I just picked up a used Zoom Q3HD and need to use it for a small bar gig this weekend. I tried it out last night for the first time on the HD 720/30 setting at practice. Video quality was better than my cell phone, sound quality was surprisingly good, but file size was huge. What I'm looking to do is to record a few songs and load them up to youtube, facebook, etc...to promote the band. I'd appreciate any tips on how should I set up this unit in terms of video setting HD or WVGA, which one, and about the audio - PCM or AAC, Lighting, and any other tips you can give me.
