The Canon 550d is an excellent photo camera with its 18MP(5176x3456 pixels) sensor, but the main reason that I purchased one was for its HD video modes. It is capable of shooting 1920x1080p at 24, 25 & 30fps as well as 1280x720p at 60 & 50 fps. In order to produce these frame sizes/rates while still using the full sensor area the camera "cheats" by skipping lines. When shooting 1080p for example, i believe that the camera is skipping every third line. The 550d has another video mode which doesn't use this cheat.
It is called Movie Crop Mode which is interesting but in most cases not very useful. Check out this diagram: The part of the image outline in red represents the entire usable pixel area of the 550d. A few notes about this video: The camera has a normal 640x480 mode which is not included in the diagram at the top of the article. Movie Crop is a fun feature to have, but the lack of HD makes it mostly useless.
