Playback stuttering on Vegas Movie Studio 10

Hi guys,
I have Vegas Movie Studio 10 Platinum and I am currently editing various scenes for a short film that I am shooting. One very short scene is a thirteen second time-lapse of a sunset over a motorway. To achieve this, I filmed continuously for about 45 minutes at 1/2 shutter speed in MOV format (at 30 fps). I then used Vegas to compress the shot down to speed up the playback into 22 minute clip I then went through the clip on Vegas and, at about every 2 second intervals, edited (cut/copy) each frame. When I had 390 frames (13 seconds) evenly cut from a 22 minute clip, I achieved a really nice time-lapse. I then rendered the time-lapse so I can simply import this onto the timeline when I'm editing the short film.

However, I am a bit considered with one thing. When I rendered the time-lapse, I rendered it into a MOV format clip because footage from the rest of the short film is gonna be recorded in MOV format. Being so impressed with how the time-lapse came out, I went to view it on QuickTime and when I press play the time-lapse seems to stop and stutter during the playback on QuickTime. It usually takes about 4 or 5 attempts before the playback in QuickTime runs smoothly without any stuttering. I am concerned now that this stuttering may cause me problems when I import it and render the entire short film project. My question is this: Is the stuttering caused by my computer not being fast enough to play it back on QuickTime for the first few attempts OR is it because I didn't render the clip correctly on Vegas?

Has anyone else had problems similar to this?

By the way, I don't have any playback stuttering when viewing the clip on Vegas. It only happens when viewing it on QuickTime.
 
What settings did you use to make the new MOV file? Most likely something at a much higher bit rate and thus the stuttering in QT.

On a side note I don't get anything to play smoothly in VMS10 on my i7 920 machine. Everything plays smoothly in QT and Splash Lite but there is something goofy going on with Vegas for me. When I add 4 or 5 Event FX to a clip it plays at 3 - 5 fps.

Cheers,
PEte
 
.mov can mean anything. It's just a container. What matters is the codec. What did you use, and what codec is the footage? (What did you shoot on?)
 
I shot the footage on a Panasonic GH1 (unhacked) at 720p in the .mov format. My concern is will this stuttering problem affect the overall outcome of my short film when I try to render the complete project? I can always try rendering the time-lapse again using different settings to see if that could sort the problem. If the problem is the settings, what would be the recommended settings?
