I am in the AFF website. I have made videos of me cooking a steak and me working out with my rings. After adjusting the video with ShotCut, AFF says the audio plays but not the video. I my videos normally play everywhere just fine.
I have played my videos in the following places:
YouTube
VLC
Firefox
Chrome
Whatever that Microsoft default player is called
Seems to work everywhere as an MP4.
Any ideas?
