"video-rgb" vs "pc-rgb"

knutinh · 2006-08-14, 13:57

What is the default behaviour in MP for material that is encoded as "video rgb", ie black is 16, while white is 235 vs the regular pc-standard where black is 0 and white is 255?

I think that for some codec/revision combinations, my videos will occasionally appear grey, while for other combinations they will be solid contrast.

I am afraid to compensate using the contrast of my video card as that will render the GUI, my photos etc wrong.

regards

Can you just tweak it in the video codec?

But is there some meta-information in the video-stream telling if it is one or the other? Is it possible to tell any of the codecs to convert to pc-rgb if needed, but do nothing else?
