Confirming that SCENE_NUMBER is 1-indexed?

[vedantroy]

Just want to confirm that the format-string in something like this:

        scenedetect.split_video_ffmpeg(
            video_path,
            filtered_scene_list,
            output_dir=workdir,
            output_file_template="${SCENE_NUMBER}.mp4",
            show_progress=bool(os.environ.get("DEBUG", False)),
        )

is 1-indexed.

Correct, the default implementation of split_video_ffmpeg uses 1-based scene indices. You can specify a custom formatter if you want 0-based indices (see the formatter arg and default impl).
