You're being modest in describing it as an FFmpeg "wrapper". Although technically true, I can see a lot of thought and effort went into the UX, and I think that's where the value lies. Good job!
Do you work for microsoft?
Very true, but just want to note that ChatGPT is also great at creating CLI input for ffmpeg, yt-dlp, etc. And of course, Handbrake remains the O.G. for open source, cross-platform video encoding.
Do you work at Oracle?
Do you work for local government?
If you're not trying to pick a fight, the more sensical reading of this is "where the value [of this tool] lies".
I tend to include the codec developers in the "ffmpeg developers" for simplicity as there are many that work in both areas.
The complexity in using those codecs isn't the ffmpeg command line, it's knowing which options to use.
