Definitely a lot of bandwidth required. 60 fps 4k would be 1.7 GiB/sec, 120 fps twice that. 3840×2160×10×3×60÷8÷1024÷1024÷1024

- sho 9y agoRAW format doesn't just mean an uncompressed image like a PNG. It's a direct readout from the sensor with minimal processing. It can be substantially larger than you'd expect just based on the resolution * bits per pixel.
- kurthr 9y agoYou are correct, but don't forget the Bayer encoding that makes things smaller!
- sho 9y agoGood point! But in the other direction, don't forget that even those there's less "pixels" than expected from the sensor, there will be more than 10 bits per channel, typically 12 or 14. I shouldn't have said it's larger, not necessarily - but it's definitely not 1:1!
- ShinyCyril 9y agoYou don't need a x3 there since most cameras use a single monochrome sensor with a colour filter array on top – the debayering process can happen offline.
