4:4:4 vs. 4:2:2 vs. 4:2:0

What's the difference between 420, 422, and 444? What does 4:2:0, 4:2:2, and 4:4:4 mean? Do I need 420, 422, or 444 on my camera? Find all your answers here!

The unique luminance factor was really insightful. Also appreciated the realistic example of the green screen rather than having eight wildly different pixels in the pallet.

You nailed the topic and explained it really well. Thank you

[samsol]

That was insanely well explained. Thanks so much for sharing this knowledge

Great Video!!! WoW you are nice, direct and straight in to the point without and flubber and you got the educational part DIALED IN FAST = THANK YOU

I never understood this before. I just assumed the higher the #s the better. But bigger isn't always better. The visual animations were helpful. Great job barking up another helpful video.

This video is by far the best explanation on the color encoding that I've seen. Thank you!!

[scanspeak]

Finally someone who explains things clearly in a way even I can understand. Cheers

Best video I've seen on the topic so far, well done.

[blockbusterlatefees]

Dude thank you. This was driving me insane. 4:2:2 for green screen work. 4:2:0 for everything else.

Video in 4:2:2 won't play on my phone. But video in 4:2:0 will. Strange but at least I know the difference!

[john-wiggains]

I’ve always been so confused by this concept but you made that so plain and simple! Thank you!!
Good to know it’s useful for green screen!

[wongowonga]

Well done sir, this is easily the best explanation I have ever seen on this topic. Brilliant video, thank you.

[DeejayJeanP]

Jeez, never saw 6 mins fly by this fast - great explanation !

[IsawUupThere]

I did not expect such a great explanation on this topic from a man talking to me in ungraded log profile! Very helpful.

[Bill.Pearson]

This is as clear as any example I've seen, and far better samples of each displayed, too.

[rped]

This video is great and, as other people commented, goes straight to the point. Good job!

[hannahblair]

Fascinating! Very helpful. Thanks for this video!

Its not a block of 8 pixels. Those 8 color blocks are just theoretical & illustrative representation of the ratios involved between luminance & the two color sub-sampling (for red & blue) during encoding & compression.

[glyakk]

Great explination, I have been trying to wrap my mind around this and now I have a much better mental model.

[jordan-mnyy]

i was literally using 444 for 10 yrs b4 i used a pc on a tv. This event reminded me to use 422 for tv. And realized its superior so the upgrade to my gaming pc monitor was a downgrade in bit color.

[soffici]

Thank you. De mystified this very nicely
Just one question: when you say "8 pixels" do you mean "8 groups of 4 pixels each"?
If not, I'm a bit confused about how a single pixel can have chroma information, if it sits behind a Bayer matrix filter
Also, but this is mostly just curiosity, why 8 pixels?
Feel free to DM me if you don't want to go too deep in the rabbit hole in the comment section
Thanks a lot
