Nanim is an easy-to-use framework to create smooth GPU-accelerated animations that can be previewed live inside a glfw window and, when ready, rendered to videos at an arbitrary resolution and framerate.
When --render-ing a scene, I get the following output on my mac:

All the individual parts files can be played in VLC without problem, but some of the parts are not added to the final.ml4 render. Also, when executing the command manually, no errors and the final.mp4 render works as expected.
