Playback jitter on photo moves

Hey Walter.....(Or anyone)

I just finished editing an FCP sequence that needs to be shown by another vendor at a meeting in several days. He doesn't use Playback Pro, and I'm not sure what he is using. I will be there, so I offered to bring my MBP, an external drive, multiple flavors of the encoded piece, as well as several DVDs of the program.

When I play the H.264 from a portable iomega 500GB drive, some of my pans and moves on still pics look a little jerky. They looked smooth in FCP. What would you suggest to give me the best playback performance?
It's the kind of thing that most of the audience, and my client, will never notice, but it is bugging me big time.

I also have a Lacie D2 Quadra that I could take, if that would be much better than playing from the Iomega drive.

Suggestions?

Thanks,
James

James, sorry I missed this while I was out of town.

It may be too late now, but I'd advise finding out for sure how the other vendor will be playing this and delivering accordingly.

The stuttering in your H.264 file is probably caused by high decode complexity (CPU) rather than high data rate (disks). For Quicktime playback, I prefer ProRes 422, which plays well in HD on just about any recent computer.

No worries, Walter...thanks for your reply. We used the DVD playback, and unfortunately the AV contractor had a bad VGA connection going to his main ceiling mounted projector. He ended up running it via an SVideo cable. Oh well.

Yikes! But it could have been worse -- he could have run it composite...
