I installed Premiere Pro CS5 in a new Dell Vostro 470 64 bit Intel Core i5 3450 CPU @ 3.10 GHz with 8 GB RAM, Windows 7 and an Nvidia GeForce GT620 display card. When I first play video on the timeline it's fine, but after a few seconds it plays jerky and stutters and continues like that. My video plays smoother in my old computer in CS4. What's up?
Hard to say, without more information... read & reply...
The Dell site shows an i5 CPU and only one hard drive... what is your configuration?
Does your nVidia card allow hardware MPE?
What KIND of video are you editing?
If HiDef, your i5 may not have enough power
HD video: mpeg2 (I have the same issue with mp4 videos). PPro is installed on my SATA C: drive. The video and project are on my SATA E: Drive. I don't believe my Nvidi GT620 allows hardware MPE. When I begin playing the video it's fine but after about 10 seconds it hesitates, the audio buckles, and it becomes jittery. I changed the display playback quality, but the same thing happens in full quality, 1/2 quality and 1/4 quality.
That's unlikely as my older AMD Phenom 9600 Quad Core 2.3 GHZ, 4GB Computer with Win XP plays videos better in CS4.
Without further details, that is about as worthwhile a remark as saying that a 50 year old Beetle drives better than a Chevvy Volt.
The answer surely lies somewhere else than underpowered hardware. It MAY be some hardware issue, glitch with compatibility or something, but there's nothing in the performance of your setup to cause stuttering like that.
Limited CPU, limited RAM. limited GPU, no hardware MPE, possibly an ill-tuned system, and unclear source material (MPEG2 and MP4 does not mean very much, since they are containers) all add up to questions, which are not answered.
You mentioned audio buckling. What kind of soundcard are you using? Maybe a FireWire connected one? ASIO-drivers tend to make my playback stutter every once in a while. Booting them up (choosing Premiere Pro WDM Sound and the choosing the ASIO driver again) solves the problem. When this happens, both audio and video stutter really bad.
What about his older setup that plays fine? What about the fact that the same stutter happens even if he reduces the playback quality? Sounds like a software issue to me.
He does not mention whether this is the same source material he has problems with now, he only talks about playing some undetermined material with CS4. Playing and editing are different animals.
My guess is that it is a combination of hardware and software problems, but without details it is only guessing and since the OP shows a distinct reluctance to divulge details, all we can do is wait for him to supply the responses asked for.
The symptom described is a buffering/caching issue. The related items to this are ram, cpu, HDD, and or application in background that is causing a delay in the data caching from the drive. 8 GB ram is low for HD material with CS5 or higher. If you have Multicam enabled this creates far more load/allocation with the ram which means you will reach the 8GB limit much quicker. If the CPU usage is extremely high then the interrupts required by the application for memory management will not happen in the time required to playback every frame in a 1 second period of time. If you have a antivirus or internet security application running in the background with real time protection enabled, that will cause the delay of files caching in a correct amount of time required to playback clean.
My Nvidia GT620 does not normally allow hardware MPE, however I altered it so it does allow hardware MPE.
The Nvidia driver date is 2/17/12 and the version is 188.8.131.5285. When I try to update it it says it has the newest driver.
The video is XDCAM EX 720p. I have not tried to play this on my older computer.
Please download the latest driver at Nvidia's website:
When you run the installer select custom and on the next page check mark the clean install I believe it's called. See if the playback is any better at that point.
I did a clean install with Geforce driver 184.108.40.206 from 5/15/12. No change. But here's what I did notice. The jittery video usually doesn't start until I've had PPro open for a while. AND the same jittery playback occurs with simple 720x480 avi files!
