Not the OP, but ffmpeg's documentation is pretty awful to navigate if you aren't an expert in it. It is very technical and exact, but fails to provide examples for most options.

For example, the fpsmax option says you can set the maximum frame rate using "Hz value, fraction or abbreviation." So now the user has to search for how any of these things are to be specified (does a bare 60 mean 60hz? Do you need to include Hz? Is it case sensitive? What are the abbreviations? What is the fraction a fraction of?). And that's a random option I found in the pile of documentation it has.

Maybe it's useful if you use it every day, but I completely understand why people use GUIs whose purpose is to construct the command. Or even LLMs to do the same thing.

I know there are options for everything in FFmpeg, and I’m thankful to the community and maintainers for providing such a powerful and well-documented tool. I sometimes just want a quick video edit that doesn’t involve reading the man pages for minutes or hours.
