Here's why we're excited about Red's announcements of their 3K Scarlet and 5K Epic digital cameras. Their insane resolution. It's one thing to talk about resolution as an abstract number, but Red has a fantastic chart comparing these resolutions to things you're actually familiar with, like your HDTV or your old SDTV. Even the Scarlet, the most affordable of their cameras, dwarfs your 1080p TV in the way that Wilt Chamberlain's "scoring" record dwarfs ours. [Red]
I wanna see data rates!!! based on some back of the napkin calcs... 5K = 5000x2128 (cinema wide 2.35:1) Thats ~10.6 MP. Multiply that by 3 for RGB and you get 31.8 MB per frame. Run that at 24FPS and you get 766MB/s. Even if you go crazy compressing it, I'm not seeing anything less than 100MB/s. That BTW is the convenient theoretical data rate for firewire 800.
All in all a massive, massive system.
