I'm new to this and would really appreciate some help. I'm trying to export a 1 hour long recording of a play so that I can burn it to DVDs for the cast. I will be using iDVD for the burning and that seems fairly fussy about what formats it will take. I want to export the film small enough that it will fit on the disks but right now when I use the standard quicktime movie settings it comes out as a 36GB file. Any help would be greatly appreciated.
