get_normalized_clips
Normalize multiple video clips in parallel by adjusting resolution, frame rate, codec, and compression parameters to ensure consistent media quality.
Instructions
Normalize multiple video clips in parallel by adjusting resolution, frame rate, codec, and compression parameters.
Parameters: input_video_clips (list[str]): should give input video clips in the form of string resolution (tuple, optional): Target resolution as (width, height). Defaults to (1280, 720). frame_rate (int, optional): Target frame rate. Defaults to 30. crf (int, optional): Constant Rate Factor for quality control (lower = better quality). Defaults to 23. audio_bitrate (str, optional): Target audio bitrate. Defaults to '128k'. preset (str, optional): Encoding speed vs. compression efficiency preset. Defaults to 'fast'. max_workers (int, optional): Number of parallel worker threads. If None, uses os.cpu_count().
Returns: list: Sorted list of file paths to the successfully normalized video clips.
Notes: - Runs normalization tasks in parallel using ThreadPoolExecutor. - Includes a progress bar (tqdm) to track processing status. - Automatically determines the number of workers based on CPU cores if not specified. - Skips clips that encounter errors but continues processing the rest.
