    Based on John’s theory you might be able to counteract the contrast effect by adding a Brightness/Contrast Effect with the settings -8,6 contrast, -1 brightness, Use Legacy Mode box checked. While not an answer as to why the shift is happening, maybe some such workaround will allow you to get through the current job and then research the matter further when not under a deadline.

    It is my understanding that the contrast problem shows up upon import, suggesting that something related to import is interpreting the file incorrectly. It sounds a bit like the “setup / no setup” problem from a few years ago, but I thought that was related to quicktime and had been resolved.

    Photoshop has that snakepit of “profiles” but I don’t remember anything similar in AE. Other than a codec or color management settings, what else could change the interpretation of a file?

    Never! But I try not to work on the weekends.

    As John mentioned last week, the problem here seems to be an issue of video levels versus data levels [link]. With color management on, interpreting the original as HDTV (Rec. 709) 16-235 makes it an exact match for the Ae render interpreted as HDTV (Rec. 709).

    Apparently, levels in Vegas is a common source of confusion [link].
