  • ffmpeg speed up video - Windows

    11 avril 2016, par Flash Thunder

    In manual it says :

    ffmpeg -i input.mkv -filter:v 'setpts=0.5*PTS' output.mkv

    But when I run :

    ffmpeg -i input.mp4 -filter:v 'setpts=0.5*PTS' speedup.mp4

    I get an error :

    [AVFilterGraph @ 0000000002500600] No such filter: 'setpts=0.5*PTS'
    
Error opening filters!

    Not sure if it means that filter can’t be opened at all or simply this filter is not available.

    How do I run it correctly ? Or maybe my release does not support it, then where can I get the release that would work right ? Win32/x64 binary
