A new feature in Keynote, Pages, and Numbers, is the ability to reduce the size of your file by compressing images, video and trimming the unused parts of videos. These reductions can significantly reduce the file size of image and video-heavy files. You can also save a draft copy that will be even smaller if you need it.

Excellent video thanks
Big file sizes constantly cause problems I find. I presume the lower size would be carried into an exported pdf? Good one, Maestro.
dally: I would test the PDF idea and see what you get. I'd imagine it would be smaller since it would contain lower-resolution images.
