I’m trying to create a simple video-dj app in Python (gui framework undecided).

I’d like to be able to crossfade from one playing video into the next video, or fade to a still image.

I’ve looked at Pyglet, VideoGear, Kivy and Pygame, but have been unable to find anything obvious about how to control the alpha or opacity of a video player.

Is there any established (and ideally low-impact, as I’d like to do this on low-end machines) technique to achieving this without frame-by-frame manipulation? I was thinking of creating 2 video players or even 2 complete windows and fading one out while the other fades in… Is this possible?

Thank you 🙂
