multiplane or bipack ?

People refering to bi-packing usually mean double exposure. Assuming that's what you meant, it means rolling back and undeveloped negative and shooting additional material on it.

Look at some of John Hubley's for this, "Moonbird", for instance uses some of this technique. In other films he would paint on paper and bottom light giving a similar.

Multiplane is a physical set up where artwork is placed on different levels of glass and photographed.

Both create visual depth. In a multiplane this is done physically. "BiPacking" it is done on the film itself.

Either way, use AfterEffects if you want to do it today.

Humm, your post is way better than mine. I just getting lazy and do not wont to type. Oh fahrenheit, that link I posted has a picture of the machine richard told you about. Take a good look at it, it is very unlikely that you will ever see one in person. Ah the good old, bad, or whatever days.

bipack

—n. Photog.
two separate films, each having an emulsion layer sensitive to a different color, held together with their emulsion layers facing for simultaneous exposure through the back of one.
