the pro-way of animating in any renderer is to generate separate images, and assemble them into a movie-stream by a video-editor. I do so for say 20 years, Pixar does so the same, so it should work for you as well.

then you can easily try various codecs and codec-settings, without having to re-render over and over again. And it''s crash-proof as well, etcetera.

have fun.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
