I have spent the past few years searching on and off, and was unable to find the PS3 tech demo in better than 480p 4:3 with letterboxing. Certainly nothing HD. The best I found was a 60fps version buried in an obscure corner of the internet. I can believe that it was produced in HD, but I'm certain it was never actually released in HD.
I think it was first shown at e3 2005 during the Sony presentation where the PS3s hardware specs were finalized. I can't find anything better either. Really anything on youtube isn't in its original encoding to begin with.
Maybe just concept art:

So at best you have 100 minutes of official HD video (
[email protected] H264/AVC x264 [10872 kbit/s] was the best encoding I can find), some concept art, and various cutscenes at DVD quality or less from every other source: Original FMVs (320×224@15Hz), Toshiba DVD (640×448@15Hz & 717×456@15Hz), Crisis Core FMVs (480×
[email protected]); FFVII Technical Demo (640x480@60Hz)
That's 143,856 HD frames, 23,877 DVD frames that need to be color corrected, 6,180 DVD frames from the Technical Demo, and I'm too lazy to figure out the math on the FMVs which are all antsized.
