If you're using the "VideoIntroScreen"-Script for playing your logoanimation after game-start you might run into this problem:
The videoplayback is very bright and you loose a lot of detail in the brighter areas of your video.

Here is an example:

To solve this problem, edit the VideoIntroScreen.cs-file (Assets->UFE->Scripts->UI->Templates):

Change this (line 100):

 guiTexture.color = Color.white;

to

 guiTexture.color = Color.gray;

Now the video should be playing normally. Maybe there is a better solution to remove all color-attributes from the videotexture/material, but that "dirty" solution worked for me
