This project analyzes video frame differences to detect potential tampering, such as duplicate or frozen frames. Using OpenCV and NumPy, the script compares a tampered video with a real video and visualizes the results.

The script usesframe difference analysis:

1. Convert each video frame to grayscale to simplify processing.
2. Calculate the absolute difference between consecutive frames.
3. Count the number of non-zero pixels in the difference to measure changes.
4. Flag frames with minimal changes (below a threshold) as potential duplicates or frozen frames.

This approach highlights anomalies that may indicate video tampering.
