In-Depth Information
EDL or XML from one of the eyes for conform, so it might not make sense
for you to i x it in editing in favor of having the conform team do the i x.
But it would dei nitely help to let the conform team know that sync has
been checked and what shots have been l agged as out-of-sync. (Maybe
you can even tell them how many frames of offset and in what direction).
If you are providing Left and Right EDLs/XMLs to the conform team,
then sync it and tell them everything has been checked. They will be very
happy to hear it.
3.7.3 Scaling
This is something that editors use all the time to create more dynamic cuts
and better looking shots. But this can be a problem in 3D! As the scale
of the shot goes up, also the disparity between eyes becomes greater by
the same amount. So basically if you are scaling up your shot 50%, you
are scaling your 3D 50% as well. This is particularly troublesome in shots
that have a lot of 3D parallax and if too much, it can render the shot
unusable. Be mindful of this and talk with your 3D supervisor when in
doubt so he or she can be aware of the issue. It all might be i ne or it might
open a conversation about the real need for the scale. In an extreme case,
you  might end up converting the shot to allow the scale keeping the
3D under control. One way or the other, the sooner everybody knows the
better!
3.7.4 Quick Edits
A very generalized misconception is that you cannot do fast cuts in 3D. What
you shouldn't do is jump quickly from something in front of the screen to
something behind the screen and then to the front again. Quick changes of
depth force the eyes to converge at different spots quickly. This muscular
movement, even though is executed very fast, takes a little time to execute
(between ½ and one second, usually) and while we are converging we are
not very aware of what we are looking at. So if you make people re-converge
their eyes all the time they will miss what is on the screen and over time,
get a headache. On the other hand, if you keep your depth more or less
constant through your fast cut, the eyes will remain converged at the same
spot and people will be able to see almost as comfortably as if it was 2D.
Mind your depth!
