caching

Do you cache frames? anime usually display the same frame extremely often.

They're not exactly the same. It's not necessary to do this.

This is not true. the speed improvement from adding this would be significant. Especially if you diff sequential images. Often animes only have sound, with few objects moving around. This lasts for a few seconds.
