VP14 Audio Out of Sync

I made a video of me and my friend playing a game over skype, my recording program wasn't recording my voice, so I put my voice into audacity and I would just sync my voice to the video. I went on to the game and did random things, like click a button while saying "One" then I click another thing, "two" and so on.

I sync up the audio to the video perfectly.

But when I let my video and voice play by it's self from start to finish, it starts to drift off and become unsynced.

For example, the sound waves in the audio file isn't synced up with the actual audio.

Example 2, I have some of my voice audio cut to improve the quality, except my voice at the end of some of these aren't synced.

 

But If I play the video from where I speak at a certain moment, then its perfectly synced, then it's starts to drift off from that point.

Is there anyway to fix this?

It sounds like your media was recorded with a variable frame rate (VFR). Very common with screen capture software. Audio drift is common/normal with VFR video in video editors. This is because the Vegas timeline is constant frame rate. The solution is to transcode the media to a constant frame rate.

Video players do not have this issue because they do not have a timeline which is constant frame rate. They just display each frame for the time specified in the file. Players do not have multiple tracks and such for mixing media.

Thank you for the feedback but, I'm still very new to Vegas Pro and video editing and I don't know how I can do that, if you can provide and explanation that would be outstanding.

Is that the result after rendering or just in preview? The files / formats and plug-ins could be forking up the preview. Confirm that 'Match media settings' has been set in Properties as well.

It's both, when I play it from start to finish it drifts, when I render and save the video it drifts.
