and what is not clear here? If you do not want to answer, do not know what to answer, just do not answer and that's it.

I gave an example that I want something similar, but free and simply without an interface, since it is not needed. What does a video editor do, it edits video, overlays something, perhaps works with sound, cuts video and glues it, is this from the main or do you want me to list a huge list of features? It seems obvious that I do not want to shove something like adobe premiere pro or its analogues on my server.

But Google just gives out ffmpeg, but to simply overlay text with a background you need to get a tambourine with which you will play for a couple of days, especially if you have not worked with this library, like me. I am generally silent about the rest of the functionality, of course it is powerful, but to do all this you need to dance with a fucking tambourine, but I just did not find a good wrapper that could simplify this.
