174574 Create Flash Movies

I need a program to create short flash movies, by assembling short samples from a master flash movie file. I want the ability to set the duration of the samples to be taken, and the duration between samples. For example, take a 10 second sample every 2 minutes and 20 seconds. Then, Take all the samples, put them together, create/save new flash movie. I also want to include an intro, and an outtro... and I want a fade effect between each sample/clip. This needs to all be done on a UNIX server.
