I'm having trouble with the audio. My video is 2hours long and when I upload it into VP, it only has 10 minutes of the audio even thought the download has the complete audio before I load it in. I tried compressing the video before putting it into VP but that didn't work. I tried a couple of different formats but still no luck. Does anyone have any ideas? Borate, you seem pretty much in the know, any ideas?
