post_processing

Passes that run over rendered frames before they reach the video file.

A post-process is a callable process(frames, memory=arena) that takes the frame batch as a torch tensor on the render device and returns it modified. save_video() accepts any number of them through its post_processes argument and runs them in order.

The built-in passes are bloom/glow (bloom), anti-aliasing (anti_aliasing) and tonemapping.
