I can say from experience of my own and others, that people usually keep these close to their chest, I consider mine a bible. In fairness, its a tool, so what you do with it is up to you. It's really hard to organise a standard library for even video work as each source is always a bit different, given the amazing community aroudn questions and answers I suspspect nobody wants to have a standard the same as ImageMagic.. It really is a different beast.

Edit : With certain frames, certain 'standards' settings would not result the same, so.. It's really impossible to have 1.

You might have 1 clip which requires 2 entirely different settings.
