I was wondering if it would be possible for us to choose or to totally omit the preview image for the videos when we choose them.
In my case, for example, I would rather have the preview capture any frame at 0:00 of the video even if it's just a black/white screen because I find that the preview as it is now can spoil the video I'm about to watch.
This is a huge problem especially when I'm watching recorded matches since a frame from 10 or more minutes forward in the match can clearly show what was the score at that time and ruin the whole experience of watching a football/soccer (or any sports) match that you couldn't watch live and that you are trying to watch like it is actually live.
It happened twice to know that my team or the opposite team was one goal ahead at a particular moment of the first half because of the video preview...
The same thing is of course valid for some tv series where sometimes things happen during the first minutes of an episode.
