Problems creating a Multicam Clip

I use Multicam all the time, but this latest project is giving me MANY problems.

I have two angles, a tripod mounted wide-angle, and a hand-held close-up. Both clips are about 26 minutes long. I have edited the metadata to make sure that camera angle is properly identified.

When I try to create the multicam clip (first automatic, and then playing with a bunch of the settings), I get one of two results. Either it crashes (if I try to reset the starting timecode to 0:00:00:00 from 0:00:16:22; or it creates a 25-29 second multicam clip droppping everything else.

Two pertinant pieces of information: the timecode on the wide-angle was off so that the clip starts at about 57 minutes, while the close-up clip starts at 0, and the close-up camera has many instances of excessive shake.

I have a hard time thinking it could be the timecode, since I used audio-sync (and this hasn't been a problem in the past) - so all I can think is that it is the excessive shake causing the problem. My thoughts (which I haven't tried yet hoping to get some informed guidance here) is that I either need to:

1) go into the close-up clip and correct all the excessive shake problems

2) undo the analyze clip (which might involve re-importing that angle), which would remove all the excessive shake warnings - and I would then just visually cut to the wide-angle at those times.

Any ideas? Thanks in advance.
