an effect I like is an endless loop of things rolling by, sort of like when the vhold goes out on a TV.

the way i do it now is to use the transformer to multiply a layer, and then the auto-move "in", precisely set to overlap so that it looks like the objects are scrolling seamlessly.
it takes a while to get the controls set just right, so there's no "jump" in the motion.
so I'd like to write a module that does this math at the press of a button and sets it up.

I haven't made any working module yet, though, so any ideas you have might help!

That's what usually is called an "infinite plane" effect. I would like that as well as an infinite rotozoomer, or more numbers than 10 on teh Matrix transformer

okay, an "infinite plane"! but also a setting as an infinite belt, ie:, 1 Y x infinite X.

i think the math would be something like:

distance = ( movie size X scale) / screen size
transformer multiply = ( screen size / ( movie size X scale) ) + 2

for X and or Y values.

As I said it could be an extension on the matrix system, thus being able to increase the number of elements from 10 to infinite in x, y or Z

I use the offset filter in AE

Maybe I can figure this out as a module, we'll see...

(I agree, it would be a cool addition to the transformer itself. a "wrap around" button or something.)
