Remotion
Programmatically make videos with React
Remotion, at it’s core, is a video editor for programmers. You punch code into your computer and the computer spits out a video. Not being someone who uses React (the only JS here is used for Font Awesome), I haven’t actually played around with Remotion too much, but the concept is really cool.
For example, you can have the user type in their GitHub username, render it on the server, and send back a video with their avatar and follower count. This is actually the demo on their site (scroll down a bit).
If you’re looking to get started with Remotion, I’d suggest you look at Fireship’s tutorial, which is recommended by the devs themselves.
