Bob, elsewhere on the Web you said:

"Going to 108% simply means more of the range of digital values are used. For certain it can get clipped down the track however it's simple enough to use a curve to map the 100% to 108% values into the legal range.

What would be the proper procedure to deal with in Vegas?

Thank you!

If you simply want to bring the superwhites into legal range then I use a custom Color Curve. Glenn has it all documented here including a link to a sample project you can download and then save the curves as presets. One of those will do exactly what I'm talking about, it's fairly obvious looking on the scope what it's doing.

If you're using the cinegamma / hypergamma settings in the camera the same would apply if you wanted to simply avoid them being clipped. You need to be a tad careful with these gamma curves in the camera, if there's anything other than white going over 100% you can get problems with banding.
As for doing anything really creative with those superwhites recorded using those Cinegamma curves I'm not that certain how to do that. My gut feeling is you'd probably want to start by recording in 10bit however recording HD at 10bit is not cheap.

Bob.
