The error message should be more descriptive and include the video path to help users identify which file failed to open.
| print("Error: Could not open video.") | |
| print(f"Error: Could not open video at path: {video_path}") |

This condition should be save_idx > len(selected_frames) or removed entirely. The current logic could cause early termination when save_idx exceeds num_frames, but save_idx starts at 1 while num_frames represents the count.
