^Exactly!
The problem, unfortunately, is still one of size.
Let's assume YUY2 (2 bytes/pixel) to make the calculations easier...
[1920*1080 pixels/frame] * [2 bytes/pixel] * [24 frames/second] * [7200 seconds] = 716636160000 bytes, which is ~667GB for an uncompressed two-hour movie.
Even if we can get a lossless compression algorithm that reduces the size by a factor of three, then we still need a medium on which to store ~222GB movies!

... and that's just for the video.
