Why do things like confetti ruin the birate of videos and livestreams?
In: 12
Videos are often compressed such that only occasionally is an entire frame defined (called a “key” frame) and then subsequent frames only include information about what changed since the previous frame. An example would be if a student was sending a paper to someone for proofreading, it would be much less writing to just say what the editor changed from the original paper instead of sending back the entire paper with the edits.
This works pretty well with most kinds of video because what changes on the screen between frames is relatively minor. But things like confetti are very difficult to compress because there is a lot changing all across the frame, and those changes are significant differences. The bandwidth necessary to define those changes dramatically increases and because so much changes in a relatively short period of time the “only tell me what changed” method doesn’t work very well.
