Here's how the Domesday Duplicator works, since you're thinking in terms of video, which the output of the DdD is very much not:
There is no such thing as a "frame" to the DdD. There is no such thing as a "resolution" to the DdD.
It's a blazing-fast ADC hooked up directly to the RF output of the laser pickup on one end, and to a USB3 link on the other end that streams 10-bit data in 16-bit words (because packing it would create processing overhead) at 40MSPS, which is then packed on the PC side.
2 bytes per sample at a 10/16 packing ratio. 40000000 samples per second. 60 seconds per minute. 30 minutes mentioned by WarrenO.
(2 * 40000000 * (10 / 16) * 60 * 30) works out to exactly 90 000 000 000 bytes.
