a new way of doing things

as i have researched the making of machinima i have discovered an interesting fact about the making of all animation. in retrospect this is very obvious but it was a thought that simply had not occured to me as i have as of yet only had expirience in making standard live action films. this is the fact that all voice overs must be done before the creation of any actual images (due to having to have the charecters lip sync properly) and because of this editing and filming are efectivley the same thing.
