Using animation for batch export is a useful trick. Notice that often (always?) you end up with a duplicate of the last image.
Also, there is a bit of a technical (not really technical, more like bery unlikely you'll come across it) bug in the way shadows update from scene to scene. If you have geometry that hides and shows from one scene to the next and your scenes don't have shadow information turned on, but you have shadows themselves turned on, then the shadows won't update correctly. If you think you might be in that category, I can explain better and I have a little model that shows how it works (or rather, how to see the bug in action).
But batch export is great and a huge timesaver!
Oh and also, you can set your fps and time per scene to whatever is easiest for your brain. So the example given above is great. I tend to set 1 second per scene and then 1fps.
