1GB per hour of high-def video? Which encoder are you using, that sounds really good. ...Actually, now that I am looking up some actual data it does look like many formats come in lower than I expected for an hour, though I don't know whether those formats are: A) Free to use, and B) Full HD (1920x1080, what we in the EU call HD) video losslessly compressed. My back-of-napkin mistake was looking at a random 1080 video, seeing it was 2.2GB for 24 minutes and extrapolating from there. Let's see, Apple Animation (which I don't know whether it's free, but it can compress losslessly) comes in at 597.2 GB/h of 1080p video. I can't find numbers for VP9, but it is patent-encumbered. I can't find numbers for Lagarith, but it is GPL, although as a fork of HuffYUV it's optimized for encoding speed rather than storage. Well, according to Wikipedia, lossless compression can achieve up to 12x compression, so let's call it 80GB/h (I'm back-of-napkining again, bad habit I know), so 640TB/y?
