This issue is devoted to the possibility of recording short video clips directly to your computer using digital SLR cameras Canon EOS support LiveView. For this reason the program, which is located here, a brief description there. Video goes without audio codec - MJPEG, frame rate of about 22 fps (depending on your computer), the resolution depends on the camera, the 450D - 848x560, at 40D - 1024x680, at 1000D - 768x512. The resulting file - it's easy recruitment LiveView without obraboki (and / or conversion) in a container avi, why such huge files are obtained. 

If suddenly someone wants to join in the design, write here, the truth may have to go to the branch programmistskuyu forum. 

For many, this makes no sense, "zerkalka should remove the photo, actually, I think, agree, the program was created to balovstva, but because users have appeared, then it is necessary to (ie, too baluyutsya) 
The author tested only on the Canon EOS 450D, but it turned out, that works well on the 40D, 1000D. At the 50D and 5D Mark II does not work. 
Already saw the view of some people, that can burn matrix, I think it is not, because in the Canon EOS Utility (in LiveView), we see the same video, only without the possibility of recording. In any case, the program is supplied "as is" without any warranties, use at your own risk.
