I finished shellmind (https://github.com/wintermute-cell/shellmind) a few days ago, and it might interest you! It avoids having to copy-paste commands, by integrating directly into the shell and let's you review the real command before send-off. It's also general purpose and can handle more then just ffmpeg.

Coincidentally I made a shell script (https://github.com/pgodschalk/dotfiles/blob/main/bin/ai) around the same time, though it doesn't put the command in the buffer. I might borrow that idea. One thing I did add though, and would recommend, is an --explain flag. Usually if I don't know e.g. ffmpeg, I tend to want a short overview of what I'm actually about to run.

Seems to be a common thing. I did something similar two days ago. Pretty helpful so far: https://github.com/combatwombat/cmdline-ai-helper
