    Dear All

    I have a many video files that I want to group and merge into a single videos according to what it is filmed. I know how to merge videos by cli using mkvmerge.

    However I would also like to:
    • add a fade transition between videos
    • at the beginning of each video I would like to put some description on the center-bottom which has to stay on for some time (like 5seconds or so)

    there is any CLI solution to do that?

    Regards
    Pierre

    Using the code you've linked above, that is
    Code:
    ffmpeg -i 01.mkv -i 02.mkv -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];[1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+4/TB[va1]; [2:v]scale=960x720,trim=duration=9[over]; [over][va0]overlay[over1]; [over1][va1]overlay=format=yuv420[outv]"  -vcodec libx264 -map [outv] out.mkv

    I get this:

    Code:
    Unrecognized option 'filter_complex'
    Failed to set value '[0:v]format=pix_fmts=yuva420p,fade=t=out:st=4:d=1:alpha=1,setpts=PTS-STARTPTS[va0];[1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+4/TB[va1];[2:v]scale=960x720,trim=duration=9[over];[over][va0]overlay[over1];[over1][va1]overlay=format=yuv420[outv]' for option 'filter_complex'
    Thanks
