Comment (by Michael Koch):
With the ski.mkv video the no-data borders are also filled with the color
of the border of the data area. That can be shown by drawing a red border
around the frame, before applying vidstabtransform=crop=black. Black
borders appear only when the shift is very large.
ffmpeg -i ski.mkv -lavfi vidstabdetect -y dummy.mp4
ffmpeg -i ski.mkv -lavfi
drawbox=w=iw:h=ih:c=red,vidstabtransform=crop=black:optzoom=0 -y out.mp4
