Good to get back to this project again. I share here because I like documenting progress somewhere. – added ability to automatically save to mp4. What’s nice about this is it eliminates the duplication of frames, making for a very compact video. I might add code to run pre-existing videos through it and see if it can remove duplicate frames automagically. [I know there’s ways to do that, but I like trying to figure out how things work]. This is from a plugin that allows for simple video export in Processing 3+ and uses ffmpeg. I’m very familiar with ffmpeg and its capabilities so extending it through it should give more possibilities.
