That was the logic behind the choice of MPEG2 8mb/s @MPML: you're full (SD) resolution, full color, so you're better than the source (for instance, U-Matic is ~200 lines of ~250 points and a 4:2:0 color space). However, the switch to HD broke all expectations, because the low resolution of U-Matic captured in full SD and upscaled to HD is awful. Somehow that doesn't work out; you must capture even the very low resolution supports with a resolution as close as possible to the target work format (a so-called pivot format). Maybe upscaling the current HD JPEG2000 archives to 4K will fare better, and maybe they'll need to digitize everything from analogue once again...

Scanning in 4k HD in 1998 would not only have produced files too large to be processed and stored practically by computers of that time, but there was no scanning equipment capable of that. Also gives them a nice justification for their budget year after year.

- wazoox 9y agoIn 2003 I did a consulting gig for the _Forum des Images de Paris_ who planned to convert their movie archives to digital. Back in early 2003, scanning the existing video and film stock in HD of any kind (720i/p or 1080i/p) was incredibly expensive and not generally available (most post houses simply hadn't any HD scanners or video capture cards yet, except for high-end film work); I unfortunately had to advise them to stick to SD...
