Anybody REALLY knows how to create CDXL anims?

[Animagic]

I want to convert an mpeg I created to CDXL format.

I have the Iff pics (iff24 320x240) ready and numbered correctly.
The sound (Iff sound) is also ready.

The problem is that i cannot find a program to load
the pics and the sound and multiplex them in
a CDXL file.

I tried every program on aminet. None seems to accept iff files.

Please Help!

Chris: Maybe there is a reason why CDXL isn't used much, even on the Amiga?

I suppose ...  :-D
The problem is:
I created the "Team Chaos" logo for the game
Total Chaos. Team Chaos likes it, and we thought
to put it on the game as a startup video.

That's why I must convert the file to CDXL!
