What are some good / mature / performant libraries to programmatically achieve compositions of text, audio and image files, perhaps with a timeline in which these can be declared at various timestamps, and the output is a video file?

Does this one do it?

Essentially this repo is a robust wrapper for FFMPEG, which is what most programmatic video editing tools use in one way or another.

I've had a lot of fun with https://github.com/mifi/editly. It seems a bit RAM hungry as you define lots (dozens?) of clips thought.

I found it super useful to write a quick Python script to auto-generate JSON in the format it wants, combining screenshots, headers, footers, and such into a nice demo-video.

Just curious, what is your use case? I had to do some stuff like this for a school project a while ago, wrangled with ffmpeg whilst cursing under my breathe. Curious what other people do this for

Essentially the same thing - ffmpeg syntax is very complex to maintain so I wanted to find out if there are better approaches to implementing this kind of solution.

The use-case is mostly audio conversations converted to video with the relevant speaker's face shown prominently, based on timestamp data.

AviSynth+ [0] is one of the most mature libraries around. It's performant enough to run live (usually), though I don't imagine it's heavily optimised.

Maybe Narakeet?

gstreamer is mature... still hard to say if it matches the other requirements (it is notoriously difficult to figure out and use from its docs)
