Now normally, the Canon XSi doesn't do video, but thanks to EOS Camera Movie Record, that is no longer true.
The downside is you have to be tethered to the laptop while shooting. But thats better than nothing. Check it out over here. There's a nice video tutorial by NottinghamJazz over on YouTube.
Its very easy to use. Just connect the camera via USB, start the software, and hit record. You'll be looking at it through LiveView. I'd reccomend focusing manually and shooting in Manual mode "M" for consistency, or "P" if you just want everything done for you.
Set the proper mode |
One last note: It also turns out its a lot harder to manually focus than you would think.
