Stereo stuff |
|
|
Interested in stereo using polarised light.
I have one Q in case anyone here knows the answer.
If I use two digital cameras do they have to be synchronised, or can that be
done in editing by frame shifting?

If I understand your question correctly, yes, it's fairly easy to
synchronize two separate video sources in post.

The other related Q in that case is: how accurate is the timing on (cheap)
digital cameras?

I'm afraid I have no idea what you mean by "cheap digital cameras." Digital
camcorders sold in the U.S. conform to NTSC standards, which is 29.97 frames
per second. They are very accurate in that, if they were not, you wouldn't
be able to watch the video they produce on a television.
I've synced the output of miniDV camcorders over 1-hour in length without
any apparent drift.

One last point -- if frames are dropped, sync can't be maintained.
This won't be an issue for the camcorder, but can be an issue for the
computer and transfer protocol, i.e. use an OHCI-compliant 1394 port on
the computer, make sure the computer has sufficient power to handle the
data stream and record it to the hard drive, and use capture software
that is sufficiently robust and will report (or, at least, abort on)
dropped frames.
