Studying video evidence includes the following;

  •  Confirmation footage meets international quality standards and is admissible in court; grounds for challenging validity of the footage
  • Genuine, unaltered images - detecting signs of manipulation, tampering or anomalies like lighting changes
  • Metadata authenticity - time stamps, GPS coordinates, camera settings, and device information
  • Improvements for a clearer picture - reducing frame rate or enhancing image quality to reveal crucial details, including people, objects, sequences or events
  • Still images - extracting frames from the video stream for further technical analysis of what's shown
