Netflix has about 36,000 hours of content. On Youtube that much content is uploaded every 1 hour and 20 minutes! Or to put it another way, Netflix re-encodes every month what YouTube encodes in just over an hour.

Your numbers are off. Netflix has more than 36.000 hours of content.

Care to cite a source?

Back-of-the-envelope calculation: a slacker suffering from insomnia watching 5 streams of Netflix at once × 20 hours/day × 365 days non-stop would otherwise watch the whole catalog in less than a year.

Convinced?

Not really.

If we unpack your calculation to slightly more typical human behaviour: Watching 1 stream × 10 hours/day × 365 days non-stop, one person would need 10 years to watch the whole catalog.

Doesn't seem unreasonable to me.

You didn't get the core idea of my calculation: to show that Netflix has times of magnitude more than just 36k hours of content.

I don't know the reliability of these sources, but according to one article[1], as of 1 year ago, US Netflix had ~5.8K titles, totaling 36K hours of content. Another more recent source[2] claims that worldwide, Netflix has ~15K titles, so assuming the same distribution of runtimes, it would be closer to 93K hours of content. So, while you're correct, it's still the same order of magnitude.

FWIW, that conversation about Netflix re-encoding their catalog monthly was from about seven years ago! Their process has surely changed since then. :)

Also, IIUC, they re-encoded about once a month, but the re-encoding didn't necessarily take one month of compute time.
