David -

Will Aspect HD be able to accept / edit footage made from these cams?

HDV - yes

AVCHD - wait for his answer.

CineForm products will the way to go for the Sony V1U, as we only solution we detects and removes the 24p in 60i pulldown that Sony applies during capture. The 24p on that camera is stunning, no temporal judder like the Z1U, so this will be a very popular shooting mode -- you are going to want/need Aspect or Prospect HD.

If the latest release we have added support for converting through HDLink any third codec that pays in DirectShow (i.e. if MediaPlayer can play it we are likely to be able to convert it.) We haven't done any AVCHD testing yet (Sony, we need a camera.)

When you say "Judder", are you referring to the motion artifacting?

There has been previous posts in other threads/forums that suggest that there is motion artifacting / judder when panning with HDV cams because it uses MPEG-2. Is this true?

No, that is not true; MPEG2 happily encodes 24p, otherwise HD broadcast woudn't exist, nor would 99% of DVDs. The judder I was referring to was due to the Z1s 60 Hz sampling rate to generate 24p. The V1U has the correct sampling at 24/48Hz to achieve smooth 24p motion (as smooth as 24p can be, that is.)

What about when recording at 60i?

Does any of the "juddering / motion artifacting" happen when panning at 60i?

The smoothest movement (of camera or subject or a combination of both) is when you film at 60i Andrew. In this mode you're effectively shooting 60 different images every second, albeit half vertical resolution images, but it sure gives the smoothest motion (and the worst comb effect).
