  • Cross fading 2 videos segments using ffmpeg when number of frames are not known before hand

    5 avril 2016, par Hero Roma

    I am a newbie trying to cross fade 2 videos using ffmpeg and the stackoverflow answer. But in my case I do not know the length of the video or the number of the frames. I want to start the fade out in the first video in the last 5 frames and fade in the first 5 frames. I am able to do the fade in on the second video but I cannot figure out how to do the fade out in the last 5 frames when I don’t know the duration or the number of frames.

    The "-i" option is supposed to be able to extract that information but I cant seem to pipe it to the next block there.

    ffmpeg -i 1.mp4 -i 2.mp4 -f lavfi -i color=black -filter_complex \
    
"[0:v]format=pix_fmts=yuva420p,fade=t=out:st=4:d=1:alpha=1,setpts=PTS-STARTPTS[va0];\
