need to edit 1080p at 24fps - possible?

I need to edit in Vegas (cuts only) 1080p 24fps (actually 23.97) footage created out of After Effects.

Messed around with codecs but cannot get realtime playback on 3.2 Ghz with 2 GB RAM. With Sony YUV and Quicktime Animation codecs, playback stutters as soon as you set preview to anything but "Draft" - however preview window indicates playback is realtime.

I have a Matrox Parhelia card - is it not handling frame buffers from Vegas correctly>

Any suggestions?

Of course you can do this, no sweat.
You're not going to see realtime unless you use the CineForm codec, and even then, 3.2 is somewhat pushing it.
You should be using Preview/Auto for most things regardless, unless you've got a RAID 0 array on a very fast RAID controller, and fast drives in the array.

The Cineform codec does not support 1920 X 1080 at 23.97fps. I do have a RAID 0 with new Seagate 7200 RPM drives.

you can play back huffyuv at 1080p in real time with your setup .. you might also be able to playback picvideo mjpeg ..

BUT - The Matrox Parhelia is a bottleneck .. replace it with a low or med quality nvidia card .... believe me, i like matrox, but getting HD anything to play on a Matrox Parhelia is a waste of time ... specially mpeg2 HD ..

you can also (far quicker) make a proxy file and edit that -- then just sub out the HD file for final rendering ...

Steven,

The Codec licensed for Vegas is an HDV codec, is it is limited to 1440x1080 to match HDV resolution. Connect HD has to same upper resolution. There are no frame rate restrictions -- so if your were to switch to anamorphic pixels -- 1440x1080 at 23.976 would work fine. CineForm does has a 1920x1080 codec (and beyond), although those are current only licensed through Prospect HD and Prospect 2K.

This is correct, in the Vegas version, but it shouldn't matter.
You're working with HDV, so it has a 1.333 PAR, which displays the 1440 at 1920.
[edit] never mind, I hadn't read David Newman's response.
