It's probably a closer 1:1 pixel ratio than the 4k in Clear image zoom. Its one of the best reasons to use a Sony camera, other manufacturers just digitally zoom (crop) the image, but Sony actually algorithmically downsamples whatever image field of view you select into a full resolution cut out. No loss of fidelity using clear image zoom. The A7IV has 33 mega pixels, and 4k resolution is aprox 8 mega pixels, and 1080p is 2 mega pixels. The A7IV apse mode is 14 mega pixels, still more than capable of producing a full resolution 4k image, which is why it can crop down an extra 50 percent and still stay full res 4k, because it is now punching in to the very center 8 mega pixels of the sensor. An extra 100 percent push in would be 2 mega pixels, which means at 2x clear image zoom in APSC mode, its a 1:1 pixel read out 1080p image. You are using the 2 mega pixels at the very center of the sensor, at their full resolution, which is why the final result is still so clean as opposed to other manufacturers who take a 4k image and crop it down, giving you a worse sensor pixel to image pixel ratio.
Lumix S1H and S5ii(not the OG S5) have also the same function . When you turn on APSC mode in 1080p the quality is much better because it downsampling Instead line skippingim and look almost like 4k
The "magic" is simply the fact that the camera is reading out all of the pixels from the APC-crop and then subsampling to 1080P relative to the clear-zoom level you've chosen. If you prefer to see exactly what you're getting in camera, this is the technique for you. If you'd rather have flexibility, cropping in post is the technique for you. It's wonderful that Sony gives us both options.
correct me if i'm wrong here but in terms of 4K output, there isn't too much difference when comparing 1. zoom in post and 2. crop + CI-zoom, right? so, no objective reason for one or another, it's just a matter of preference pretty much. when it comes to 1080p output on the other hand, using crop + CI-zoom is of course clearly looking better than zooming in post, since it's an actual readout of a smaller part of the sensor instead. but let's say one doesn't care about file sizes, what'd be the reason to use 1080p in the first place anyway? crop + CI-zoom works in 4K also and it's much higher bitrate. or am i missing something here? or is it that you only get .5x additional extra CI-zoom in 1080p? if that's the case, to sum it up, in terms of image quality alone, the only real advantage of using 1080p with crop + CI-zoom would be that extra .5x reach, right? that is, if you're OK with only 50mbit bitrate.
@@chico3517 Hey there! You seem to be wondering wether there's a difference between using APS-C mode/clear image zoom in camera VS cropping in post, yes there is, and it does matter. When you shoot on the A7III for example you are reading off a 24mp sensor, downsampling from roughly 6K down to 4K. 4K resolution works out at 8.3 Megapixels, this means the camera has plenty of room to crop in from the 24mp sensor readout PRIOR to writing the file to your memory card before you'll get close to hitting that 8.3MP limit of 4K. That is how there is next to no difference in sharpness when using APS-C mode or Clear image zoom; it's because no matter if you use the full sensor read-out or one of the crop features, the resolution of the actual video file written to your SD card will be the same, 3840x2160. However if you record the full sensor readout image and then try to crop in post to achieve the same scaling, you're not cropping from the original full sensor readout like how your camera can do internally, you're simply scaling up that 8.3mp/3840x2160 of resolution (your 4K file). This means you will IMMEDIATELY start to lose resolution. So yes, it matters.
@@09williamsa thanks for your reply, but that’s not what my question was about. i know the difference between internal sensor cropping and simple upscaling in post. what i‘m asking is this: what are the benefits of using APS-C + CI-zoom in 1080p over 4K, other than smaller file sizes? one reason could be that .5x extra CI-zoom that one might not get in 4K, which i'm not sure about so i wanted to clarify on that.
It's great to see that Sony allows for a 1:1 readout on the sensor of 1080p material in some form. I was wishing that somehow the A7iv 1080p would be improved in this iteration so we had a sharper full frame 60p / 120p option. Great find here!
Wouldn't a 33-megapixel sensor's 1:1 readout still be far greater than 1080p (around 2 megapixels)? I think the sensor is switching from line-skipped 1080p to down-sampled 1080p.
Great mention Jason! I have many APS-C lenses and also shoot many of my videos in 1080p. When I first picked up the a7iv I was curious about how is the 1080p video. I was surprised about how much detailed is the 1080p in crop mode. It looks like 4K!! Much better than my a7iii and my a6600. That's a huge advantage of the a7iv.
I was one of those people waiting to get this info and you absolutely delivered! What an absolute trip! Unfortunate that 1080p is capped at 50Mbps, but if I absolutely need that reach it's there!
I just tried 4k30p cropped mode and HD30P cropped mode, really no perceivable difference in sharpness, details, and color (almost 90% similar). I am excited! I will be considering using HD30P to shoot long hours videos, it will be less heat, more storage savings, and longer battery life then.
Shooting any sort of events, especially live streaming, it's a game changer. Being able to use a tiny Sigma 56mm on the APSC bodies and still get a really clean image at 2X crop (~150mm) is a total lifesaver.
I know I’m really late to the party but just came across this. We often use a Sony 100-400 for live streams (not recording in camera for the most part even) to track speakers on stage. Especially for those venues where we have to be quite a bit further back. So we either rent in 2x converters for our 70-200mm or rent in a 100-400mm lens. Now with this, our 70-200mm would become a 160-450mm without any extra cost. Definitely have to check out that feature
Great video and thank you for explaining this. The reason you don't get the same depth of field at 2x zoom is the aperture halves with zoom. So a 100mm F/4 will be 200mm f/8 at 2x
Although I am late I gotta say that's the beauty of Full Frame Sony cameras the 1080p are crisp, unlike from other brands, but If I would say, the one thing could compete it is probably the Panasonic S lines and the GH lines, aside from that probably the EOS-R all-i but with huge file sizes so it's a disadvantage.
This video is about 1080p. Why 1080p full frame mode looks crap with clear image zoom but 1080p apsc mode looks amazing with clear image zoom? How to explain this.
Great video, thanks! One point: You are right that punching in doesn't give the same shallow depth of field performance as a telephoto, but it does give the same compression given the same composition because you will have the same camera to subject distance. Cropping in is equivalent to using a smaller aperture on a telephoto: when you stop down the telephoto lens you will get a deeper depth of field but compression is not affected.
Great video, thanks for the tip! But you made a mistake in the calculation with the 100mm lens. You ended up with 250mm. But you can't multiply the 200mm by "0.5". You have to add the "0.5" to the "1.5" and then multiply that by the 150mm. This brings you to 300mm. Apart from that, a great video! keep up the good work!
Many people think that Clear Image Zoom....is a digital zoom on an already de-Bared image. It's not that at all. It's actually a live-moving sensor window read in raw. The readout is dynamically opening and closing and sending its read data to the A/D converters. This is a raw-read crop, its like taking a full frame read then a super-35 read and even down to a read window similar to micro 4/3 box. This is WAY different to just shooting in full frame and making it into de-Bayered video and "zooming in" on that already processed video in post. This read tecnique is radically different.
@@muen1842 Decreases sensitivity? What do you mean? If you take a raw full frame image in Photoshop and you crop it, does it get darker? No. Cropping a sensor does not make the new image darker. It just changes the resolution. The photosites in the middle of the sensor have the same sensitivity as the photosites on the outer edges. Sorry,... I don't understand your question.
I find out why i was not seeing vignette with aps-c lens in FF mode with a7IV because i was in active steadyshot so that 10% crop is enough to take the vignette almost out you see just tiny bit in the corners
First of all, love your video’s very informative and always great to watch. But I’m actually walking into a head scratcher here.. Did you match the FOV, (field of view) through changing the focal length between the 4k and 1080p aps-c shots? If I look at 2:36 and 2:41 it seems to me, you have shot at different FOV. --When you start with a different FOV, the optical difference/zoom is already making a huge difference for the end results. If I need to shoot in aps-c, but want to keep the same FOV, I have to change to a lens with a wider focal length to match the FOV I would get with Full Frame, where as the difference in DOF (depth-of-field) is a simple lens setting correction. With the a7IV where the 1080p in aps-c is indeed way better than 1080p Full Frame, I run into these changes when I want/need to shoot 1080p. So why? ..If I want to see the true difference between 4k and Full-HD I don't start with the same FOV?, (It doesn’t matter if it’s Full Frame vs aps-c crop) When you start with one having a wider FOV than the other (here for the 4k), that one has to zoom in much more to match the Full-HD aps-c image, hence it degrades more... and you will see less of a difference in quality between the two. Anyways... these are just my two cents, --Still a nice video by the way.
Nice info. But what happen if I don't want that much close up. 1080p aps-c and 1080p ff. 60fps and 120fps. Will there be any sharpness difference? Thanks.
You can use crop mode and clear image zoom in 4k as well. The clear image zoom is limited to 1.5x but you can then crop that 4k video to 1080 to get even tighter.
Actually it is easy to understand. When you crop in post, you are reducing the resolution. But when you use clear image zoom you keep your HD resolution. That's all.
Wow! I just subscribed after watching this (and the one about the vest & arm combo)...THIS is a REALLY BIG DEAL for sports (and wildlife) shooters, as I have often used an APS-C or a Micro Four Thirds (with vintage 70-300 zooms) to get the most telephoto reach!
This is super interesting... I was trying to figure out what is happening here. Is it possibly that Sony Pixel Bins their 1080p when it's FF, but in the APS-C mode it is downsampled from that 4.7k? If I am not mistaken the 1080p is downsampled from 4k in the A7S III. I'm not sure if that would mean that the 1080p would have to downsample from the 7k in FF mode unless they resort to pixel binning. I'm not technically sound to know what is going on here, but it is a super neat feature either way. You had me reading through the Sony A7 IV menus online lol.
I'm looking to switch from my current GH5 to the A7IV and this video served me well! I do a LOT of sports videography and this is exactly what I needed to see. HOWEVER, one question to ask. I noticed you were in 25FPS, does this work for higher frame rates in FHD like 100/120FPS as well? I do a lot of slow motion when I record full games and that is something I am very curious about. Great video, I even liked it on both my business and personal account it was that good!
Can you confirm it’s only with using ClearImage zoom. Also, can you use some CI zoom like .1x vs going all the way 2x? Does it still sharpen it up? Great video and appreciate the find.
@@JasonMorrisphotocinema so we could just do the 1.1x clear image zoom and still see an improvement if that’s sounds correct. Thank you so much. Love the channel and always trying to utilize my gear more so this is great news
Thanks for the tips, we just got our sony a7iv for our channel and are trying to learn everything we can to improve our channel! Also just subbed. Thanks for sharing.
One thing I would say is I wish they had smoothed out the transition between lens zoom and digital zoom. I also wish they made a wired remote zoom controller that had more granular fine control.
Very informative. I have an inquiry. If I shoot in a medium shot like 35mm. And in post I want to make it from medium to close or extremely close, would it work well or the quality will look bad???????
This is mind blowing. Makes me want the A7iv even more than I did yesterday...which was a lot. How will this affect using 1080p for slow motion? Thanks, Jason!
also been playing with this what is weird is that on A1 where we should be able to do even more its also limited at 1.5x or 2.0x in clearzoom even if we have more pixels to play with BUT... A1+200600*tc2.0*1.5(crop)*2(clearzoom)=1200mm->1800mm and then 1.5 or 2.0 with clearzoom based on 22mp input so downsample 22mp to either 8mp or 2mp for 4k or hd. simulating 2700mm or 3600mm....

The 16 and 30 mm sigma 1.4 on the a7IV don't show cropping in FF mode and crop when you go to apse crop mode, I try them on the a7s3 in FF and it show the vignette and not in a7IV, could you check it if you have apse lens ?
Good to see, thanks for the vid! I'm not sure how others feel, but hearing the background music while you are talking is distracting and irritating IMHO.
Hey Jason I may be wrong but I’m pretty sure you can only shoot 10bit 4:2:2 in 1080p when recording on an external monitor. Without a Ninja V or other options, you’re stuck to the normal 8 bit of the A7iii. Oh I also have a question. With this new finding could we now be shooting crispy 120fps slow motion in clear image zoom?
Weird. Thanks for testing these things! So, if you know you're going to crop in, do it in-camera. I wonder how this translates to the 4k. I mean, many people say shoot 4k "just in case I want to crop in". Would this hold true in 4k?

very good knowledge. thanks jason
Great tip. Im going to start using this
That is pretty interesting!
Mind boggling 🔥🔥🔥
Great video. Very useful information. Thanks!
This is super interesting... I was trying to figure out what is happening here. Is it possibly that Sony Pixel Bins their 1080p when it's FF, but in the APS-C mode it is downsampled from that 4.7k? If I am not mistaken the 1080p is downsampled from 4k in the A7S III. I'm not sure if that would mean that the 1080p would have to downsample from the 7k in FF mode unless they resort to pixel binning. I'm not technically sound to know what is going on here, but it is a super neat feature either way. You had me reading through the Sony A7 IV menus online lol.
I'm looking to switch from my current GH5 to the A7IV and this video served me well! I do a LOT of sports videography and this is exactly what I needed to see. HOWEVER, one question to ask. I noticed you were in 25FPS, does this work for higher frame rates in FHD like 100/120FPS as well? I do a lot of slow motion when I record full games and that is something I am very curious about. Great video, I even liked it on both my business and personal account it was that good!
Not sure about that, but generally, the higher the FPS, the less sharp the image will be. So in 120fps i think it wont be as sharp as 25fps.
You can't do CIZ at 120fps
damn, that FX6 is deadly. What lens do you have on the FX6?
This is really interesting! Thanks a lot for making a very informative video quick and entertaining to watch.
Thank you my friend
Very nice find! Thanks for sharing.
Thank you for watching
Interesting find. Thanks for sharing.
superb!
Can you confirm it’s only with using ClearImage zoom. Also, can you use some CI zoom like .1x vs going all the way 2x? Does it still sharpen it up?
Great video and appreciate the find.
I also want to know. Is it only in 1080p cropped or is it cropped 1080 plus clear image zoom only?
Only seems to be crop and clear image zoom
@@JasonMorrisphotocinema thanks for the reply. I wish it wasn't with the zoom, but good to know.
@@JasonMorrisphotocinema so we could just do the 1.1x clear image zoom and still see an improvement if that’s sounds correct. Thank you so much. Love the channel and always trying to utilize my gear more so this is great news
Brilliant info as always! Thanks!
Thank you Paul
Thanks for the tips, we just got our sony a7iv for our channel and are trying to learn everything we can to improve our channel! Also just subbed. Thanks for sharing.
I have the A7iv and got the Sony 18-105 f4 apsc power zoom lens to do just this for video in 1080 so good to know. Thank you
One thing I would say is I wish they had smoothed out the transition between lens zoom and digital zoom. I also wish they made a wired remote zoom controller that had more granular fine control.
Very informative.
I have an inquiry. If I shoot in a medium shot like 35mm. And in post I want to make it from medium to close or extremely close, would it work well or the quality will look bad???????
Interesting find, would be interesting to see how it compares to XAVC-HS 4K 24p 10 bit 4:2:0 30mbps setting, those files are really small
The 4K still looks better even at the 30mbps. I just tested it
Bro your background is soooo sick
Great discovery! Thanks for sharing
Thank you for. Watching
Jason You should do a comparison on the a7 iii a7s iii and a7iv. As far as clear image zoom.
what about the 1080p aps-c without image zoom. is it just as sharp?
Yes! It's sharper than ff 1080p.
@@user-cf6nb3qz8s what about in 120 fps? does it still maintain the detail?
How do i setup the clear immage zoom on the a6400
This is mind blowing. Makes me want the A7iv even more than I did yesterday...which was a lot. How will this affect using 1080p for slow motion? Thanks, Jason!
You won’t be able to do this for slow motion. Processing is different
@@JasonMorrisphotocinema Thanks, Jason! Keep up the great content!
Hey man,
great tips, thanks for sharing 🙏
Thank you for watching
also been playing with this what is weird is that on A1 where we should be able to do even more its also limited at 1.5x or 2.0x in clearzoom even if we have more pixels to play with BUT... A1+200600*tc2.0*1.5(crop)*2(clearzoom)=1200mm->1800mm and then 1.5 or 2.0 with clearzoom based on 22mp input so downsample 22mp to either 8mp or 2mp for 4k or hd. simulating 2700mm or 3600mm....
So, is the A1 able to do 1.5x Clear Image Zoom in 8K?
@@danielrobertbeaton9357 no 8mp=4k and 2mp=hd i was not sure if any zoom was allowed in 8k so i just tried and answer is no. no clearzoom, digital zoom or crop mode when in 8k recording
Thanks for sharing this Daniel
so just asking out of left field... any good for trying to record the moon at night? a result like 2700mm+ is insane 😂
Is the 1080 just as clean in crop mode only, or does it have to have BOTH crop mode and clear image zoom to get that fidelity?
GUYS THERE IS ONE MORE WAY ON TOP OF THESE TO GET CLOSER, TURN ON ACTIVE STEADY SHOT
wow its awesome!!
Thanks my friend
Does this work for 180p 120fps as well?
Sir, i have a bigg doubt why sony a74 crop when its 60p whats the reason.
how is the HD crop lose on a7c ? does it perform in the same way as it does on a7iv ?
Can you get that 1080p crop in 10bit with 120fps?
What camera rig is it, that you have on the a7 IV in this video?
For Jason. Because you are in crop mode have you seen the deference using a APC lens verses a full frame lens??
Good idea ....but nice to know what is with the autofocus in this "mode" ?
And with the fx30 at HD 240fps and clear image zoom ? Same ?
This is actually a bit mad. We are going to play around with these for sure. Amazing video - just subbed :)
Thank you so much for the effort on this phenomen 🙏Do you know if this also works in ALL Frame rates? 😊 120fps in 1080p?
Could you please tell me what is your camera cage and where can I get it
Thanks
I made a full video about it if you search my page
Nice find! This is very helpful for wedding videographers. Does it only work 1080p 10bit? Or will 8bit achieve the same or similar results?
Hey all. For anyone who is still wondering wether there's a difference between using APS-C mode/clear image zoom in camera VS cropping in post, yes there is, and it does matter.
When you shoot on the A7III for example you are reading off a 24mp sensor, downsampling from roughly 6K down to 4K. 4K resolution works out at 8.3 Megapixels, this means the camera has plenty of room to crop in from the 24mp sensor readout PRIOR to writing the file to your memory card before you'll get close to hitting that 8.3MP limit of 4K. That is how there is next to no difference in sharpness when using APS-C mode or Clear image zoom; it's because no matter if you use the full sensor read-out or one of the crop features, the resolution of the actual video file written to your SD card will be the same, 3840x2160.
However if you record the full sensor readout image and then try to crop in post to achieve the same scaling, you're not cropping from the original full sensor readout like how your camera can do internally, you're simply scaling up that 8.3mp/3840x2160 of resolution (your 4K file). This means you will IMMEDIATELY start to lose resolution. So yes, it matters.
Nicely explained, thank you!
Very cool! Gotta try this on my a7iv and Tamron 35-150. So it would essentially get a reach of 450 at f2.8!
Hi I have question about a7 IV zebras setup. I want to shoot cooking videos. Like Googa Food's can You please help me what need to be the zebra setup? Because a think the best will be manual focus instead auto. But I can't figure out the zebras. Thanks and regards from Poland 🇵🇱
HOLY wow That is insane I didnt even know
a7vi and a7cii should have the same sensors, right? On my a7cii, this is oddly not applicable.
looking jacked Jason, I'd listen to you just because of that.
Does this apply to the A7RV?
I am not sure. I didn't test this
Gh5 and a7iii i noticed.. very good imago full HD! Like it morebthan 4k
Hi man! great Videos! This mean that you can benefit from this trick also in 120 fps? and get that slomo in this 'crispy' 1080p footage??
Thanks!!
Great clip. Thanks.
Thank you
Do you know if it works with 7siii?
The 16 and 30 mm sigma 1.4 on the a7IV don't show cropping in FF mode and crop when you go to apse crop mode, I try them on the a7s3 in FF and it show the vignette and not in a7IV, could you check it if you have apse lens ?
what compact lens would you recommend for this camera? i’m looking something small to fit in sling bag along with other things
I was super into this, until I tried it on my 1080p 120fps mode and the camera told me no because of 120fps. It is super cool though.
Af still works in clear image zoom?
How do you like the Meike FF cine lenses? Are they objectively good (disregarding the price)?
WOw! who knew?! thanks
Good to see, thanks for the vid! I'm not sure how others feel, but hearing the background music while you are talking is distracting and irritating IMHO.
Hey Jason I may be wrong but I’m pretty sure you can only shoot 10bit 4:2:2 in 1080p when recording on an external monitor. Without a Ninja V or other options, you’re stuck to the normal 8 bit of the A7iii. Oh I also have a question. With this new finding could we now be shooting crispy 120fps slow motion in clear image zoom?
Nope you can shoot 10bit in camera.
Weird. Thanks for testing these things!
So, if you know you're going to crop in, do it in-camera. I wonder how this translates to the 4k. I mean, many people say shoot 4k "just in case I want to crop in".
Would this hold true in 4k?
That's what I was thinking, too...
In my opinion filming in 4k is better. More room to play in post for sure. I’m just glad Sony gave 10 but Color to those who film 1080p
nice tuto. However i have read that 4K 4:2:0 is sharper and takes less MB for 30sec footage than HD, even cropped. what do you think ?
what does "1:1 readout of a small part of the sensor" mean?
It means the sensor is read at a 1:1 readout of pixels. No line skipping or binning pixels. Every pixel is being used
with clear image zoom, don't you lose eye auto focus on the a7iv ? on the a6600, Its not available.
