Flickering videos #22

Closed alexarje closed 4 years ago

I just ran a full analysis on all the three videos I have uploaded in the test_videos folder. Most things work well, but I see that all the exported videos behave strangely. On OSX the output videos flicker between green and normal.

and on Windows I get this type of scrambled video when playing in the media player:

The files play ok in VLC, but still there appears to be something strange with the codec. Perhaps we should just switch to regular .mp4 file output with h264 compression. That is more future-proof than .mov anyways, I think.

Indeed, this is something we also experienced but forgot to make an issue out of.

balintlaczko commented 4 years ago

Yes, indeed. Let's switch to .mp4 and h264.

aleksati commented 4 years ago

Implemented this now. The flickering is gone. However, it would be nice to do some testing on Windows and other OSes as well before closing this issue.

Well done, the gibberish video is indeed gone on Windows too! Good job!
