Hmmm... Not sure whether to post this question here or in the Cineform forum, but I guess I'll start here.

I sometimes get a bit lost on this topic, so I'm really just looking for how to set this up correctly in Vegas. Let's say I shoot video on a 5D2, then run the mov files through NeoScene to transcode to Cineform. (Also note that 100% of my distribution is web based, e.g. Blip, Exposure Room, YouTube).

When I drop these Cineform files onto the Vegas timeline:

1. Do I still need to drop a Computer or Studio RGB fx onto the clips to get the right levels?
2. In my scope settings, do I click the IRE checkbox or not?
3. In my scope settings, do I check the 16-235 box?

What's interesting is that I've been using 0 contrast on my picture profile in the 5D2 to help flatten the image, but with NeoScene, it's already so flat (which is good I know), that it makes me want to start cranking up the contrast in camera again.

Any thoughts, help, appreciated...

A Cineform HD Link conversion to Cineform AVI corrects two things in the Canon footage:

1/ It slows the footage down slightly from 30fps to the industry standard 29.97.

2/ It rescales the colors (at 10bit precision) from cRGB to sRGB. Instead of blacks being 0 and whites being 256 it scales them down to the industry standard of being between 15 black and 235 white.

Yeah, a lot of the time you won't need to color correct at all anymore if you were careful during shooting.
