Note: This site is currently "Under construction". I'm migrating to a new version of my site building software. Lots of things are in a state of disrepair as a result (for example, footnote links aren't working). It's all part of the process of building in public. Most things should still be readable though.

Get Crop Of Black Bars In One Line

This crops off black bars automatically.

TODO: write up notes on how it works and put in example without the gif stuff

TODO: Put in `-ss 30` or the like at the start since opening splash screens may not have the bars

Code

ffmpeg -i "input.mp4" -t 1 -vf cropdetect -f null - 2>&1 | awk '/crop/ { print $NF }' | tail -1 | xargs -I{} ffmpeg -ss 25 -t 9.2 -i "input.mp4" -vf "{},fps=11,scale=380:-2:flags=lanczos,split[s0][s1];[s0]palettegen=max_colors=52[p];[s1][p]paletteuse" -y "output.gif"
