[Brian Wells] "... Do I misunderstand the analog output of a HDV camera? Just looking at it, it doesn't appear any more "uncompressed" than if one were using DV, but then I haven't verified this either. ..."

Hi Brian: It depends on the design of the camcorder.

For example, Sony's techs in NJ tell me the Sony DSR-390 and DSR-570WS DVCAM camcorders output "live" (not from tape) analog component video which does not have DV compression applied to it. This "uncompressed" analog component video is 10-bit 4:2:2. It's not 36-bit 4:4:4, but it's much better than DV-compressed 8-bit 4:1:1 (NTSC) video. (I didn't ask about the s-video outputs of these cams, regrets.)

I suspect other camcorders route video signals in various ways. I suppose the senior techs at each manufacturer's "home" office aren't necessarily infallible sources of this information, but it would seem a good place to start.

All the best,

- Peter
