Remove timecode track from video file
When exporting a video from DaVinci Resolve to a QuickTime mov container you will add a timecode (tmcd) track to the file. When checking with ffprobe on the video, there will be a stream looking like this:
Stream #0:2(und): Data: none (tmcd / 0x64636D74), 0 kb/s (default)
This is can give issues as some applications, at least on Android, won't be able to open the file and will just complain that something is wrong with the video file.
