FFmpeg : Trying to fade out first and later fade back in doesn't work [duplicate]
6 septembre 2023, par Paul SWhile I just became a registered user on the site, I've been utilizing Stack Overflow for years, virtually always being able to find solutions to problems I've encountered. Unfortunately, not this time ; I have encountered a problem with the ffmpeg video fade filter. There are lots of previously proposed issues along with their solutions, but none (that I can find) that address a twist that I have.


Most questions ask, "how do I fade in", or "how do I fade out", and "how do I fade in at the beginning and fade out at the end." If I want to fade in and later fade out, my below code works just fine.


ffmpeg -ss 00.0 -accurate_seek -to 15.0 -i My.Test.File.mkv -c:v h264 -vf fade=t=in:st=0:d=2,fade=t=out:st=13:d=2 -b:v 825k -s 1280x720 -r 29.97 -c:a aac -ar 44100 -ac 2 -b:a 96k output.mp4



However, I actually want to fade out somewhere in the middle, and then fade back in shortly after, and that doesn't seem to work. I structured the ffmpeg command as so :


ffmpeg -ss 00.0 -accurate_seek -to 15.0 -i My.Test.File.mkv -c:v h264 -vf fade=t=out:st=6:d=2,fade=t=in:st=9:d=2 -b:v 825k -s 1280x720 -r 29.97 -c:a aac -ar 44100 -ac 2 -b:a 96k output.mp4



This fails and yields a completely blank video. I've also tried some -filter_complex variations, but get similar results ; fading in and later fading out works, but fading out and later fading in does not.


I'm using the latest ffmpeg windows version on Windows 10. I would have attached a sample video file but I'm seeing how to do that. It is not the original video file that started my issue, but it does duplicate the issue. Not sure what other info might help in coming up with a solution. Thoughts ?

avfilter/vf_bwdif_cuda : CUDA accelerated bwdif deinterlacer
30 août 2019, par Philip Langdaleavfilter/vf_bwdif_cuda : CUDA accelerated bwdif deinterlacer
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
