Yes the Q3 video is not great quality. Good for getting the idea across for students or local auditions. But if you trying to video a show for a band or do a prominent audition video, it just looks "meh" and nothing is going to change that.
If you can get an iPhone - the video on that is great. The audio isn't even too bad, but the Q3 audio is superb. If you don't have QuickTime Pro it's only $40 and you can sync audio and video on it fairly easily.
Hope any of my 2 cents helped. Let me know if you have any more questions about the Q3 or the sort..
