Bunch of Apple Knowledge Base Articles on video stuff
Apple has updated a number of their Knowledge Base documents on Final Cut Pro and video related stuff. New Goodies:
Final Cut Pro 5: Issues with setting an initial Scratch Disk - nice details, nothing magical going on here.
Final Cut Pro 5: Tips for using devices that handle both HDV and DV
OK, this one's a big enough deal I'm going to summarize:
-don't use "Auto" when capturing, explicitly specify whether DV, HDV, 4:3, 16:9, etc.
-quit FCP before setting up for a new session so you can start "clean", and don't fire up FCP until HDV device is on, tape loaded, and configured
-quit FCP before changing modes (DV/HDV) - apparently, There Are Issues if you don't
-and of course, avoid recording DV and HDV on the same tape, or recording 50i and 60i on the same tape (if using a Z1U, for instance)
More details in the article, but very sound advice!
Final Cut Pro: Assemble Editing with a Panasonic D5
If you're trying to master using Edit to Tape in FCP, there are clearly some "woopsies" involved. If you're not recording at the in point, having your In points occur a few frames early, or getting duped frames at In point, this is something that isn't quite perfectamundo with a Panasonic D5 deck. Read for workarounds and fixes. My takeaway on this is that D5 doesn't quite do right. And since D5 users represent about 0.005% or something like that of FCP users, I wouldn't expect the FCP team to be leaping over themselves to be fixing it pronto the way they would for a DV issue, for instance.
Cinema Tools and Final Cut Pro: Limit file size for reverse telecine - apparently, if doing reverse telecine to remove 3:2 pulldown, files larger than 2.5 GB can create problems. They suggest splitting large files or recapturing to end up with clips smaller than about 2.5 GB. Well, HELL! If it were 2.5 TB I could understand that limitation. But 2.5GB is only about a minute and a half of 10 bit 4:2:2 NTSC video. Harrumph! That blows. (Or should I say blowzors in dork-o-matic leet-speak?)
Shake 4: Using Convert and Adaptive retiming with the existing field workflow
OK, here's one for the Advanced Class - if you know what you're doing in Shake (and that's NO SMALL ASSUMPTION) - here's some tips on retiming clips and dealing with fields, 3:2 pulldown removal, retiming, etc. A lot of boils down to "this stuff be slow, why don't you pre-bake it and save yourself a lot of time?"
Final Cut Pro 5: Issues with setting an initial Scratch Disk - nice details, nothing magical going on here.

Comments:
I think Apple will have to clear up the issue with removing 3:2 pulldown on files larger than 2.5GB. I had a 16mm project telecined to DVCPRO HD - 1080/59.94i and then tried doing a reverse telecine with Cinema Tools and ran into this problem. I only had an hour of footage (a short film) but at almost 1GB/min of footage, a 2.5GB limit turned out to waste hours of my time. The silver lining: I now had bite-sized chunks to backup to DVD-Rs.
Another frustrating problem I came across was that Cinema Tools needs each clip to start on an A-frame. Because I transferred the whole widescreen frame there was no burn-in (it just doesn't fit), so I had to scroll through and find the pattern frame by frame to figure out where to cut so that the next clip would start on an A-frame.
I think Apple will have to fix this problem because the new Panasonic HVX200 will basically achieve DVCPRO HD - 1080/24P the same way, and people won't want to spend hours cutting up their footage just so they can edit in a native 23.98 timeline.
While the DVX can remove the 3:2 pulldown when capturing from tape, you can forget about that with the HVX where you'll just be able to drag and drop the files from the camera or P2 card. I suppose they could implement some other way to quickly and easily remove the 3:2 pulldown outside of Cinema Tools...

I can voice for the "this is slow so preprocess" in retiming w Shake. However, the quality of their retiming... unbelievable. Just makes me wish I had a rack of slave machines... sigh...
