HDV work flow questions
If I may, two questions: 1-If you decide to use footage from the HVR-Z1U as down-converted DV, is the quality worse, comparable or better than other 3-chip camcorders (using 1/3 inch chips) that shoot native DV (as opposed to HDV) such as the AG-DVX100A or XL2? 2-Does a work flow of up-converting from HDV to HD in FCP using a third party card require super fast drives with enormous storage? In other words, are we talking about uncompressed HD as the only high quality option for combining HDV and HDCam material? Best to all, -Jason

I’ve not done a side by side between a 3k DV camera and that HDV camera so can’t comment on the difference, but would *guess it’s better on the HDV camera.
Yes, if you upconvert HDV to uncompressed HD, you’ll need the fast drives to handle the media files… Huge systems is selling a superfast set of 4 gig fibre channel arrays… Medea probably is as well, and of course you could use Apple’s arrays as well.

Thanks Jerry. I wonder how fast the drives need to be. I have a single channel raid 0 drive by Huge which is fast enough to do uncompressed SD, but do I need a dual channel or fiber channel drive for HD? Also, is there a measurement to tell me how many gigs of storage is required for each hour of uncompressed HD? -Jason

IO do a nice little freebie sw calculator available on their website for doing these sums.

We just did a little test with the Z-Cam on my FCP system.
We were able to import over firewire from the camera both in the HDV and in the Apple Intermediate Codecs (1080i60). No difference that I could see between those on the test.I pulled the clips into a normal DV NTSC Timeline an rendered it. I tried letterbox, a full top to bottom Pan-&-Scan size and also blowing up the clip to 100% and pisitioning it so that only a part was visible in the DV Canvas. It look great in every version.
Now our main purpose for using the camera is to shoot stuff that will be composited in Promos and Spots, so We had to get the clip into After Effects. The HDV and Apple Intermediate did not work in After Effects. So I up-rezzed it to Uncompressed 1080i and that woked in AE and still looked fine. The Up-rezzed clips even played on the desktop monitor using my SATA-Max Raid from Promax. Of course I only have the 20″ displays, so I had to cut the view size to half.
During all this several people told me verbally that they didn’t like how the Sony took pictures (Artifacts in high-contrast settings and on motion) and that they were waiting for the JVC camera to come out.

HDV footage I’ve shot on my Z1 downconverted in camera for editing as DV looks noticeably better than DV footage I’ve shot on the PD170 or XL1
