  • Is it possible to merge 3 videos with ffmpeg by -f concat and crossfade without video content

    10 août 2019, par user3792705

    I want to merge 3 .mov files quickly without losing any resolution. I want to be able to distinguish the 3 pieces of videos after merge.

    "ffmpeg -f concat" does not lose resolution and quick without crossfade.

    But, I can’t distinguish 3 videos.

    As far as I know ffmpeg filter can be used add crossfade, but it have to use video start/end content to do the merger, which might involve transcoding. It won’t be fast compared with ’concat’, which won’t do transcoding, but simply copying.

    Here is the content (ffmpeg -i video.mov) of one of 3 videos :

    If I don’t care about crossfade with video content, just some ’nice’ black screen in between (It would be nice I add some text, like date + time on the black screen) is good enough for me. Is it possible to do ’concat’ and simple crossfade without video ’content’ ?

  • How can I use FFMPEG in my discord bot thats on github

    21 septembre 2019, par Waldre

    I moved my discord bot to GitHub and Heroku today, everything works fine but I get this error that causes the bot to stop working

  • FFMPEG fails to trim beginning of clip

    23 février 2020, par miguelmorin

    I have two .MTS files taken in sequence and I want to trim them to the first five seconds. This command works for the first file :

    ffmpeg -ss 0 -to 5 -i 00117.MTS -vcodec copy -acodec copy start_00117.MTS

    The result is 5 seconds and 17 MB, as opposed to the 12 minutes and 2 GB from the original.

    The same command on the second file fails :

    ffmpeg -ss 0 -to 5 -i 00118.MTS -vcodec copy -acodec copy start_00118.MTS

    The result is 12 minutes and 2 GB, like its original file.

    What is the problem ?

    Full log :

    $ rm start_00117.MTS; ffmpeg -ss 0 -to 5 -i 00117.MTS -vcodec copy -acodec copy start_00117.MTS
