Alpha channel lags behind video #44

Open RenaKunisaki opened 1 year ago

RenaKunisaki commented 1 year ago

With some videos, the generated alpha channel is out of sync with the image. Example in this image. 2022-12-11-210847_1920x1080_scrot You can see at the legs and head, the alpha mask is in the shape it should have been a handful of frames ago.

Command used: ~/.local/bin/backgroundremover -i '568925567_3AXGeHborlS4Ew02v_Source.mp4' -tv -o test.mov and mpv test.mov - so far only mpv seems able to play these back at all.

I've been able to convert the affected videos to more "common" formats filling in the background with a solid color, and it still has the same issue. So it's not a problem with mpv.

Seems like this is an issue with the length of the alpha video itself I noticed that the original video was shorter by like 1 second or so so I changed the speed of the alpha video in premiere pro to match the original video and that seemed to fixed it
