VideoPoint

Video analysis is a process in which position and time data are collected from digital videos.

During the process, you click on an object seen in a video. The software records the position and time of that point and advances the movie to the next frame. The process is repeated on subsequent frames. When the process is complete, these data are available in tabular or graphical form. You can then perform simple or advanced analysis of the data, e.g. velocity calculations, curve fitting, etc. Logger Pro software has basic video analysis, but advanced video analysis capabilities are available in VideoPoint™ software from Lenox Softworks.


Important advanced features of VideoPoint include:

  • Fixed, moving, transformed or multiple coordinate systems
  • Angular measurement
  • Polar and Cartesian systems
  • Scaling features; e.g. fixed, adjustable, or multiple
  • Scales that change for zooming cameras
  • An extensive library of videos that can be analyzed, including videos from NASA, Hershey Amusement Park, wave motion on stretched springs, air-table movies, etc.

VideoPoint Capture

If you decide to record and analyze your own movies, VideoPoint Capture software simplifies capturing video from digital sources and converting them into analyzable movies. VideoPoint Capture is compatible with most video capture hardware on both the Macintosh and Windows platforms. With this powerful software tool, real-world movies can be captured by your students, and then analyzed using Logger Pro or VideoPoint.

Important features of VideoPoint Capture include:

  • Elimination of most instances of frames dropped during the capture process. (It also lets you know when you have irregular time steps.)
  • The ability to get rid of duplicated frames created during video capturing.
  • De-interlacing of video to get 60 fps which is great for movies of projectiles, toys or sports. (This assumes that your hardware captures both even and odd fields.)
  • The ability to make a frame rate correction. (If the original video was shot at a rate other than 30 fps and then transferred to a 30 fps video, you can correct the frame rate to get the correct original times.)
  • The ability to eliminate extra frames generated when movies are transferred to digital video.
  • The ability to add annotations and images to video frames.
