Problem:
Low quality = too low quality
Best quality = massive file size (hundreds of MB for my current files)
Exporting at low quality appears to compress each frame as an image, whereas best quality appears to export every image at near-original quality. In my case at the moment the result is a choice between a file of 8MB or 450MB, neither of which are suitable.
Solution:
Adopt the strategy that PDF normally uses in programmes like MS Word: User selects level of compression of images and the programme automativally uses vectors and text where they exist to create higher quality file with a smaller file size.
