    22 As an alternative when a video needs to speed up to a certain frame rate, `-vsync drop` can be used. For example when the desired frame rate is 59.94 fps:
    23 {{{
    24 ffmpeg -i input.mkv -c:v copy -vsync drop -r 59.94 output.mkv
    25 }}}
    26 With this command a 23.976fps video will be sped up 2.5 times and a 29.97fps video will be sped up 2 times.
