Video stabilization using VidStab and FFMPEG (Mac OS X)

Video stabilization using VidStab and FFMPEG

Examples here use the default settings, see the VidStab readme on GitHub for more advanced instructions.

Here's an example video I made

Install ffmpeg with the vidstab plugin from homebrew

brew install ffmpeg --with-libvidstab

Analyze your video to create a .trf file

This won't modify your video or create a new video, but it should create a new file called transform.trf

ffmpeg -i clip.mov -vf vidstabdetect -f null -

Use the .trf file to create a stabilized video

ffmpeg -i clip.mov -vf vidstabtransform=smoothing=5:input="transforms.trf" clip-stabilized.mov

This should create a new stabilized video called clip-stabilized.mov

Bonus: create a side by side comparison video

Found on a forum here

ffmpeg -i Clip8.mov -i Clip8-vidstab.mov -filter_complex "[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w" merged.mov

@kibotu what is the difference between varenc's version over pnbv's?

well not quite sure exactly, but that one worked for me and the other didn't :/ just wanted to drop this info in case someone else couldn't get the main example to work :3

Looks like varenc/ffmpeg/ffmpeg has been superseded by homebrew-ffmpeg/ffmpeg according to https://github.com/varenc/homebrew-ffmpeg.

What is -f null - do?

This (-f null -) occurs because when performing step 1 (vidstabdetect) we do not (yet) need the final video file, but only "transforms.trf", necessary for step 2 (vidstabtransform).

By the way: "-f" specifies the output format (null in this case) for ffmpeg.

Edits from 2021. There's some errors/inefficiencies above due to changes since it was written (in Dec 2015).

With ffmpeg -i clip.mkv -vf vidstabdetect -f null -I just get the error
No such filter: 'vidstabdetect'
