I figured I'd try asking this question a bit more simply.
I have a file that I used in previous project successfully, that when i drag and drop it into the editing area of a new project in Vegas, the 40 minute + video appears to be only a few seconds. I've tried removing any sfk files in case they had some information, but no change. I've even copped it to my PC from the source again and it still behaves the same.
So what could cause a file to appear as only a few seconds when if I open it in VLC or something it clearly is the whole in tact 40 minute video?
At this point if I need to reset Vegas to default or something to clear any potential information it's retaining on this video I'm happy to do that, I'm just at such a loss...
