I did a "google" to find out what a Dell 780 Optilex is.
I cant see anything that would say it is a multimedia system or is set up to do multimedia work in a NLE.
Correct me if I am wrong and out of line... but why did you choose this machine for the task of editing?
Problems that occur in Premiere's scource or program monitor, but not in players, are often related to the Overlay part of the video driver.
These problems are often - but not always - solved by upgrading your video driver to the latest one available from Dell. OCCASIONALLY, for known cards such as ATI or NVIDIA, there is an even newer one on the manufacturers website, but tread cautiously if taking this approach.
Also try turning off/on GPU acceleration in CS4.
Lastly, video that is corrupt in some way will often play in a player but not in an editing app. For instance I have some corrupt HDV footage that plays like a dream inWindows Media Player, but turns to mush in Premiere. Have you got different footage you can try?
Would you like to post a screenshot of the fragmented video?
Well we didn't actually choose these machines - they were 'supplied' to us
by IT contractors - as we are an educational provider we don't really
have any other option than to use what's provided...
ah. I couldn't help but notice that the vision is image-only (no sound). what sort of device is it from? A flip-cam maybe?
As Harm often points out, an AVI is just a wrapper and can have any-old crap in there, so if you download G-Spot and run it on your footage, what does it say the codec and resolution are? Maybe post a screenshot of that too?
At this stage I'm leaning towards bad driver or bad footage (50 cents each way).
I noticed that your hardware setup is not yet properly finished. First make sure that your system is properly setup, then start using PR.
Thanks for your post - we completed the hardware setup but the problem still occurs...(all other CS apps are running ok the problem seems to be only with Premiere Pro)
Please give us the full specs. of your system, as you have it. Do not skimp on any details. Dell offers variations on most systems, so even with the Web site open, we have no clue, as to what you bought, and how it's set up.
Next, tell us all about your Assets, your source files, and again, do not leave anything out.
Next, tell us about your Project/Sequence Presets.
Next, tell us about things like the Magnification and Quality setting for the Program Monitor.
All of these will be helpful in remotely troubleshooting your issue.
martin, any progress on your problem? where did the footage come from? looks like either bad footage or bad video driver to me.
We have just installed some updated video drivers and that seems to have
finally fixed the problem - thanks for all your suggestions/replies...
