Ask Alex - The 411 on 4:4:4

Does the term "Chroma Subsampling" frighten you? Are you unsure what the difference is between 4:4:4, 4:2:2 and 4:2:0? Watch this video, and be mystified no more!

sooo helpful :)

thanks a lot !!!

isn't there a single dslr with 4:2:2 in video mode ??

[5DFilmSchool]

@SOEINEGAUDI The only way to get 4:2:2 out of a DSLR is to use a standalone video recorder like the Atomos Ninja.

easily the best basic explanation of this I have yet seen (and I have done a lot of searching)

Thanks Alex!

@outdevo @cgxphoto Thanks for the kind words ... I'm very glad that you liked the video!

Very good explanation. But could you tell me if I'm right or wrong if I say that the 4:2:0 in the first line takes 2 samples of blue and from the second line takes 2 samples of red. This is what really is 4:2:0 subsampling? I mean, it takes half the U info and 0V info from the first line and 0u info and half V from the second line? Am I right?

Very well explained and illustrated. Thank you for taking the time to explained this technology and for sharing your knowledge.

Hi Alex

Great tutorial. Thanks. :)

[SOEINEGAUDI]

@5DFilmSchool Thank you ! This seems like a great concept, but how can i know

if the dslr truly puts out 4:2:2 ? couldn't it be that the hdmi output already is compressed ?
