have you tried the audio analysis?
I do a lot of music videos and it takes some doing to align the video to a separate audio track.
I just bought PD12 to see if it works for me. I have been using Adobe Premiere 10. What I do there is to click on the audio track that is in the video and make it large and do the same with the separate audio track. I then expand the time line so that both audio tracks can be seen better. I then try to see if I can find a place in the video where someone is making a movement that has sound too and try to get the separate audio in line with that, eg someone raises their hand and you can hear the song on the video audio and find a spot on the separate audio where you get that same sound. In Premiere I could highlight a track and hold doen the alt key and tap on the arrow keys to move that track one frame at a time. it takes some doing you can get almost frame accurate. So far in PD12 I see where you can put a time line marker on that hand raising and one where you think the serarate audio is at and then go up to audio analysis and align by menu markers.
this is a rough idea and I hope it may help until someone here can help you more.
good luck and let me know it any of this makes enough sense to help and we can go from there.

Thanks MartyGene1
I haven't got into the audio analysis stuff yet but it's on the short list. I did a quick drum solo type video with a Canon Powershot I had handy. I recorded a separate audio track through the studio mics into my DAW. When I uploaded to PD12 I disabled the camera audio but used it to line up my audio from the DAW and since it's drums there were a lot of dynamic peaks and valleys I could use it worked rather well.
Seems like there should be a better way and I have just yet to get there.

how did you line up the two tracks?
I am working on learning the multi cam editing thing. you could have put the audio and video tracks in the multi cam mode and used the audio analysis from either source to synch them.
I have 3 video tracks and one audio track from an edirol 44 that I have been able to synch all video tracks to. That part is working fine. Where I go from there will be a learning curve...

Here is a Toot that will point you in the right direction.

Toot !!! Perfect!!! Now that is what I can really use. I usually do 3 camera shoots and a separate edited audio track and then once I synch them ( which can take hours) I can begin to edit them. I didn't want to do cuts only like in multi-cam as I often over lap some of the video tracks for effect and doing cuts only wouldn't work that way for me. I also like that way that you put all four tracks in the monitor to see which one you want to use. I usually had to make the upper two tracks opaque to see which one I want to cut out. These features are why I bought the PD12 suite and probably won't use PreEl anymore.
If you have done anymore with this like showing how you cut out unwanted parts or make the parts that you do want to stay in, please let me and all of know.
Way to go Toot !!!
Thanks

I guess I do it the old fashion way. I get the cameras rolling and clap my hands together. That way I can look for that spike in the audio where I clap my hand together. Then after is all line up I remove the camera audio. It does not take me long to line them up. Intel i7 5960X overclock to 4 Ghz 16 GB of ram.

Hey Toot... I am making a music video that is about an hour long. My Sony camcorders cut the files in segments when it saves the video to the SD Card. When I have them in multicam view and do audio with my music track it puts each segment on a different track so I cant figure out how to do what you did in your tutorial in this video ( http://youtu.be/8DtJDjjq8nA ) if I try to put them all in track they go out of synch.
any ideas?

trying to send a picture of how the multi cam editor has put my files on different timelines

Thanks very much Barry! I'll post back here later on what I learned. A thing moderately good is not so good as it ought to be
