This is just a very simple example.

Note that it only partially "reconstructs". Sound isn't taken into
consideration, and you're losing all information about frame timing,
which is relevant amongst others for fps, variable frame rates, and
audio sync.

You also need to tune your video codec and its quality. And possibly
the fps...
