Storage space requirements are insane once you’re not talking about end product. In this case, you need the full recording for every angle, and if you’re actively editing you probably want a buffer as well.

Another example with the same principle: Geophysical survey data. The end product is usually a bunch of SEG-Y files with associated JPEGs, totallengde a few gigs. But the raw survey data is more close to a petabyte: It’s s8mewhat reasonable to think of it as an audio recording consisting of four mono channels * 1000 recording stations * a month duration.

Raw data adds up fast.
