Other stuffWhen I animate 2D stuff I use Anime Studio Pro and I've written a few tools and scripts to enchance my workflow. You can download these for free on my site AnimeStudioScripts.com.
For video related calculations such as aspect ratios and time codes go here.
To quickly make numbered things (such as webpage links in the form of 'image01.jpg', 'image02.jpg', 'image01.jpg' and so on) you can use this tool. Hard to explain but I use it a lot.
A similar tool but with lists of files or strings instead of sequential numbers go here.
