My question is, I need to know how to over-dub sounds together.. or is that even possible on this program? Cause, I recorded myself alying guitar, and its in a video format. I want to know if I can over dub the soubnds together as one, and is there anyway I can maybe.. make a split-screen for the viewing of the video?
You can adjust the volume of both in the tools like trashed said.
My suggestion to you would be to make the video and add one set of audio then create the movie file, then go back in and add the other. Make sure you have the loudest volume possible with the first audio becasue you will loose some when you make it into a movie and you can adjust it the second time around.
The other option would be to get another program to mix the audio in and then add it.
