Juddery video

[FizzyFizz]

(apologies if this has been asked a million times already, I'm quite new to this!)
I'm not too sure how to explain this but whilst trying to edit video (using Premiere Elements 3.0) the picture often appears to run slow with loss of frames, almost as if it's loading up as eventually it seems to catch up and will run smoothly. Is this to do with not having enough RAM?
I have 512GB RAM with a Pentium 4, 2.8Ghz processor with hyper threading.
If I stuck in about 2GB RAM would this improve video editing much?
Any advice on this will be much appreciated.

How do you transfer the video from the camcorder to the PC, often this happens if you are using USB. Firewire will give no problems, well it has not for me.
Also is the original video steady when you view on the camcorder. I get this on my Sony if I have not run a fresh tape start to end and back using the FF and REW functions, it seems that the tape is tight when it is first used.
If this is the case then no amount of editing will correct it. BUT DO use Firewire (DV out).

Fizzy,

What format are you editing? What camcorder? You had another post asking about SD memory cards... these are generally mpeg format, and "harder" for a PC to edit. And some applications are more efficient at editing DV than others. (I'm not sure how good PE is at this).

RAM might help, but when editing a highly compressed GOP based format like mpeg, it is the need to uncompress this on the fly which is the challange, and that depends more on the CPU.

If it is a DV camcorder, you'll get much better performance if you capture DV from tape via firewire. If it is a SD/mpeg only camcorder, then you can try adding memory, but it may not help. Or try a different editing application more optimised to editing mpeg (like "Womble").

When you have it in the timeline do you have ared line above the footage if so hit the return button and wait for itto render you should then have a green line above it .Each time you as youedit the clip do this and it should run smoother. Notwithstanding the other advice given

[FizzyFizz]

thanks for the replies.... The video is imported from a mini DVD but the actual file I'm working on is already on the PCs hard drive.

Ok - then it is mpeg2 then, which is more cpu intensive.

Per jaymac's comment, it seems Premiere Elements 3.0 can do a "pre-render" to make the editing more smooth.

If the render dont sort it best to export as avi within Pe3 and then reimport pe really only likes avi .

[FizzyFizz]

Thanks for that advice Jaymac.... the rendering worked great. Would the render process be speeded up if I had more RAM?

[jaymac]

Glad it worked more ram not too sure I went down that road first for another Prob in Pe it did'nt help but I do know from experience the graphics card can make a difference to the general running speed' especially if you only have an onboard graphics like Intel Check out the premiere dedicated site at Adobe
