- Reads from AVI movie files
- Zooms in or out to any degree
- Configurable automatic marker tracking
- Displays up to 4 video streams
- When in calibrated mode, displays the line of zero residual for the 2nd point given a 1st point
- Allows user-specified video stream offsets
- Change the gamma of the video images
- Load, view and modify previously digitized points
- Export camera view information to Maya
- Requires MATLAB 7 or newer (full or student version), the Image Analysis toolbox is required for marker centroid identification
