Hello

are you creating your movie or are you using some existing content?

If you are making it, whatever software you are using, when you come to save the movie file, make it Quicktime format using the Apple Intermediate Codec (AIC). This is assuming you are using a Mac to create the content, as PC's do not have the AIC.

If you are using premade content, you will need to convert it to Quicktime using a third party piece of software. There are several programs out there.
