The first full commercial that I shot with Vision 2, the opening
sequence tasked it's flexibility a bit :-)
The
sequence as she walks across the platform into the train consists
of 17 motion control passes of crowd against green screen.
This
was mainly for crowd replication but also so that we could have
a semi-transparent crown with out heroine being the only solid
person.
The crowd passes were shot and TK'd at 6 frames to give us motion
blur and our heroine was shot at 30 frames to make her more
elegant.
Interestingly enough we tested the bedroom sequences
at a whole bunch of speeds, easy with hard disk video assist,
and found that she looked best at 29 fps, there was a very noticeable
difference between 29 and either 28 or 30.
If only the video assist had done half frame speeds!
The transition from location train to studio bed was lined up
using the HDVR and mixing back and forth, We were also hugely
helped by the fact that whilst we were shooting the studio
sequences first assistant Justin went out on the tube and measured
the height of every grab handle around, he also photographed
them
with his phone/camera and emailed them to me in the studio.
Isn't technology grand when it works!
We had a few problems in post but only because I'd assumed that
the editor knew what he was committing himself to when I said
that this is 2K, we can use 1K here etc. Unfortunately he didn't
realise the amount of data that this approach would produce
:-)
Well, the opening shot alone was 34 passes, we
had to do each layer twice, once colour corrected for the look
we wanted and once for the best green screens!
