Frame the Winners Circle for the shape it was built for

Browse Source 
The stand was composed to be looked at from a 4:3 pod monitor. On a 16:9
canvas its platform runs out at the sides and the shot fills up with sky
and void, so the podium is now pillarboxed: the scene renders into a
centred 4:3 viewport with the surround left black.

The projection has to use the cropped shape too, or the scene comes out
squashed into the narrower viewport instead of cropped by it.
RP412PODIUMASPECT overrides the ratio, 0 turns it off.

The camera also came in closer, from 33 units rather than 45, and now
aims slightly below the group rather than above it. That tilt is what
buys back the sky above the grandstand - aiming above the group tips the
camera up instead and walks the winner's spot off the bottom of the
frame, which is the one position that has to be in shot.
