Adobe Premiere Pro CS3 Playback Issues
I was having playback issues with HD footage in Premiere Pro. I am editing on a Dell desktop with 3GB memory and a mediocre video card. HD footage played back laggy and skippy, in the source monitor even when I reduced the quality to ‘Draft Quality’. After monitoring the CPU while HD footage played back in Premiere Pro, I determined that the CPU, couldn’t handle the HD footage (it was pegged at 100% each time) I bought an NVIDIA GeForce 8400 GS 512MB 64-bit DDR2 video card to offload the CPU the HD footage was using to the GPU on the graphics card.
After installing the card, I started Premiere Pro and tried to playback footage, but I found that it was still using the computer’s CPU to play the HD footage and wasn’t forwarding it to the GPU on the graphics card. Can anyone tell me how to forward the HD footage to the GPU on the graphics card in Premiere Pro? Thanks.

3 things,
1, What format is your footage? MPEG2? MT2? If it’s uncommpressed footage it will never play smoothly.
2, Try doing anything that would cause you to render the footage, like add 1 click of contrast or brightness to it then render. Sometimes HD footage does play better after rendering.
3, You really should add more ram, as much as you can in fact, but you should at least have a total of 4GB for HD.
Let us know how that goes.

I am using footage converted from .MTS files to HD MPEG2 footage.
I tried your suggestion concerning rendering and it works really well. Plays smoothly but whenever you make an edit or a change the footage completely unrenders.
Let me know what you think. Thanks for your reply.

Yeah, that’s the deal with rendering, you’ll need to re-render after any change to the clip or clips, but that is the case even with SD video in PPro.
As cheap as RAM is nowdays I would really try to add more for faster and better results.
