Having gamma problems in Premiere? Solve the gamma shift with a simple task!

Hey folks! i just stumbled over a post in the F35 Thread... So for all of you having Problems with Gamma Shifts with some codecs:

Your highlight info is still there in Premiere, you just have to remap your colors. Put a Fast Color Corrector (I'm pretty sure that's it) onto the footage. Leave Input Levels at 0-255, but change Output Levels to 16-235. That should bring the highlights and shadow details back within broadcast legal levels, dropping your contrast and removing clipping. This works on almost all gamma-shifted footage that QuickTime messes up, as well as AVCHD footage with full range color space (like is possible with the FS100).

I just tried that simple task and it works great, all my FS700's footage now shows full DR

I'm not that much into that bitdepth and color information thing, but does that task kind of "squeeze" the color information in a smaller room? Would be greatly appreciated if anyone could elaborate this...

Thanks to CaptainSKA!!

I had similar issues recently where I thought QuickTime was actually adding contrast and darkening my footage by shifting my signal around but then discovered that actually, certain formats, codecs and bit-depths can store video data signals differently. For example a 8-bit QT file tends to store a signal very "legally" whereas some 10-bit formats, or if you go DPX or EXR will extend to cover the full data range. I say SOME 10-bit formats because even then there are some differences depending what codec is used.

If anyone is curious more about my experience and findings are posted here: http://www.dvxuser.com/V6/showthread.php?309606-YUV-or-ProRes-darken-my-slog2-footage/page2 - I learned a lot from reading the Davinci Resolve manual oddly enough.
