This seems to be a bug in WMF's YUV-to-RGB conversion. We can work around this by using our own pixel conversion shader.
1) Open and play a WMV2 encoded video in the Editor, i.e. \\Z2448\Share\Media Files\FromCommunity\Alonexsi\BrightnessIssue2.wmv
Notice that the brightness is too high
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-35529 in the post.
