PatchMaker is a 2D motion tracking program designed for intraframe video editing and compositing. It can determine the motion of a selected object in the scene to a subpixel precision under a specified parametric motion model.
The computed motion can be used to solve the following tasks:
1) Placing a patch on a moving object.
2) Background stabilizing (eliminating unwanted motion in the scene caused, for example, by camera jerks)

DVdriver runs in conjunction with multiple webcam software applications simultaneously. It lets your camcorder act like a webcam that has optical zoom, auto focus, stereo sound, auto stabilizing, night vision, high quality optics, and more, depending on your camcorder. Control zoom, focus, recording, and optionally pan/tilt with your PC locally and over the internet.
