Jitter In CS4 – need help fast
I’ve been working with some DVCProHD footage and have a problem with jitter or slight studder in the video. It’s really evident in a pan of room. Instead of a smooth pan it has a slightly jerky playback. The footage will play fine on someone elses FCP system. Today’s footage comes from a different camera and it still does it.
I really need to get this figured out fast. The producer wants it fixed NOW!
What are the first things to look for? Would a striped drive array work better? Is there a setting I need to check? The footage was shot DVCProHD 720p/30. I made my project with the Premiere preset 720p/60. On past projects it exported with the jitter.
I’m on a MacPro, Premiere CS4, 6Gigs of ram. The footage lives on an internal 7200rpm Seagate Barracuda.
Thanks!

You appear to be out of my league. But, have you checked the obvious, the frame rate of the videocam, and frame rate in your software. This happens on horizontal panning in the latest Canon 5D Mark II video in 1920 x 1080 mode, it is a lens image stabilization problem in this case and not the software, I know you have tried different cameras but, the problem could be in the cameras or lens (according to Canon Australia) they now make IS lens to fix this pixel shift or judder artifact .
Good luck, we do not pan much anymore as it is very noticeable on a large Sony 46″ Bravia Full HD

The jitter is most likely related to an issue with the frame rate.
Was it shot at 30 pN ? Any reason you are using a 60P timeline ?Try setting up a custom preset at 720 30P.

I created another project and chose GENERAL > editing mode:P2 720p 60Hz DVCPROHD > Timebase: 29.97 fps. it still has a slight stutter every so often.
I’m not in contact with the cameraman and not sure if it was shot pN. Is there a way to check on this end?
This happens with footage shot from two different cameras.
When I open this footage in AVID it plays smooth but has a blurry scan-like line drifting down the screen if that helps.
BTW: The folks at the Apple store said DVCProHD is a Final Cut Pro codec and the only way to play it smoothly is through FCP.

Ask the cameraman not to pann ?
see what happens.

Re-Install FCP ?

Asking the cameraman not to pan or buying FCP isn’t an option. I was hoping someone has had this problem and has found a solution.

So it sounds like you are using files that were captured in Final Cut?
With Premiere, you would be much better off with the original P2 folder or tape in order to playback natively in the timeline.
A scan line running down the frame could simply be a preview artifact from the video card. What does the export look like?

This footage was captured on P2 with a Panasonic AJ-HPX2000 camera. I used a Panasonic P2 reader to copy the footage on to my computer’s hard drive. I’ve also had the same problem on a second project with footage shot with a Panasonic HVX200 & Firestore 100 (Quicktime DVCProHD 720p/60).
I should be able to use the footage natively in Premiere CS4.
I took a hard drive with some jumpy footage to someone’s FCP to determine if it was the footage having problems or my computer It played fine on their system so I assume my Premiere / Mac is at fault.
Is there a codec that I need to download? Can someone walk me through setting up the project to see if I missed something obvious?
As far as my AVID, that blurry scan line didn’t show up on my test DVD. My problem there is that the exported quicktime has gray bars on it meaning I don’t have a quicktime codec for HD – or maybe corrupt. I have two NLEs on this computer that handle native DVCPro HD footage. Shouldn’t there be a HD quicktime codec installed?
I really want to get this fixed in CS4.
Thanks for the help!
