharpness improvement, as long as it's a good quality encode.

[@pabloarribas550]

Thank you! I was just wondering if you upscaled through the Atomos to 4k and then scaling down back in post, may add a little crisp. I understand is the same going up and down, but I was just curious. Have a good night!

How does the A7IV preform with the Atomos Ninja V for normal usage settings? I know it doesn’t support raw, but can it still record regular pro res in 4K?

[@chphotovideo]

The ninja performs wonderfully! Not had the a7IV long enough for a full run but on the surface it's great. It will record 4k 24/30/60, albiet the 60fps is super35. I was recording ProRes 422 in 4k. Both 'true' 4k and the upscaled 4k example in the video.
