These guys are trying 4K capture.

FYI...I've currently run into an issue using After Effects at the office. Aparently I'm the first person to call and complain about this. I can't render out files larger than 4096x4096 in any file format higher than 8-bit. I need to render some 6K and 8K cineon files. After three days on the phone with Adobe, their answer to me was "render out a a lower resolution or buy a Mac.". Nice. We'll be contacting the project manager tomorrow. Grrrrr...

I guess my point there was that we're scanning and manipulating data at 8K. Hehehehehe...
