69-75: Consider adding validation for video_fps parameter.The video_fps parameter should be validated to ensure it's within an acceptable range (e.g., > 0 and <= 60).
Consider adding validation:
def load_states_and_record_video(state_file: str, video_save_path: str, video_fps: float = 10): + if not 0 < video_fps <= 60: + raise ValueError(f"video_fps must be between 0 and 60, got {video_fps}") logger.info(f"Loading states from {state_file}")

1-8: LGTM! Well-structured imports and dependencies.
Good practice to import necessary modules and check for MOVIEPY_AVAILABLE flag.
10-18: LGTM! Well-documented test function with appropriate skip condition.
The skip condition and parameter documentation are clear and follow best practices.
42-43: LGTM! Useful main block for manual testing.
Good practice to provide manual testing capability with appropriate defaults.

29-38: LGTM! Robust type validation with clear error messages.
The added validation checks for states and map_def improve reliability and provide clear error messages.

🛠️ Refactor suggestion
Consider using a fixture for test data.
The hardcoded test file path "test_pygame/recordings/2024-06-04_08-39-59.pkl" could make the test brittle. Consider:
- Using a pytest fixture to provide test data
- Creating a small test recording file specifically for this test
- Adding the test file to version control to ensure test stability

Fix typo in parameter name.
The parameter name "vide_save_path" has a typo and should be "video_save_path".
Apply this fix:
-def load_states_and_record_video(state_file: str, vide_save_path: str, video_fps: float = 10):
+def load_states_and_record_video(state_file: str, video_save_path: str, video_fps: float = 10):And update the usage:
- video_path=vide_save_path,
+ video_path=video_save_path,Also applies to: 73-73

17-17: Enhance docstring with return value information.While specifying the file format is helpful, consider enhancing the docstring to describe the return values (states and map_def).
- load a list of states from a file with pickle `*.pkl` format + load a list of states and map definition from a file with pickle `*.pkl` format + + Returns: + Tuple[List[VisualizableSimState], MapDefinition]: A tuple containing the loaded states and map definition
63-66: Add parameter validation and enhance docstring.The function would benefit from parameter validation and a more descriptive docstring.

29-38: Well-implemented validation checks!
The validation logic is thorough with proper error logging before raising exceptions. This will help with debugging invalid state files.

Improve the
load_statesfunction with validation checks for loaded states and map definitions. Introduce a new function to load states and record a video. Remove unnecessary debug logging in theSimulationView. Add pytest for the new video recording functionality to ensure proper operation.Fixes #79
