Automask tracking works badly on any successive clip if i load this clip as first.
This is a very strange issue, happened often to me because i'm doing a lot of automask tests and slow motion tests (that are without audio)..
if i place as a first clip "slow.mp4" or any other slow motion clip without audio on project bin i'm no able anymore to use automask tracking on any other videos. (and if i use the automask on slow.mp4 i've a tracking just of first frames)
this is the video (download link) http://www.wcn.it/slow.mp4
and this is what happens:
the 2nd clip can be anything.. but i'm supposing that the lack of audio track is the issue. (or maybe that the first video is 720 .. and the 2nd one 1080? )
if i not accept the project changes.. everything works fine:
