Problem in with flow of imported AVCHD video
I have been using the Sony PMB software to trim my AVCHD videos. This is working well, and I save the trimmed clips in AVCHD format to maintian high quality. When I review the trimmed clips both in Sony PMB and using Windows media player, I have a well flowing clip in excellent quality.
I now want to bring clips together into a mini movie. I have Sony Vegas Movie Studio Platinum 9 Build 92 to do this.
When I import any clips, even just 1 into this software and view it from inside Movie Studio, there are portions of the clip that become jerky – like the frames get stuck. When I save into an avi file from Movie studio this jerkiness is still there, yet the original AVCHD clip is still smooth flowing.
How do I get Movie studio to flow this movie better?

I’m only guessing here but PMB really does a great job at previewing clips smoothly. It never fails to do so. However, Vegas unless you have a very fast computer doesn’t preview the same clips with near the speed that PMB does.
I can’t figure out why Vegas can’t use the same engine or whatever it is they use to preview.
If you’re new to Vegas, the only thing to do is set your preview window in Vegas to “Preview (Auto)” -

Thank you for your post.I dont think that it has anything to do with speed of the computer because the spot where the video seems to ‘stick’ is always the same location within a clip regardless of how I import the clip into Vegas. The other reason why I don’t think it has to do with the computer speed is that when I generate an AVI from Vegas, it ‘sticks’ in the identical spot which tells me that somehow Vegas has actualy corrupted the file on importing and when an AVI is created, Vegas is just outputting the file it thinks it has.
Has anyone else seen anything like this? Can there be some sort of setting in Vegas that I dont have set right?

Upon more analysis, I have discovered that Movie Studio actually is adding frames causing this motion to happen.
The video as I view it in PMB is about 500 frames long. Each frame is unique.
When I import the same video into Vegas, I see for example that everything looks fine up to frame 63. And then frame 64 was inserted and is identical to frame 62. Frame 65 looks like it carries on from frame 63.
So when the movie plays at normal speed – say of someone running – the runner is running forward then at frame 64 steps back.
What could be causeing Vegas to add the frame that doesnt exist when I view it in PMB?
