Otherwise I am looking at using OpenGL.
It sounds like your images have a lot of transparency to them. You
don't really need to encode this, and if your careful with how you
craft your images and your image sequence you could possibly crop out
a lot of that. OpenGL may allow you more control to do this, but at
the same time your still looking at using a lot of memory to implement
this (especially on older devices that don't have non-power-of-2
textures).
Am I right in assuming that quicktime playback on the iphone does
not support transparency?
Correct.
