Problem

[вαℓυ]

Hey guys, I got a little problem and I wasn't really expecting to get it. I downloaded a 720p .mkv video and I wanted to cut a specific part from the video and upload it to youtube but I ran into some trouble, I found out that I can't import mkv files into vegas. I open up Total Video Converter and convert the video to H264 Avi High Quality, the quality is intact but the audio appears to be out of sync, the audio is 1-2 seconds late so that didn't work either. I tried everything lol, I tried using a program called MKVExtractGUI, AVI-MuxGUI ect. but none of these worked. I wasn't really expecting this to be this complicated, I mean, I just wanted to upload a video to youtube with good quality. Can anyone please help me do this somehow lol? Help will be much appreciated, thanks in advance guys.

Lock the video layer in Vegas of the movie you converted and then slide the audio to the right place until it's synched, then unlock the video layer and voila. ;P
