Despite being a live action director John has 18 years hands on experience of CG. Originally, he
used previs for complex effects sequences only - now he prepares
whole films as a matter of course. Agencies and
producers see a fully rendered, animated cut of the film before
shooting even begins.
Blocking, camera moves, track & crane
positions, even focal lengths are decided beforehand, maximising
budgets and leaving more time on set for rehearsals,
refining lighting etc.
Here are just some of the advantages:
- Experimentation with angles and moves can be
done off set - at leisure. The coordinates
are then quickly transferred to the stage or location.
- Agencies
and producers can approve sequences before hand, reducing the need for time consuming discussions
on set.
- The art department know to the foot how much set needs
to be built.
- Grips know exactly where to lay tracks and the optimum
position for a crane.
- Motion control sequences can be set up
in less than half the time.
- Previs eliminates the need for "just
in case" equipment and lenses.
- The need to shoot coverage
is greatly reduced.
- The effect of real world sun positions on exterior
scenes can be simulated eliminating shadow issues.
Previs doesn't
limit creativity - it enhances it. What would a close up look
like on a 300mm from the gantry? The chances are you're not going
to keep everyone waiting for twenty minutes to find out. With
previs John can check out any whim in a few minutes, away
from the set. And previs doesn't preclude spontaneity: if a better shot
suggests itself on the day then he simply goes for it. Nothing
is lost.
