    After Importing File, Audio Stutters 20 Minutes In, then Begins Repeating Initial 20 Minutes

      I imported a 1-hour file that had been previously captured from an HDV camcorder. The file plays perfectly in other media players.

      After importing (and indexing/conforming), the audio does fine for the first 20 minutes, then it stutters for about 2 minutes (this is at a point where someone accidentally started recording at the middle of full tape before being slapped and stopping). After the stutter period, it then just repeats the first 20 minutes of audio through the remaining 38 minutes of video (almost twice more).

      Why? And what can I do to resolve this?

      Thanks in advance.

          Assuming this is a tape camcorder and not an AVCHD camcorder and that you captured over FireWire, it could be a resource issue. Remember, HDV has over four times the video information that standard DV has, and it's highly compressed -- so that puts a lot of demand on your computer.

          Without knowing how fast your computer is, how much RAM you have, etc., it's hard to say if this is the case ... but, with an hour of HDV on your timeline, it had better be a pretty hot machine (and ideally not a laptop) to handle that kind of workload!

          Also, if you're using Vista, you'll need to optimize the operating system so that it doesn't waste resources on things like the Aero interface and the sidebar, etc.

            Yeah the 1-hour file is 11 GB with an average data rate of 3.1 MB/s, so you think the PC itself is causing the issue? This particular computer is definitely not a workhorse, but it does meet the minimum reqs, for what little that's worth.

            Regardless, the only reason I question the theory is because I've tried it three times and the issue happens at the same point every time. Also, I've been working on other things on the computer while it imports the file each time, so the computer's workload has varied each time. Does that change your opinion at all?

            Let me know. Thanks for the input!

              Sorry. Without more information about your hardware, camcorder and software, I can't help.

                  With that operating system on that processor, you may not have enough power to handle more than a few minutes of HDV video, b.

                  I assume you've at least got Vista stripped down so that it can run on a Pentium.

                  But I'll leave that up to someone who has more experience with HDV on Vista to check in with his thoughts.
