http://ubuntuforums.org – I want to film a patient walking to analyse his gait. The reason for this is that we make artificial limbs and the walking should look as normal as possible. For this I need to place 2 or 3 cameras with USB or Bluetooth connections around the patient. On the computer monitor I want to see see the images side by side be able to record the videos for later playback be able to stop at any time be able to step forward/backwards frame by frame view still pictures of the movie the images Any suggestions about which software to use?
