Thanks. It seems like this bug has been occuring for a long time now. Why hasn't the patch come yet? This is a really big error. I feel Adobe should have sent out an update sooner. Has anyone found a workaround?
Refer to the link Jim posted for additional details. We're working on getting out a fix ASAP. We apologize for any inconvenience.
Ok, I think I figured out a workaround. I haven't had to use it yet, but I think it will work.
1) Make a sequence where you place all clips on the timeline lined up (I mark In points to sync). So Cam A (or 1) is on the bottom and the Cam D (or 4 or whatever your last camera) is on top.
2) In the Project window, select the clips and "create multicamera source sequence" and sync by In points.
3) Drop the multicam sequence in a new blank sequence.
4) Go back to original timeline and put the timecode filter on the top clip and make the "Timecode Source" to pull from "Media".
5) Go to the sequence with your multicam in and drop the timecode filter on that, but this time, set the "Timecode Source" to generate and enter the starting timecode that you generated in step 4.
6) Duplicate the multicam layer and unable the one you won't switch angles on. Make sure to cut both video tracks if you're cutting for content.
So, if Premiere decides to go whacky on your multicam footage, you can at least replace the multicam sequence by:
1) Enabling the clip with timecode.
2) Going back to the original sequence and copying the individual source clips.
3) Drop them above the multicam sequence with cuts and the unabled multicam sequence for timecode.
4) Use the multicam text to replicate the cuts and angles.
This is really, really, really time consuming, but at least it's better than telling your Producer that there is a delay on the project until Adobe fixes their software.
What do you think? Does this workaround make sense?
Or, Plan B: Use Avid.
