I'm working on a Multicam edit that consists of 5 DSLR cameras, and a sony-something that recorded AVCHD.
Having upgraded from CS5, I was used to the previous way of syncing everything, nesting it, enabling Multicam and getting on with the edit.
So after syncing all the cams, I thought I'd check what's new in CS6 and discovered you can create a multicam sequence right from the get go. The thing I can't figure out for the life of me, is how to make that work for angles with multiple clips - there seems to be only one sync point for everything. Most tutorials and videos I've seen seem to ASSUME that you only have one video track per camera angle. Life would be lovely if this were the case, but we all know that most multicam shoots can have more than one clip per angle due to card swaps, or more commonly the 4GB recording limit on DSLRs. So even doing it 'song by song' or something may not work as DSLRs can stop/start at various different points.
So there I am, with 74 different video clips for 6 angles that I synced up and no idea how to get them into a multicam sequence in their synced form, apart from going about the nesting method.
The reason I'm curious about this, is because I've had real bumpy playback doing things the old way. So from my synced up sequence, if I took that and nested it, enabled Multicam and used the MC window to edit, I get smooth playback for 15-30 seconds before it really starts to lag, which is driving me nuts as I have to keep pausing, go back and try again until I lose realtime playback again. This is after making sure that the AVCHD track is rendered and everything - the only other thing I could think of to ease things out is to try to make this track into a H264 clip, replace the AVCHD and see how that goes, but I don't have time to waste with test workarounds. I also can't find a way to lower playback quality in the multicam window to ease this cutting.
I'm working on an iMac 3.4GHz Quad with 16GB RAM, so it's not the slowest machine around.
Also, and maybe this is the first thing I should know - is there an actual difference between a nested sequence on which multicam is enabled, and the multicam sequence you create out of the bin - or is the latter just a really simple shortcut? I can imagine that it could be the same, in which case I don't need to worry about the first question above, but I can also imagine that perhaps the old method of nesting struggled with more than 4 cameras and that the new multicam sequence is better optimised for more than 4 cameras- I really don't know.
So to recap:
1) Is a nested-multicam-enabled-seq. the same as the 'create multicam sequence'?
2) How can you create a multicam sequence with multiple files for the same angle when there's seemingly only one sync point for everything?
3) How can I ease up multicam playback with different formats and multiple cams - like changing playback quality, etc?
Thanks for your help!
