TV TechTV Technology Focus on Editing: Jay Ankeney HDV was one of the hits of NAB2005. Now, as the dust is starting to settle, trying to survey the spectrum of how major editing manufacturers are tackling the challenge of posting that long-GOP (group of pictures) format is almost as daunting as squeezing a massive high-definition recording onto a tiny DV tape. So, for efficiency, this column has asked representatives of the various players to describe the specific approaches their systems are taking toward editing HDV and what they consider to be its advantages. First off, HDV is actually an MPEG-2 recording format that currently comes in two flavors--progressive (HDV 1) or interlaced (HDV 2). Recording 720p onto tape, JVC was the first to ship a pro-level HDV camcorder in 2003, the JY-HD10U, and this year topped it with the more advanced 3-CCD GY-HD100U with interchangeable lenses. "We don't say progressive is necessarily better than interlaced," said Dave Walton, communications marketing manager at JVC. "But we feel scanning the CCDs progressively does give you a more cinematic look. You can also get better freeze frames without motion displacement, and it is more compatible with most progressive HD display devices. Our cameras are targeted at the emerging digital cinematography market but, of course, progressive recordings can easily be converted to interlaced." Sony, on the other hand, has opted for 1080i recordings in its camcorders, which has come to be dubbed "HDV 2" and was originally introduced in its consumer camcorders. read more...
