Good day people,
I was wondering how to encode a video from a speed of 1 x to a one of 5 x, using ffmpeg.
Thanks in advance for any suggestion.

Speeding up/slowing down video
You can change the speed of your video using the
setpts video filter. The "old way" of creating timelapse or still frame was to first split up a video into individual frames, (for instance, as jpg's) then delete some and recombine the frames. Using the
setpts filter is the new way and is faster and possibly less lossy.
To speed up your video from 1x to 5x, you can type:
ffmpeg -i input.mkv -vf "setpts=0.2*PTS" -an output.mkv
