Update check_video.py

[mst-rajatmishra]

Hii,
i have tried making some changes and improvements,

In Check_Video.py

• Used try-except blocks when working with video files to handle potential errors more gracefully (e.g., if the video cannot be opened).
• It might be helpful to print out the properties of the videos for easier debugging or verification.
• Consider adding docstrings to your functions for better clarity on their purpose.
• Instead of using assert, which can be disabled with optimization flags in Python, consider raising exceptions with clear error messages.

In Distortion.py

• Each function includes a docstring for clarity.
• Added checks for parameter values to prevent invalid usage.
• Improved variable naming and formatting for better readability.

Thank You,
Rajat Mishra
