On the sound sync issue. I have found that recording the sound from the live shots of the band on the camera then lining you your mastered recording is easy. Lets say you shoot or just going to use the chorus of the song with the live band shot simply drag the mastered sound file so the chorus on the live shot and mastered sound file lineup now your in sync. Naturally this will take some practice until you get use to seeing an audio wave form soon you will be able to notice peaks in the sound wave that match. Preview your video from about for or five seconds before your chorus starts this way your eyes will focus watch the vocalist closely and listen if your synced your done. . If not zoom in and move your sound file the direction it needs to be moved. Keep repeating this step until your in sync.
Now be sure to mute the sound file on the film do not mute the inserted mastered song. Save your file in your chosen format now you have the same sound quality on your video as the pros. Of course the sound quality is only as good as your mastered song file.

Thanks,

Regarding synching the audio and video: Rather than trying to synch the H4 audio and the video, it might have been easier to keep the camera audio, add the H4 audio on another track, synch the two audios and then delete the camera audio.

Versions of the video: Your project had a few objectives which each of which could be better served with slightly different copies of the video. All could be created from the same post-production copy. For examples: A promotional copy could have the band’s name and website across the bottom of the screen during the entire video; An HD copy to be distributed on disk to family and friends; A You Tube copy for linking to the band’s web site; etc.
