Now, start recording with your camera or webcam. It's okay if there is some extra time at the beginning of the video, that can be trimmed off relatively easily. Once the video is recording, press record on the software and record your bass along with the track you're playing along to. This way all of the sound is clear and you can adjust the level of your bass vs the backing track. Export the track to .wav or .mp3. Now open the video file in Windows Movie Maker, or whatever you've got, import the audio track and align the two so that they are in sync. Trim off the extra video at the beginning. Upload to YouTube and wow the masses with your low-end prowess.
This post has been, by far, the most helpful of all for me.
I've actually been able to do most of what was said here but I've come to a bump in the road: I've got my video and audio recorded, but I don't know how to "export the track to .wav or .mp3".
I'm assuming this is an essential step in getting the audio into my video editing software (I'm using iMovie) because the Garage Band file isn't recognizable...
Any suggestions on how to export the track to .wav or .mp3?
Thanks for the help so far, regardless.
UPDATE: Ha, I actually just figured it out via a short YouTube video. Gonna try an import both audio/video tracks to iMovie a nd see if I can make this happen...
