Back of the envelope estimate:

4096 x 2160 x 24 x 60 is your theoretical max in bits/second, 127 billion.

Assume that to counter YouTube's compression we need 16x16 blocks of no more than 256 colors and 15 keyframes/second; that reduces it to

256 * 135 * 8 * 15 = 4.1 million bits/sec.

That's not too awful. Ten minutes of this would get you about 300MB of data, which itself might be compressed.

To do PiP (picture in picture), you would be restricted to a much smaller size, but otherwise good calculations.
