alice-teacher Puzzle Trying To Combine Alice 3 and Adobe Premiere Pro

[Leonel Morales]

Hi!

I think the billboard can be resized instead of moving it closer to
the camera, the effect would be the same, possibly.

Another option would be to place an invisible object, an sphere would
be perfect, in the center of the billboard, exactly in the middle of
the height and width, setting the billboard's vehicle to that object
and the bringing the object to the camera. The thing here is that when
you move an object, Alice usually uses the center of the _base_ of the
object, and this can distort the movement.

One last option would be to use two camera markers, or maybe more, at
equal intervals between the camera and the billboard and then moving
the camera to each of them in order with "begin and end abruptly".

Not sure if any of them will work, but it can be fun to try.

Best!

Leonel
