Magic Music Visuals

I found the solution, the problem was with VLC player in combination with nvidia drivers.
If you have the same problem, here is the fix:

Hi,

When I render a video to mp4, a black #000000 screen turns into gray-ish #101010.
This is very inconvenient! How do I fix this?

Thanks,

Tom
