Ensure proper boolean checks and optimize the test function.
The test for the grayscale property should avoid direct equality checks against boolean values. Instead, use the truthiness of the value for a cleaner and more Pythonic approach.
- assert video.grayscale == True
+ assert video.grayscaleAdditionally, consider adding assertions to ensure that the grayscale property toggles correctly between True and False states, affecting the shape as expected.

Implement robust error handling in grayscale setter.
The setter for the grayscale property lacks error handling, which could lead to issues if an incorrect type or a null value is passed. Consider adding type checks and handling potential exceptions to ensure robustness.
