4:4:4 RGB footage not legal
I am rendering out a text crawl in After Effects CS3. I am sourcing footage that I captured from a 4:4:4 HDCAMSR tape as 10-bit RGB. At the time of capture the footage was legal but after my render in After Effects the footage goes out of range. I am not adding any effects to the footage I am merely adding a text crawl. The footage does appear to be legal when I set the Kona card to output 4:2:2 though. I have a Kona 3.

Did you set up your color management for the project under project settings? And was the clip you captured interpreted with the correct color management in the interpretation menu?

Are you adding a 100% white text?
If so reduce the white.
Are you exporting AJA RGB Full Range or SMPTE?Mac OX 10.5.2-FC 6.02-QT 7.4.1

When I bring in the Quicktime files into After Effects they do not have a profile. I found that using the sRGB IEC1966-2.1 profile did not change the color of my video but that seems to only happen when the Kona card is outputting 4:2:2 video. I thought I should be using the Rec. 709 colorspace but that seems to cause a shift in my colors.
I am outputting full range and I have my title crawl at 90%.

I think that if you are going back to FC you should be exporting SMTPE instead of Full Range.
60-940 are the legal Black and White points in 10b footage. same than 16-235 for 8b footage.
Exporting as Full range you are bringing your whites at 1024.Mac OX 10.5.2-FC 6.02-QT 7.4.1

I’ll give it a try again. I thought I did that to no avail but I will double check. I remember the footage coming out darker. The full range looks fine on the 4:2:2 output from Final Cut Pro.
