After which, they carried on with the hands-on practical training. The training was started off with the analysis of the various images to determine their authenticity in whether they had been modified.

The practical session also comprised of the techniques in Motion Tracking using Avid Media Composer and Frame Averaging using Adobe Photoshop CS6 to reduce the digital noises in the image.

Hence, it was an honorable opportunity for the students to participate in this workshop, gaining an insight to video forensics and how it actually contributes to solving a crime.
