Play a video with correction for radial distortion

If a video is recorded from a calibrated system in Shogun Live, it contain lens calibration information. This information can be used to show the video without radial distortion.

To check whether a video contains lens calibration information:

  1. From the View menu, select Video Properties.
  2. In the Video Properties dialog box, look for properties starting with LensDistortionCalibration, like those shown in this example:


    If you find these properties, you can choose to view the video with or without distortion, as described below.


To apply distortion or to view the video without it:

  • From the View menu, select or clear Correct Radial Distortion.

Play back a video with different gamma and saturation values

If the video payload is a Bayer format, you can change the gamma correction and color saturation values that are used for playback.

To access these settings:

  1. From the View menu, select Video Settings.

  2. In the Display Settings dialog box, view and/or change the gamma correction and/or color saturation.

Troubleshooting Vicon Video Viewer

Video playback is too slow

  • On the Playback menu, point to Decoder, and make sure that Hardware is selected.
  • On the Playback menu, make sure that Skip Frames is selected.
  • Make sure that the video is stored on a local drive and is not open over network file-sharing.
  • Move the video to the fastest local drive, ideally an SSD.

Error when opening a video

  • If the video was recorded from a Vicon application, it is likely that the file is corrupt. If the problem persists, contact Vicon Support.
  • If the video was not recorded from a Vicon application it is likely that the file is an unsupported format. Consider using an alternative tool such as VLC Media Player.
