One aspect I omitted from these tests is green screens and keying. I'm not very experienced with it and don't even own one anymore. But the consensus is that 4:2:2 will give you a notable improvement in your ability to key over 4:2:0. So if that's what you plan to do a lot of, you'll probably find a more significant advantage to the external on the Sony. Thanks for watching! 😃👍

Gerald Undone This is a very important omission. If you want to break chroma sub sampling the examples in this video are not the way to do it. You need to shoot strong primary colors with sharp contrast between them. You will quickly see the edges become jagged and blocky. More color resolution will direct equal less of those artifacts. When keying out blue or green screen it’s very obvious.

I do green screening and from my tests/what I think I know, your going to want as much info as you can to work with. But given the choice between 4:2:2 or higher resolution, the resolution has more of an effect. More pixels density, any problems you have become smaller. But all in all, the more you have the better. Ideally 4:4:4 8k would be best!

I wish Gerald made videos focused on the DP and filmmaking aspect. For example; How to light a scene, how colors and lighting decisions complement the subject and the environment, Tips and tricks to get the audience's attention on a specific object or aspect of the scene. He is incredibly technical in all of his videos, and I love that...but I wish he could work a little bit more towards the artistic use of cameras and other gear. I'm sure he'd be great at those as well. His genius can't go unnoticed, and it makes him a professor on everything he reads and searches about.

Dorian Bury - Wow dude...! Glad I saw your post.😧

To give a slightly more straightforward explanation of chroma subsampling: 4:4:4 - Full colour resolution 4:2:2 - Full vertical colour resolution, half horizontal colour resolution 4:2:0 - Half colour resolution So if you're shooting at 2160p with 4:2:0, the luma channel will be at full res, but the chroma channels will be in 1080p. In 4K and higher, the difference is usually pretty subtle unless you're zooming in to 300% or doing some sort of keying. The major difference comes more from codecs with less chroma subsampling also usually using higher bit rate All-I compression and having 10bit or higher bit depth. In the case in this video, the lower bit rate and interframe compression on the internal codec is the major visual difference.

Actually 4.2.0 is a quarter of full colour resolution When ntsc was designed it was decided to have each colour at one quarter of the luminance resolution to reduce bandwidth This was referred to as 4.1.1 4 being luminance 1 being red 1 being blue The pal system had the same specification but achieved it differently and to prevent any confusion called it 4.2.0 I.e. added the 2 ones together If you think about it 4.2.0 is technically nonsense Red would be 2 and blue 0 A tv system would not work with blue equal to 0 So 4.2.0 was purely done to differentiate it from 4.1.1 A Tv design engineer

@@johnwilcox7826 As far as i have understood, the difference between NTSC DV 4:1:1 and PAL DV 4:2:0 is that 4:1:1 has 1/4 resolution horizontally, but full vertical resolution. On 4:2:0, resolution is halved both horizontally and vertically. In other words, both have 1/4 color resolution but you could think 4:1:1 uses a horizontal squeeze to 25% to accomplish this, where 4:2:0 uses 50% scaling in both axes. 4:4:4 xxxx xxxx xxxx xxxx 4:2:2 x.x. x.x. x.x. x.x. 4:1:1 x... x... x... x... 4:2:0 x.x. .... x.x. .... The 4:1:1 and 4:2:0 naming comes from using the eight-pixel block for the naming as seen in the video. In 4:1:1, both the top and bottom rows only have one color sample, and as Gerald explained, in 4:2:2 both rows have two samples and in 4:2:0 top row has two samples that are copied to the bottom row, which has zero unique color samples. Visually, the two look slightly different. 4:2:0 looks better for progressive and nonmoving images, but AFAIK may cause motion problems with interlaced footage, as the 2nd field actually used copied color information from the 1st field. 4:1:1 looks mushier, but as both fields have unique color information, there are no issues with interlacing.

@@johnwilcox7826 If 4:1:1 meant luma:red:blue as you suggest that would make a lot of sense, but for historical reasons it isn't how it actually works. (Gerald has it correct.) It dates back to the way standard definition analog video was converted to digital in ancient times. Analog scan lines within a video field were digitized in pairs (which makes sense if you dig into the details of analog television), and the three numbers refer to a multiple of a base sampling frequency, in order: luma sampling on every line : chroma sampling on the upper line : chroma sampling on the lower line. In 4:1:1, for example, luma is sampled at 4 times the base frequency on every line and chroma at the base frequency on every line. In 4:2:0 chroma was sampled at twice the base frequency on the upper line of each pair (within a field) and not at all in the second line. NTSC actually used both conventions. Sony DVCAM, for example, used 4:1:1 for NTSC, but Panasonic's system used 4:2:0. NTSC DVDs are all 4:2:0. (PAL/SECAM is indeed pretty much 4:2:2 across the board, except for Brazil's PAL-M which is basically NTSC with PAL color in the broadcast signal). While I'm quibbling, resolution differences aren't as simple as a ratio of total pixels (no matter what marketing departments think) and in traditional television work vertical and horizontal resolution are defined and measure differently. In analog SD, for example, (limiting) vertical resolution is a function of the number of scan lines and horizontal is a function of bandwidth (and usually specified as the number of alternating black and white lines that can be distinguished across a width of the picture equal to the height).

Hi Gerald, thank you so much for all your hard work demonstrating the difference between 420 and 422, I don't really do video but each new camera boasts further enhancements and I like to know something about the relative merits of the various options. It has always been clear to me the the manufacturers have a tendency to exaggerate the advantages that their latest product offers, it seems it is only people like you who can tell us how it really is in the real world of actually using them!. Thanks again, Cheers, Richard.

The differences are just not meaningful for the work we do - and why I think the recorder-only, 40% less expensive Atomos Shinobi makes far more sense for most hybrid shooters than the Ninja V. With this written, I look forward to the day when you compare the Nikon Z6 12-bit ProRes RAW on the Ninja V to the 8-bit internal. At least in theory, THAT will be VERY interesting.

Thanks for this video, just what I was looking for, answered the questions I had about getting an external recorder.

very informative, thank u! I Really feel the XT-3 gives a huge upgrade for grading compared to the already excellent GH5. At first i was worried the 4:2:0 would negate the benefits of the 10 bit, but in 4k50 and 1080p 100fps its such a huge upgrade. And even in FLOG, where you increase the risk for banding simply by the fact, that you have to expand footage in post thats compressed. Im very impressed by the results im getting with the 4:2:0 10 bit. Now i think i understand a bit better why that could be...

Fantastic video. I have had that exact question. I have an A6500, but now I know that I don't have to upgrade right away. Thank you!

I've done similar tests myself. When it does make a difference to go with the atomos is when you have skies in your shots and you want to add some dramatic flair to the by bumping up the contrast with a power window. Overcast skies can be very low contrast and it takes a very strong curve to make them look interesting.

Excellent comparisons! I have a BMVA which I bought mainly to have redundant recording for my clients from my Sony EX-1R camcorders.. I also have compared the resulting video and see very little difference in the video. The big deal is that the higher bitrate recordings on the BMVA just result in larger files which of course require more processing by my edit computers.I am about to launch a project funded by the NIH and intend to use the BMVA at either Pro Res or DNx45, but once again, mostly as redundancy of the materials..

I needed this. Xt3 just came in the mail today.

This video was a godsend... SERIOUSLY! for the past week i have been stressing over whether or not i should get one. All i have gathered from most videos is that i should get one if i deliver professional work and need better codecs for better quality. Now i finally have a clear idea of what i would be getting myself into.

Nice video. Would have loved to see higher ISO/gain tests. We know that Sony applies two stages of noise reduction on most of their cameras. The first stage is the sensor readout cleanup. The second stage happens in the XAVC H.264 encoder chip itself. In theory, the higher gain/ISO you pick, the more and noise reduction is applied. Also, in theory, the HDMI will only have the stage 1 noise reduction applied and not the second XAVC hit. So,....at higher gain, the HDMI "should" have more and more noise but also LESS noise reduction artifacts and possibly more detail. Would be interesting to find out.

This reminds me of some music production videos comparing subtle effects like compression to a clean audio track. I think it ultimately comes down to your preferred workflow and what your eyes (or ears) are telling you.

Very useful information :) If the differences only are on a pixel level, it really does not seem worth it to invest solely for image quality. Having a small spiffy external screen with other really nice features might still be worth it though.

Hey Gerald! A good test for this in a real-world case is selecting colors with the HSL selector in DaVinci Resolve. Lower subsamplings will be blockier and have some gaps within the same color.

Good comparison video! I think the blockiness comes from the different compression not subsampling..
