prores 4444 level shifts
I’m exporting motion graphics from motion as QT prores 4444 files. If I import them into FC 7, add it to a sequence, match frame somewhere in the middle, make a still from the resulting match and insert it into the motion graphic, the level on the still shifts.
If I export the motion graphic using the dv codec, no shift. Whats up with that?

Dan,
I have no idea, but you left out an important piece of info above. What are the sequence settings you’re dropping the ProRes graphic into?

DV is a superior codec to ProRes 4444…… jk
When you export to ProRes 4444, try changing the gamma correction on “none”.

I have just arrived to Prores 444, so no experience, but the compressor have a Gamma option.
Try both ways.

It’s a standard def dv sequence

I’ll try that and report back.

Changing gamma correction from automatic to none makes the level shift worse.

Dan,
My inclination is always to look to DV compression as the culprit. If you’re done editing, try changing the compressor in Sequence>>Settings to ProRes, then re-render, then grab you still and see if there’s a color shift.
Do you see where I’m going?

Hmm. ProRes 444 can be either YUV or RGB….perhaps some sort of conversion is not happening when creating the still from the original (which may be RGB coming out of Motion)

Yes, but we don’t know in which circumstances.
Same about 12b.
When and how?
