BioMovie Video Analysis software allows users to insert a perspective grid into a video taken from a stationary camera to measure distances and speeds within the video frame. The software's Target tool tracks a subject and provides numerical data on their position, speed, acceleration, and distance traveled over time that can also be displayed as a moving graph overlaying the video.

- 1. BioMovie Video Analysis software Measure distances and speed in tennis using the Target tool and the Perspective Grid tool The video should be clear and the camera on a tripod We insert a perspective grid
- 2. We drag the four corners until they coincide with the field. We indicate the lengths of two sides of the grid
- 3. Now moving the mouse in the grid we get the perspective coordinates at any point on the grid
- 4. We use the Target tool that tracks the subject. The dots give indications on the position and on the speed of movement (distance between the dots) Obviously the data can also be shown in numerical form. In the data pane we see: • Average speed • Instantaneous speed • Acceleration • Progressive distance traveled
- 5. • Position in perspective coordinates The same data can be shown in the form of a moving graph superimposed to the video More information at: http://www.infolabmedia.eu/
