That is what I've read. I would love if Canon or Nikon could create a setting that allows auto-restarts of video recording once the 30 minutes are up. And the next file automatically has the last X seconds of the previous file so that I can stitch them smoothly in an editor...

I know that Green Lantern can auto-restart video recordings, but I noticed that it can't really do that smoothly without dropping at least a second of video—at least on my T2i.
