If I understand correctly what you are after, you want to use a
camera-generated real-time mark to sync multi-cams. Right? This is probably
not something Adobe (or any other editing S/W) can fix. Wouldn't one have to
have every camera manufacturer add a new meta data to time-tag, from its own
internal clock, every frame without affecting the video, since this has to
be done before importing onto the computer? And then wouldn't you have to
calculate the time differences between each of the clocks?
Note that slates have been used for years (but they are useful more for
identifying disparate clips than for sync'ing, although I guess they also
work for video). From the term "slate" camera field mixers often have what
they call "slate" microphones intended for recording an sound mark onto a
video audio track.
The best way I know to sync cameras is with the audio, not the video. Every
week I put together something made from 4 cameras (and now for the last few
months it is 5 cameras). The technique I use to allow easy sync'ing is to
feed the same audio to every camera; I avoid on-camera mic's. Using the same
audio stream makes it quite easy to locate patterns in the waveform to sync
on. I look for patterns between pauses and/or for spikes.
I have enough wireless receivers to do this; I use one set of wireless belt
pack transmitters which get audio from a house mixer or a videographers
field mixer. I have 4 JVC's and one Canon 7D and the JVC's can each record
an hour continuously and not slip sync with the audio between them. (If
you're using an external recorder that may not be the case.) The Canon
records shorter clips so I have to reestablish sync with them more often.

Subject: [AP] Real time 'timecode'
Hi All,
Might be a silly question, but, having used recently some multicam setups, I
feel it would be really nice to be able to see (what you never want to see
on finished projects anyway), is the real time actual event TC (minus
frames) in the preview window/project, which will obviously be removed when
you finalise it.
So, as long as all the camera's are (more or less) running the same time and
date, it would become much more easy to sync multicam setups if you could at
least see the 'real time' in the monitor.
I'm not being lazy or anything, its just .MOV files from the Canon 7D mixed
with the AVCHD ones from consumer 'fixed' cams are not exactly easy to play
around with as easy as I'd like them to be.
(Full time busy job kills all the time I have to even view the footage, let
alone mess about with any more steps or editing it with TC in real time.)
Not being able to sync all these timelines seems to be either something I've
overlooked or isn't available in PP 5.
If its not there guys, this could be something Adobe needs to address at
least, its a rare occasion I've done a multicam, but its been a real time
killer trying to sync even when the cards are in order and everything else
is pretty solid otherwise.
Cheers,
Neil.
