    C300: Premiere 15.2 altering luminance of 10-bit files. Can you confirm?

    Can someone confirm this? I think my 10-bit 422 MP4s (C70 & R6) are having their luminance messed up in Premiere 15.2.0 (build 35).

    I believe Canon log 1 & 3 should max out the super-whites at 110 IRE, and the black-level should crater at about 7 IRE or so. That's how it looked in Premiere v15.0 and 15.1 (I installed older versions to verify and take screen shots).

    Now the whites are clipping at 100 IRE and the black is above 10 IRE (I think it's just a mapping issue--doesn't seem anything is clipped, just bumped up and squished on the waveform monitor).

    Someone at adobe said they'd look into it. But can you fellows confirm what I've said? Screen shot attached.

        Drummond, I don't know what I'm talking about, but that is exactly what it looks like to me. Sorry you're getting no expert replies. I think everyone has finally gone back to work after a year off. Have you tried asking on a Premiere board?

          another option: some don't use Premiere.
