To shoot the commercials professional
puppeteers were puppeteering a real pint of beer on sticks within
the model sets. Three Perception Digital Video Recorders (PVRs)
were used for the live action shoot. One for video assist, one
for sound playback and one to record a second (usually overhead)
viewpoint using a budget video camera. All towers were triggered
from the Milo so that the first frame on film was guaranteed to be
in the correct place. This was vital for the puppeteer to create the
right "performance" for the pint of beer with the dialogue
and sound effects and of course to get the lip synch perfect. The
PVR video assist was triggered so that the first frame on film was
the first frame on video. The animators then used this footage as a
background to animate lips, arms and legs for the pints of beer.
(Being pints of beer they obviously don't have any eyes!)
The animators stepped the live action video assist information
forward a frame at a time and lined up a green "pint" to
the real pint of beer from the live action. The green pint was
merely an armature for the animated mouth arms and legs, the top and
bottom of which had to fit exactly to the live action pint. An
offline cut was done in one of Aardmans Avid suites as the animation
progressed and the director was able to tweak the commercial as each
new animation pass was added. Since the PVR was synched to the film
camera it was known exactly which frame on the video assist
related to each frame on the negative. And so when a frame count
came from Avid to start animating to there was never any worry about
having the background correct. The overhead video camera gave the
animators a hand in showing which way the pint was leaning which was
not always obvious from the front. Post production was done in one
of BBC Bristol's suites and the animation was placed on the live
action and the result was walking, talking (and often dying) pints
of beer.
