Stabilization Settings, Descriptions, and Tendencies

@daniel47, I was curious about the “choppy” filter, how lethargic the video, then if you can apply stabilization… it’s a new MacGyverism that I’ll have to try more, as an alternative to the “ffmpeg > timestamp”!

Speed Up or Slow Down a Video

Use the setpts (set presentation timestamp) video filter (-vf). The argument to the setpts filter is a formula for how to set the timestamp. Some example values:

  • setpts=0.66*PTS - roughly 1.33x speed
  • setpts=0.5*PTS - double the speed
  • setpts=0.25*PTS - quadruple the speed
  • setpts=2.0*PTS - half the speed

For example, to double the speed of a video:

ffmpeg -i path/to/original/file.mp4 -vf "setpts=0.5*PTS" path/to/output/file.mp4
