I'm really confused about the recording format. Is it HDV or some form of AVCHD? If AVCHD, is at the max rate? What did Sony mean by "the highest

Fast computer, yes...but that is just a standard computer today...nothing special. RAID array, no. Cineform or equivalent compresses to levels managable by one disk.

JVC says: So, even at 24 frames a second for both, 1440x1080 would have 69% more pixels than 1280x720. Using 25Mb/sec and 19.7Mb/sec respectively, that is 33% more compression. If using 30frames/sec...

Both A1 frame mode and V1 progressive mode are written to an interlaced 1080i HDV file. In both cases the entire 1440x1080 image is a single instant.

How does the recording differ?
