30p is not good enough. If you shoot with an interlaced camcorder (30i) the end result for a prog-scan TV should be 60p. See this channel for inspiration:

M/MII vs Beta/BetaSP is clearly a fail from Panasonic. With M, Panasonic chose color format that was compatible with NTSC but not with Rec. 601 unlike Sony. With MII, Panasonic switched to U-loading as Sony Umatic, while Sony switched to M-loading with BetaSP/8-mm/DV as JVC/Panasonic had all along, and made the mechanism even smaller. Sony clearly won here. I wonder why JVC did not join Sony - was it the prior allegiance to Panasonic that prevented it from doing it?
SVHS as well as Hi8 were better than BetaSP luma-wise, but worse in every other aspect. Sony advertised Umatic SP as the affordable editing platform for SVHS/Hi8, saying that Hi8 is "negative", while Umatic SP is the editing platform.
