Explore the complex challenges faced by law enforcement agencies when dealing with image and video evidence in this 59-minute webinar presented by Dr. Martino Jerian. Delve into the intricacies of forensic video analysis, examining issues such as infrared footage interpretation, lens distortion, perspective tricks, color fidelity, and compression artifacts. Learn about proprietary video formats, image enhancement techniques, and the importance of proper evidence processing. Discuss the impact of artificial intelligence, deepfakes, and cybersecurity on forensic analysis. Gain insights into correctly working with image and video evidence, understanding guidelines, and recognizing the limitations and potential of forensic video analysis in law enforcement applications.

WHY THIS PRESENTATION?
WHAT IS FORENSIC VIDEO ANALYSIS?
WHY IS IT SO HELPFUL?
WHAT ARE THE ISSUES
VIDEO EVIDENCE SEEMS EASY, BUT IT'S ACTUALLY EASY TO GET IT WRONG
INFRARED: DON'T TRUST THE COLORS OF MOST CCTV FOOTAGE AT NIGHT
ANOTHER EXAMPLE
LENS DISTORTION: CAMERAS MAY CHANGE THE SHAPE OF THINGS
PERSPECTIVE: SIZE COMPARISON MAY BE TRICKY
COLOR FIDELITY IT'S HARD TO OBJECTIVELY EVALUATE COLORS ON VIDEO
WHAT COLORS DO YOU SEE?
COMPRESSION ARTIFACTS: HIDING OR ADDING DETAILS TO THE SCENE

The course would have been much better if the modules would keep their completed symbol without having to go back and re-mark it several times each. The content of this course is very good, just the actual mechanics of the site is where it could be better.
