You're getting a lot of flak due to how you started off your comment, but I mostly agree with you.

In my opinion there are two kinds of users: 1. Users who use FFmpeg regularly enough to know/understand the parameters. 2. Users who only use FFmpeg once in a while to do something specific.

This wrapper is superfluous for users in group number 1. But group number 2 does not really get much out of it either, for the reasons you've mentioned.

As a member of group 2, I usually want to do something very specific (e.g. remove an audio track, convert only the video, remux to a different container, etc.). A simple English wrapper does not help me here because it is not powerful enough; the defaults are usually not what I want. What I need is a tool that will take a more detailed English statement of what I want to achieve and spit out the FFmpeg command with explanations for what each parameter does and how it achieves my goal. We have this today: AI; and it mostly works (once you've gone through several iterations of it hallucinating options that do not exist...).

Thank you, this explains my thoughts really well.
