> is crazy even compared to other high end cinema camera Is it really? I haven't touched "high end cinema cameras" but if my consumer camera can generate ~1TB/hour and it's a "normal" consumer camera, I'd easily expect 4x that in high end cinema gear for 3D video (multiple videos stitched into one essentially) But again, haven't used any of those or looked it up, so what do I know. It doesn't sound outlandish to me though.

> if my consumer camera can generate ~1TB/hour and it's a "normal" consumer camera If your consumer camera generates 1TB/hour then you're generating data as fast as a Red Komodo [1] recording at 6K "VFX, Extreme Detail Scenes" Consumer quality? A high-end iphone can record 4K 60FPS video and an hour's footage takes up 24 gigabytes. And you're watching 4K 60fps video on Netflix? Youtube? Maybe 12 gigabytes an hour.

  Fair, maybe "prosumer" is more fitting, was thinking of the Pocket Cinema 6K (also from Blackmagic). Not exactly "high end cinema camera" so I still think the data rate doesn't sound out of the world.

  Raw 8K video at 60 fps out of something like a Nikon Z8 is around 1.5 TB/hour, 400-500 MB/s. Of course most people wouldn't shoot at 60 fps for historical reasons, and raw video codecs are intra-only so data rate scales linearly with fps. They're just relatively heavily lossily compressed raw images in a box, basically.

According to https://support.apple.com/en-us/109041 https://support.apple.com/en-us/109041 4k60 recording in ProRes needs 220 MB/s storage, so an hour would be ~792 GB. Sure, you can choose to throw away most of that data with more lossy compression, but the barely-acceptable bitrates used by streaming services are not at all the right point of comparison here.
