What software is used to process video on the server side?

Question

Video processing

What platform is used for video processing in services like WeVideo, Wideo, PowToon and the like? What software allows you to assign tasks to the server for processing video generated in the web interface? What do such projects use?

Answer 1

I made a couple of services based on FFmpeg : gluing, simple editing. Web UI, task queue, workers.
FFmpeg is great for such tasks. But with him it becomes sad when more complex compositing is required, movement along a curve with variable dynamics. FFmpeg is far, very far from AfterEffects. A couple of times I solved the task of overlaying a dynamically generated inscription on top of a short animation simply by choosing the position for each frame.
By the way, the second option for animations is to raise AfterEffects on the server. It seems that there you can render compositions with dynamic substitution of pictures, texts involved in animation. See for example inlife/nexrender
