Configurable dual subtitles for YouTube using original captions and YouTube translation tracks. DoubleSubs: Dual Subtitles for YouTube adds a customizable subtitle overlay to YouTube videos. It can show the original caption track and a YouTube translation track at the same time, with separate font sizes, text colors, background opacity, positioning, timing offset, and quick controls inside the YouTube player. It is useful for language learning, bilingual watching, accessibility, and comparing the original subtitles with YouTube's translated captions. Key features: - Show original and translated YouTube subtitles together. - Use available YouTube caption and auto-translation tracks. - Choose subtitle tracks per video. - Set separate font sizes and colors for original and translated lines. - Show 1 to 5 subtitle fragments at once for easier reading. - Optionally reveal words progressively when timing data is available. - Drag subtitles and the quick settings panel directly on the player. - Toggle DoubleSubs from the YouTube control bar. - Hide YouTube's native caption layer to avoid duplicate subtitles. - Copy a debug report when a video behaves differently. Important notes: - DoubleSubs does not call any external translation API. - DoubleSubs does not translate text itself. - It uses caption and translation tracks that YouTube already exposes for the current video. - Availability and quality depend on the captions YouTube provides for each video. - DoubleSubs is not affiliated with YouTube or Google.
