Choppy HD

Why is my HD playback choppy? If I select a 5 sec HD clip, drop it in the time line, and render it, that new file is choppy to.

My Camera is the Canon HG10. Clips come out as 1440x1080, 29.970 fps interlaced. 48,000hz Stereo (stereo downmix)

My computer is keep very clean with only anti virus running in the start up. Clean up and defraged monthly. Its a 3.07 Gigahertz Intel Celeron with 1024 gb ram, Bus Clock 133 mhz, 200gb 7200 rpm internal hard drive.

When selecting project properties, I go with HDV 1080-60i (1440x1080, 29.970 fps)
With Preview quality of Draft (quarter)

The Canon HG10 is an AVCHD camera, your 3Ghz Celeron is nowhere near fast enough to play back the footage smoothly. Even dual-core and quad-core machines are barely fast enough.

You might consider transcoding the footage to a Cineform intermediate or check into the either the VASST Gearshift or Upshift programs.

We edit on Dell XPS 420 with quad core, 4GB ram and RAID0 hard disks and HD is still choppy to edit, playback is fine. Its all disk usage mainly. Even with 4GB the pagefile is heavily hit so I moved that to a seperate hard disk. Smooth as a babys behind. Unless I use a lot of FX plugins or magic bullets. Then it goes to pot.

You really need more ram. As I said, 4GB still isnt enough and 1GB certainly isnt.
