Description Peter 2016-01-24 14:16:48 UTC
If the movit library is enabled, not only does the playback window show a brightened video, but the actual rendered video is noticeably brighter than the source, and a video rendered without movit.

You can see clips at the URL.

Reproducible: Always

Steps to Reproduce:
1. Turn on movit
2. Play an imported clip - note bright playback 
3. Render a clip - note bright rendered video

Actual Results:  
Bright video

Expected Results:  
Video that looks the same, yo.

The render process seems to add a glsl.=1 to the script for rendering which results in bright video - but I'm assuming this is needed for GPU effects to work.

I thought this might be a YUV levels issue, but it doesn't look like the usual levels recognition stuff.

This is with the amd open-source drivers.

Let me know what other details you might need.
