HD footage is jumpy...on a DUAL 64

Hi,

I have an AMD 64 Dual core 3800+, 2gig RAM, 3 250G 7200rpm hard drives, Geforce 6600 LE, and whenever I playback HD footage on the premiere pro 2.0 timeline it is jumpy! I play it with VLC or Media Player Classic and there's no problem. But it gets weirder! Even after I render the footage on premiere, it is still jumpy. And I'm not even using any effects at all. I checked the adobe website and I seem to fullfil all the system requirement for realtime playback (even with magic bullet effects being applied!). It MUST have something to do with my settings. I really don't know what's the deal here. It's a pain in the ass to edit like this. Any advice will be apreciated.

cheers
 
Do you have any cameras or decks connected? Via firewire perhaps? Check your playback settings and make sure it's not trying to play on anything but your desktop.
 
Hum, I have a TV connected via s-video cable that displays what I'm editing and I have a firewire cable that is connected to the pc but is not connected to anything...I leave it connected so I don't have to plug it in on the back of the pc everytime I need to connect my camera to it. I'll try removing both the s-video cable and the firewire to see what happens. But I pretty sure I can select this on the project/playback settings on premiere. I never thought this could influence the playback but I'll give a try. Thanks!
 
I tried it and it didn't work. I don't know what could it be. I pondered that I might have an hard drive issue and that 7200rpm (maybe I need 10000rpm) would not be enough, but if this was the case, then I think the video would play jumpy when I played it outside of the premiere environment too. And this is not the case, since it plays beautifuly on media player classic and any other video player. It is only jumpy when I play it on premiere. This is making me edit in very very hard and upseting way.

Do you think my graphic card settings might influence this issue? Should I get a 10000rpm hard drive?

Depending on how much footage you have to edit, it may be more efficient and cost effective to set up a RAID. But it's weird that your footage plays fine with everything but Premiere. Are you viewing the footage at 100% size? It might help to view it at 50%. Not sure though.
What a frustrating problem.
Are all your drives identical? If two of them are (same manufacturer, model, size, etc), you might be able to easily set them up as a RAID 0 without too much trouble.
What type of footage is it anyway? HDV? Are you using any flavor of Cineform? As I understand it, HDV has a low bitrate so it doesn't require blazing hard drives, but it demands processing power. The Cineform Intermediate codec uses a higher bitrate, so is harsher on hard drives, but less on processor.
Not sure about the graphic card- I do know the Cinform Intermediate doesn't rely on it at all.
(Here's hoping I'm right about most of this stuff, and that it helps!)

Yes, it's very weird to be able to play it smoothly everywhere except on premiere. I'm not using cineform, I'm capturing using premieres' preset for the FX1's CF25 HDV (pal). I'm going to try viewing the footage at 50% just to see how it goes. I'll probably try to set everything up as a RAID too. Thanks for the tips, broham.
 
Tried it all and it still won't work. I'm going to try to increase my pcs' virtual memory. I know it's a long shot but I'm running out of options here.
 
I think I might have found out what the problem is. I visited http://www.johnrofrano.com/hdv.htm and read that only one of the cores is used durring previews (which is weird because when premiere is loading a msg apears saying that a dual core has been detected). So, since I have a AMD 64 Dual core 3800+, only one core might not be enough. I don't know if there is a way to "force" my pc to use both cores durring preview?
 
Still weird that you're having a problem. I was using Cineform, but I was able to preview 720p content (that's full 1280 wide too mind you) on a Pentium 4 2.4, 7200rpm, 1Gb RAM
 
Darn it! I can't belive it. There's not a freaking way to make it work! Each core has 2.01 GHZ. Do you guys think if I increased it to at 3 GHZ it could solve my problem? Any ideas of how much would that cost? How about RAM? Should I bump it up form 2 gig to 4 gig?
 
It looks like you have been struggling with this for a while and although I don't have a dual core machine I have experience similar symptoms using ApsectHD and sorry to say what eventually cured my problem was a re-installation of the software.

Also, sorry if I missed this somewhere it appears that you are trying to edit HDV natively with PPro2, before spending money on 10K drives I'd recommend evaluating AspectHD, they have a free trial, I think you'll be impressed on how well it works on your dual core system. Although AspectHD does not use the CPU for editing the way that editing HDV natively does, I beileiev you will have very good performance capturing the HDV from your FX1 [maybe even realtime].
 
Surprise surprise. I found out that SD footage is jittery too. There's something REALLY wrong with this picture and I don't know why. I have to pin point what it is because I can't afford right now to buy a new graphic card, 3 ghz of dual memory, 2 gig of aditional ram. I just bought a mic and a Brevis35 and that kind of blew my budget a little bit. I HAVE to pin point what's wrong so that I can buy ONLY what I need (even though I wouldn't mind at all doing a massive upgrade).
 
Oh yes! Finaly! Sweet! I changed the Tranfer mode to "Ultra DMA 6 - Ultra 133" on the device manager. I don't even know if this is the best options that'll make the HD go faster. All I know is that now I can preview HDV real time at maximum quality, baby!!!

Click to expand...

where did you change this, in bios or in Windows (where is it in windows)
 
right click on "my computer", then go to properties, hardware, device manager, IDE ATA crontrollers, double click on the HD you want to adjust and do it. Befor I did it I ran a speed test and the speed was like 2.0. After I changed the to Ultra DMA 6 the speed was like 160.
 
Okay, I am having a similiar problem- The HD footage is jittery.

i am running a AMD 64 dualcore with 4gig dual channel, with 4 200gb SATA RAID'd together. There is nothing wrong from a hardware standpoint.

I am using Raylight to get 720 24p native in... I've tried the custom settings walkthrough by Raylight, and I've tried it at both 23.976 and 24.0 frames.

I tried to change my ATA controller, but it is set to SATA 1.5g, so I don't need to change that. It is not allowing me to press the Test Speed Button however...

ALSO, could this be because I am not running a system drive? Normally I have a HDD for the OS, and then a RAID array, this is the first time I've had the OS on the RAID.

HELP! I'm about to drop Premiere because of this... I shot something time sensitive on the HVX in 720 native 24p and was hoping to cut it as such.

Sorry for the long thread-jack... but it seemed to be the same problem! No need for multiple threads.

TIA!
