CS4 Premiere Pro jerkey playback..

Hello,

Ok I will start by telling you what computer I own:

Mac Pro
TWO 3.0 DUO intel chips
4 GB of ram
3 internal drives equaling about 2 TB of storage with plenty of room left
ATI Radeon X1900

Ok now the question, I just purchased the adobe premier production suite. When I pull some HDV clips into Premiere Pro and play them on the time line they are really jerky like they are skipping in slow motion. Then other times it plays back smooth. Now this only happens when you are watching the clip after you put it in the time line and play it from there. If you double click it in the asset window and open in it in the editing/preview window it plays back smooth.. Why is this? Has anyone had this problem?

I called adobe, they told me to update my ATI radeon x1900. I did and I still have the same problem...

Thanks
 
If the thin line above your timeline is grey, your media matches your project settings and wont require rendering to preview.
If the thin line is red then it needs to be rendered to preview. Hit enter and let it render a preview.
If the thin line is green you have already rendered it and it should preview in real time. Unless you have a really slow computer.

What about if its yellow?

That means that the footage might need render for playing back properly in real time. It does also mean that your Sequence Settings do not match your footage and thats probably why you are getting jerky playback.

What camera are you using? It seems that you are using a HDV camera that shoots progressive footage while you are trying to edit it on a interlaced Timeline, thus the mis-match.

Well, I am using a canon A1 capturing onto a firestore as quicktime. I am pretty sure its 1080i because I have been editing in FCP for years with this camera and the firestore and I have always set that sequence to 1080 60i... Premier pro only has one that says 1080 30 (60i). Thats the one I need to pick correct(under the HDV folder)?

Yes, you are using the correct Preset.

However, Premiere Pro HDV is mpeg and not quicktime. You should be able to change the settings in the Firestore so it records mpeg. Try it and see how it goes. :)

I actually tried the CS4 trial and had the same issues on my windows laptop. That was with using M2t files. It didn't seem to matter if the timeline was rendered or not. Cs2 on the same machine runs fine.

The trial versions don't support HDV editing, so if you're having trouble with HDV files, that may be why.
 
ok, what the heck. I just tried working with AVCHD footage on premiere pro and I have the same problem with the choppy footage.... Does anyone have CS4 and working with AVCHD and getting smooth playback.

Its not my system, I now have upgraded and have 12GB of ram TWO 3.2 quad core and a NVIDIA GeForce 8800 GT 512M graphic card.... its must be adobe.... ???
 
I am having the same issue.

my specs for reference:

Q9650 stock
8Gb
4870 graphics
Ultra 320 SCSI drive

when I view it in the source window, sometimes it sutters sometimes but rarely it doesn't. That was on high quality. i broke it down to draft quality and it plays better but of course looks like ****. I am lost and don't know what to do. I was doing a forum search when i came across this thread. The thread I am looking for was something like Premiere Pro CS4.1 wins AVCHD editing er something like that. What I vaguely remember was that someone with a low end computer was running PP4.1 no problems... and i think a responder later said the guy had a workstation graphics card.... still searching for that thread..

Check out this video folks. You can start to watch at 5:18 for the AVCHD (MTS) playback in real time. I can edit native AVCHD at full resolution in an AVCHD timeline project, HDV or even a P2 project.

2.66 GHZ Quad Core 8400 (Yorkfield)
Nvidia 9400 GT
4 GB Kingston RAM
500 GB Recertifeid Western Digital Hard Drive.

The system above was less than $600.00 to build. It kicks ass though.

I found the playback in the source file to stutter and play like a rubber-band. That was my Q9650 at stock 3Ghz. I recently did some overclocking. I raised the fsb to 400 thereby making my final OC @ 3.6Ghz by keeping the 9 multi. After I complete a full Prime95 blend test I will retry the playback with the lowest multi using the 400fsb still. I've already completed and passed a 25 iteration LinX test using 6144mb. So this will either confirm or debunk the 'video editing requires high fsb' theory.

Will report back later.
 
I did my testing running the 400fsb x 9 and playback in PP CS4 went smooth. I changed the multi to a 6 x 400fsb and the playback went back to being choppy and rubberband like. So the stats were 2.4Ghz @ 400fsb and it was not playable in the source monitor. My experience is it played worse than running @ 333 x 9 = 3Ghz
