live-action vs animation

As previously mentioned, this is the first time I have worked on a narrative short film in animation. I have previously worked on live-action short films, mostly my own projects. So one of the key questions was how do I take what I know from live-action and apply it to animation? Where are the differences?
Some obvious differences I already knew, like these:

• the image making process happens as much during production as it does in pre-production in live action. In animation all of that needs to be decided in pre-production.
• Animation typically 'edits' before production to save cost and work.
• Because of the above point and the aspect of creation in Animation, Animation tends to have a more intense pre-production.
• In my research for script writing I found that a script for Animation typically has a lot more detail to again lend itself better to the 'creation' aspect.

Because I find that knowing seemingly unrelated things sometimes helps put things in perspective I decided to write a short research based essay on it. Find it here:

Animation in its Relation to Cinema and Other Media

After writing it, I have to admit I'm nowhere closer to understanding the ins and outs of how to different approach and Animation short film as opposed to a live-action one. However, what it did make me realise that a lot of these affected decisions might not actually depend on whether it is Animation or live-action, but rather on what the short film wants to talk about.
I also found that my personal opinion might have slightly changed. I have in recent months developed a conviction that live-action is indeed a form of animation. While I still support that view, I now also think that the beauty of animation might lie less in its defined abilities and more in the fact that it is so versatile that there is no one way to put a definition to it. It allows for a much broader consideration of subject, media, creation and representation.
