> use "RGB" color space to make a Quicktime Movie
Sorry, but that is a VERY bad idea.
It will stretch the 16-235 values in your footage to 0-255, crushing all
blacks below 16, and clipping all whites above 235.
You will have eliminated all that white details prior to editing, let alone
color correction.
If you export as 601/709, the levels of the original remain untouched. 0
remains 0, 12, remains 12, 16 remains 16, 235 remains 235, 245 remains 245,
etc.
Honestly.
If you export as RGB, you crush/clip and then stretch (0 becomes 16, 12
becomes 16, 12 becomes 16, 16 remains 16, 235 remains 235, 245 becomes 245,
etc.)
IMHO, you only export in RGB when exporting a deliverable that is meant for
viewing on computer monitors, for nothing else. If you are working in video
color space and will be working in video color space and are delivering on
video color space, the RGB export buttons should remain unchecked the entire
route.
