Feature description

It would be nice if the recording of a video could be sped up, so that later playing videos could be slowed down.

e.g if a video is recorded at twice the speed, then playing it normally would appear as twice slower.

Why do you want this feature?

Playing a video slower is super useful, whether to cheat at video games or to play a fast action in slow motion.
