I just recently upgraded to Vegas Pro 17 (was using 13) and am experiencing a strange intermittent problem. When importing video files created with Nvidia Shadowplay, some of them are coming in with the audio at a shorter duration than the video portion. I have recorded hundreds of videos using Shadowplay and have never had an issue with any other program including Vegas 13. In fact, I can import these same files into 13 and they are perfect. I can play the videos and the audio is in synch perfectly. But in Vegas 17, a 30 minute video will have something like 29:50 in the audio track.
I found a couple of tips online to stretch the audio and bring the two back into alignment but they didn't work. It seems as though the desynch is not happening in a linear fashion and the only way I've found to fix it is to spend an insane amount of time chopping the audio into small pieces and lining it up. I did that once, I'll stop using the software before I do it again. Anyone have any ideas to try and fix this? I'm completely baffled and this is happening with about 25% of the video files I'm importing.
