I just tried the following:
[pix_film] | [pix_texture] | [pix_coordinate]
... Which doesn't work. Does anyone know why?

...sure, that's not the correct ordering: in general you can think of [pix_film] and [pix_texture] as being book-ends, so you use the other pix_* objects in between...[pix_film] is producing one frame from a movie: a pointer to this frame is then handed between intervening [pix_*] objects, which can then perform operations on/with it...this occurs until hitting [pix_texture], which takes the pointer and uploads it's associated data to the graphics card...you can still play with the data at this point, but you need to use vertex or fragment programs, and this is pretty experimental in GEM atm (ie. no examples)

I just tried pix_coordinate between pix_film and pix_texture and that seems to have no effect either.

...ok,
...small correction on my part: [pix_coordinate] indeed goes after [pix_texture]...however, you also need to then add a geo (something for the texture to be place on)...
...btw: have you tried the help file (help/pix_coordinate.pd)? It works just fine here using 0.90...what platform are you running on/what version of pd/what version of GEM? What effect are you looking for in the first place?
good luck, james
