Hey…didnt solve the prob. I far as I can tell you should have a Mac for HD editing!!!! But its more a software issue for PC’s. Not your computer.
I pretty much load all the files from my xacti into vegas and drop them into the time line in chronological order then I “make Movie” i.e master the whole lot out as one big master video. (probably keep this under a gig in total size) I select the format and template required.
For me its wmv – 4.8mbps HD at 720-24p.
Then I start a new project in vegas and import the movie I just created – you should then be able to edit a lot easier, minimal stutter.
Set your preview tab (above your video preview) to half in all categories Draft, preview, good, best and you should be good to go chopping up and editing away. Depending on how good your computer is..I have a new Asus ‘Centrino 2’ and “Half” preview quality seems to get me by ok…can be annoying but not too annoying.
If you still have problems and its still too stuttery to edit properly even after lowering the Preview tab to “quarter” in all categories you’ll have to speed up your computer or convert your master video to standard definition. which is 3.8 mbps – you shouldn’t have any stutter issue in Standard Definition. (DVD quality)
Hope that helps…;)
