First of all, I know with budget I shouldn't use 5D to shoot chroma keying footage. It's h264 compression not enough chroma sampling...I can have F3 I can have Alexa...yes.
But now i'm using 5D and going to shoot chroma key, and ran some test.
As technicolor picture style being too good for future post,
I tried it with chorma key,
and find it being much more blocky than normal.
Anyone familiar with chroma keying with 5D?
Or I just need a professional VFX artist to help?
