Same resolution as the MPG video — a 1080p source produces 1920×1080 BMP frames; a 4K source produces 3840×2160 BMP frames. Resize after extraction if you need smaller thumbnails.
Can I extract frames at specific timestamps in the MPG video?

Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one BMP file per timestamp. Useful for chapter thumbnails or scene reference shots.
