GraphicsConverter (shareware) can compile sequential images (over 90 different file formats) into any number of animation formats with various compression schemes. It will output a movie as Animation, BMP, Cinpak, Component Video, DV NTSC/PAL, Intel Video/Raw, Motion JPEG A&B, Planner RGB, PNG, Sorenson, TGA, TIFF, and Video. You just need to use the "Convert" option from the "File" menu. Then find the images & select all of them. Then just hit the radio buttons to fill-in your file formats & compression, frames pr sec, color depth etc. One caveat, GraphicsConverter is MAC OS only so if you know someone with a MAC you'r in business, Or, have your work buy one for you!
