But you *should* use blur! Don’t use a gaussian blur, though. Use Motion Blur in Photoshop, or its equivalent in AE (Directional Blur?) and set it at 90 degrees, vertical only, 1 to 2 pixels. It’s the only way to do it.

Michael,
You’re still recommending SDI after the posts to you about it in the AJA IO forum? 🙂Tim,
Check out the Adam Wilt and Graeme Nattress links about DV and SDI here:

Ed[Michael De Lazzer] “I’d suggest an SDI option for post. Don’t just record off of firewire, put it in a real bay when you’re ready to conform and capture uncompressed off of SDI. Then you’ll avoid the DV artifacts that come with the compression”

If file size is not an issue, but compatibility with old PCs and Macs is, then MPEG1 is the most universal choice. Highly compressed, it doesn’t compare well to WMV or QT, but it still looks pretty good when it’s not squeezed too much. Otherwise you’ll have to consider a codec that won’t play on some machines without the viewer installing the codec. You could also compress to 2 formats, say Windows Media 9 (which has amazing quality) for PCs (95%+ of the world) and Quicktime/Sorenson3 for Macs. Let the viewer decide which to use.

Maybe too late for this thread, but….. my soundperson is also a shooter for our state’s PBS affiliate and uses the Glidecam with their PD-150. She’s used it while skiing backwards and while strapped in the back of a jeep to shoot a bicycle race. It looks great.

Are you kidding? I hear you can make a killing!

Are you creating an MPEG2 before burning? And at what bit rate?

The MDDs have 3 busses, one is 100, one is 66, and the optical buss is 33. Some folks have hooked up 4 drives and striped them across the faster busses, then installed a boot drive to the slow optical buss. The better solution is to hook up 2 drives to the internal ATA 100, and 2 drives to a PCI ATA100 card, leaving the ATA 66 buss for the boot drive. The ATA 33 buss is just too slow.
Ed[Stephen de Vere] “Both ATA busses in MDD Macs support drives over 137GB.
I read a post, in “Mac OSX” I think, about a 5 internal drives setup in a dual G4 MDD – the fifth (system drive) under the Superdrive, connected to a Sonnet 100ATA PCI card.” -
Actually I don’t own any Decklink products, I use AJA products, I just have very little need for capturing at 10bit, and we are a production house *and* a post house, where we sometimes do *serious* work. 🙂
As for DV, I don’t shoot it (except one cooking show in Italy a few years ago with a “just fine” DSR-500 and 2 weeks of World Cup Beach Soccer in Brasil this month with a “not as fine” DVX-100A), but DV with a 2/3″ chip camera vs DV with a 1/3″ chip camera is a world of difference.
Ed[uncompressed] “great man, enjoy your decklink product. 8 bit does band. if the guys you have shooting are not pushing it, you will not see it. if your footage is pushing it, you certainly will. if you do post production work and try to pull keys or do serious work, it is incomparable. ask your post house if they want to work with 8 or 10 bit when pulling a key. there is 2x more info to work with. i can show when this occurs in dvcpro HD (8bit) and when it goes away when you capture uncompressed. again, if you shoot regular footage and don’t work in post or notice the difference. lots of people think DV is “just fine”.”

SATA drives are the same size as ATA drives, so you can mount them in the same cages in the G4 as ATA drives. Instead of hooking up the computer’s ATA cables to them, buy a Tempo or SeriTek PCI SATA card and run the cables from the card to your drives. For more versatility get the SeriTek external SATA card and put your drives in an external enclosure.

Decklink *doesn’t* say, of course, that analog Beta SP is 8bit, because Beta is ANALOG. What they *do* say is that their 9bits is more than enough to handle Beta.
Ed (still without any 8bit banding)[uncompressed] “if decklink says analog beta SP is 8 bit, then decklink is wrong. not sure why they would propogate such information if indeed they are…
HDCAM is 8 bit, but it has over 6x the data that you will find in SD video, so not sure of the point there.
