While ffmpeg is a powerhouse, I don't use it frequently enough to remember all the options I'd need for my typical usage. Having said that, I have saved some magical incantations over time and built a handy context menu over time https://lmno.lol/alvaro/how-i-batch-apply-and-save-one-liner...

Now I can just highlight a file and:

- covert audio to mp3

- convert gif to video

- convert to mp4

- convert video to gif

- convert video to webp

- convert video to hevc mkv

- convert video to mp3

- convert video to mp3 with artwork

- convert video to thumbnail

- trim video beginning

- trim video end

- drop video audio

- speed up video

- speed up video fragment

- resize video
