The Clip was filmed with a Sony a7s and recorded using an Atomos Sumo with ProRes422 HQ (Planar 4:2:2 YUV 10-bit LUV, Rec.709).
When I watch the Clip on the Sumo or using a video player like VLC, for example, the picture looks fine.

When I import the file into PremierePro the colors and exposure are completely off: The picture is way over exposed. This problem occured in the versions 14.5 and 15.0.
It did not occure in version 13.1 though (using the same clip).
