Possibly the dumbest question known to mankind
what a way to come in. Could anyone here explain HDV-SD60P and where/when/how it should be used? Thanks.

There is also DV-24P/24PA that can be captured as 480 lines, progressive but in traditional 4:3 format. |

480p60 is a broadcast standard under ATSC. Some stations use it that have upgraded to digital broadcasting, but aren't going HD yet. 480p60 also offers easy upconversion to 720p60, though for that you may want to wait for the HD200/250 so you can shoot it natively.

o.k. Thanks- could one assume that shooting HDV480/ 60p would give more "colorspace" than shooting in SD (perhaps a second question),even though they are both 480 lines?
Would this be the format to use to shoot footage for slo-mo?(no more questions) |

Yup, this is what you'd use for slow-mo. It works pretty well too. Here's one thread on it: http://www.dvinfo.net/conf/showthread.php?t=67251 It should answer your next question of how to do the slow motion. As far as color-space it is HDV and thus 4:2:0 instead of 4:1:1. Not more, just different. Brian, it's not technically "HD" (though that is a relative term in itself), but it is recorded in the HDV codec in order to fit all the information in. They would have made it possible for you to record 720p60 if they had a more efficient compressor (which they do now for the 200/250). But even though it doesn't have the resolution of HD (720 or 1080 lines) it can be scaled up quite nicely. |

It is actually classified as ED (extended definition) under the ATSC standard - credit to Barry Green for this bit of information.

No different of what happens with bitmap encoding, JPEG doesn't dictate which resolution you must use. As long as the final result can be stored in a DV cassette, pretty much any resolution is OK. There is also 576p available :) |

Temporal = time, spatial = space. It basically means that when you go with progressive instead of interlaced scanning, you end up with more samples in both time and space, so you have finer motion and detail. Plus you get rid of all the problems with interlacing that have been plaguing us for the better part of a century.
