Q. What about software?
A. You can montage in iMovie, which is a very simple program. It works fine for YouTube and things like that. The problem with using a DSLR to produce HD video is that you can't just put a toe in the water. iMovie is fine for very low-res, and the next step is a big step up. Say you want to make a high-res video: To put it in a nonlinear editor like Final Cut, you'll have to transcode the file. H.264, the compression codec that Canon uses, will work native in iMovie but not in Final Cut. It will work in the latest version of Premier, though I don't have personal experience with it or with Premier Elements. Final Cut Pro is not all that easy to use, but you can learn it in a few months. I started with Final Cut Express for four months, but that was a mistake because you can't just upgrade from Express to Pro.
