FFMPEG Snippet Collection
FFMPEG is an extremely powerful tool for converting and editing video material. Not only is it ideal for converting to a wide variety of formats, it can also merge image data into video, crop, add filters and even export gif files.
For my own work I can’t imagine my work without this tool. However, the obstacles for getting started are relatively high, because the installation is more or less difficult depending on the operating system. Furthermore, you work with FFMPEG in the command line, which is a daunting task for some people.
I find the technology so helpful because I have to formulate every action with code so that I can reuse it at any time. That saves a lot of work at some point.
In this article I collect FFMPEG snippets that I find especially useful for my work as a designer and creative coder.
Convert one video-format to another
ffmpeg -i in.mov out.mp4Add audio to an existing video: Stream copy
ffmpeg -i video.avi -i audio.mp3 -codec copy -shortest output.aviAdd audio to an existing video: re-encode
ffmpeg -i video.avi -i audio.mp3 -c:v libx264 -c:a libvorbis -shortest output.mp4
Compress Audio
ffmpeg -i input.mp4 -filter_complex "compand=attacks=0:points=-80/-900|-45/-15|-27/-9|-5/-5|20/20" output.mp4Create images from video
ffmpeg -i input.mp4 -vf fps=1/1 ./thumbs/video%03d.jpgConcatenate Videos
ffmpeg -i ./input1.mp4 \
-i ./input2.mp4 \
-filter_complex "[0:v] [0:a] [1:v] [1:a] concat=n=2:v=1:a=1 [v] [a]" \
-map "[v]" -map "[a]" ./output.mp4
Add padding / white letterbox
ffmpeg -i input.mp4 -vf "pad=width=900:height=900:x=157:y=45:color=white" output.mp4Convert video to gif
ffmpeg -i input.mp4 -f gif output.gif
ffmpeg -i input.mp4 -filter_complex "[0:v] palettegen" palette.png
ffmpeg -i input.mp4 -i palette.png -filter_complex "[0:v][1:v] paletteuse" output.gif
ffmpeg -i input.mp4 -filter_complex "[0:v] fps=15,scale=500:-1,split [a][b];[a] palettegen [p];[b][p] paletteuse" output.gif
