Hi,

Cocoa interaction with Quicktime (and also Cocoa and NSImage) seems to be in a real mess.

AFAICT, NSImage uses QuickTime for reading, but not for writing.

NSImage does not allow a way of setting the dpi of an image when saving as a jpeg.

Do not use NSImage. Use NSBitmapImageRep. NSImage is for getting stuff to screen (hence 72 dpi), not for manipulating the representation.
