I'd like to take a video of an egg hatching, but the space on the camera fills up before the action happens.
Luckily, an egg before hatching is boooooring: 99% of the video is a still egg, sitting perfectly still, in stillness.
Which gives me hope that if I used the right video codec, it could do some insane compression, skip the noise artifacts, and manage to get the whole thing on disk. I'd come in later and manually edit out the hours of stillness.
Is there a codec that would do this?
