We would need information on your system, CPU speed etc,

Also, try disabling any antivirus and other background programs, especially anything from Norton.

- Drop your preview quality.

- When previewing transitions or effect use dynamic ram preview (mark in/out the area you
want to preview then press shift-b.... that area will load into memory for full frame playback)

- Get a faster cpu

The other missing information is what type of video you are previewing. This is actually more important than CPU, etc. I can get full-speed preview of NTSC DV video on an eight-year-old computer with a P3 processor operating at 450 MHz. On the other end of the scale, people on this forum who have multi-core, brand new computers still report choppy playback when trying to preview AVCHD video.

So, what type of video are you trying to preview?

In addition to the hints already given, here are the ways to increase the fps on your preview:

1. Change to "Draft" or "Preview" for the preview quality.
2. Turn off "Scale Video to fit" and also "Simulate Device Aspect" (right-click on the preview window to access.
3. Make the preview window smaller. A smaller window gives you faster fps.
4. Pre-render the video.
5. Use proxies (if you are trying to edit AVCHD).
6. Temporarily turn of fX (the button is on the preview window).

Tried all of those others. Can make the rame rate jump up to if I make the preview window the size of a thumb nail.

How do you use proxy's and what about gear shift from Q Vast. Does that solve anything.

I use regular DV and AVCHD. Only got slow with 7.0 My PC should be plenty fast I would assume.

You're WAY too underpowered for avchd.
