<p>I'm a total amateur at this video stuff.  I'm actually a web developer trying to create a video for work and I've run into a problem.  Hoping those of you who know stuff about videography can help me out. All of this to say, I apologize for the ignorance that follows:  </p>

<p>I have video/audio recorded as .wmv and another video recorded as .mov.  I'm trying to overlap the .wmv audio with the .mov video.  It syncs up at the beginning of the video, but a few minutes in and it's off.  I have not cut the video yet except to line it up at the beginning.  I've successfully made a couple of basic videos like this in the past but I suspect it has something to do with the two different formats. I'm using Adobe Premiere Pro.  Google has no advice for me.  Does anyone know what I can do to fix this?   </p>

Where did the videos come from?  There are a number of different possibilities, but without knowing more about how the files came to be, it is hard to narrow it down.

I recorded the .mov video in photo booth. I recorded the .wmv in windows movie maker.
