I'm using Apple Compressor and want to change NTSC to PAL. My question is about rate conversion. After applying my settings, the frame size is changed but should I always go into the Frame Controls and change the rate conversion to "so source frames play at 25.00" instead of leaving the default "set duration to 100% of source? I'm thinking yes but I just want to make sure before I spend the time converting. Does this also apply to all other format conversions as well?
