All of what I'm going to describe is all using the same computer, same camera, same memory card, same card reader, etc.
That's what makes this such a mystery.
Ok -- here's the procedure I (always) use... Take video using camera. Put card in card reader. Save clip to computer. Import into win mov maker. Edit etc.. "Make" into movie. Upload to youtube, etc.
Now here's the mystery...
Suddenly clips do not have audio component. More mysterious is what could be causing it, because I've tried various things:
Older clips that were saved still work fine (when I now import them into a movie maker project)
New clips that I just made now also work fine.
The clips that do not work fine were all filmed around the same time -- and they *DO* have audio when I play them on the camera, AND when I play them on my comp, when I have copied them onto my comp (form mem. card), AND they play fine after I have imported them into the "collections" section of the movie maker project -- *BUT* as soon as I drag them into the story line>>> NO AUDIO COMPONENT!
I've tried to duplicate the problem + every time, it all turns out FINE.
So what's the (bleeding) difference on those particular clips?!?!
