** Step 1 **
Install ffmpeg with the vidstab plugin.
- OSX: Install via Homebrew -
brew install ffmpeg --with-libvidstab - Linux: download binaries here (vidstab included)
- Windows: download binaries here (vidstab included)
** Step 2 **
Analyze any video and generate a so called transform file, which describes camera movements. The command below generates a transforms.trf file
ffmpeg -i input.mp4 -vf vidstabdetect=shakiness=7 -f null -
Options:
- shakiness: Set the shakiness of input video or quickness of camera. It accepts an integer in the range 1-10, a value of 1 means little shakiness, a value of 10 means strong shakiness. Default value is 5.
** Step 3 **
Stabilize video
ffmpeg -i input.mp4 -vf vidstabtransform=smoothing=30:zoom=5:input="transforms.trf" stabilized.mp4
Options:
- smoothing: Default value is 10. For example, a number of 10 means that 21 frames are used (10 in the past and 10 in the future) to smoothen the motion in the video. A larger value leads to a smoother video, but limits the acceleration of the camera (pan/tilt movements).
- recommended value:
videoFPS / 2
- recommended value:
- zoom: Set percentage (%) to zoom into video. A positive value will result in a zoom-in effect, a negative value in a zoom-out effect. Default value is 0 (no zoom).

Create side-by-side comparsion video:
ffmpeg -i original.mp4 -i stabilized.mp4 -filter_complex "[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w" sidebyside.mp4
