Comment (by alwinramirus):

 The ass files just contains a draw command to draw a green rectangle on
 the left side with the color (0, 245, 0). This is the same color as the
 video. In every media player this results in just green being displayed.
 Using ffmpeg (see out.mp4) there are two shades of green. Probably due to
 using the incorect matrix.
