Defaults
| Option | Description |
|---|---|
| Preferred Subtitle Language / Second Choice | Priority when subtitles are chosen automatically; can be System Language or None |
| External Subtitle Size | Applies to SRT, ASS and WebVTT files and live subtitles |
| Load External Subtitles Automatically | When a video starts, looks for SRT, ASS or WebVTT files with the same name and loads one in your preferred language, unless embedded subtitles are already on |
| Translate Subtitles To / Show Original with Translation | The translation appears above a smaller original line, using on-device system translation |
| Online Subtitles | Find subtitles for each video with OpenSubtitles |
Online subtitles
- A built-in key is included, so it works right away. Enter your own API key for a separate request quota.
- With an OpenSubtitles account, daily downloads count against your account; the password is kept only in this device's keychain.
Adjusting while playing
- Choose embedded or external subtitles. Blu-ray picture subtitles can use Show as Text (on-device, offline recognition), after which size, style and translation work.
- Style presets: Standard, Classic Yellow, Boxed and Minimal; background, outline and shadow are adjustable.
- Sync Subtitles Automatically: adjusts timing to the dialogue. Local videos analyze the whole audio track; remote videos listen to three minutes of dialogue while playing. If it isn't right, adjust Subtitle Delay by hand.
- Translate Subtitles: shows "Translating N of M", starting with lines near the playback position.
AI subtitles
- Settings → Playback Settings → AI Subtitles, or Generate AI Subtitles / Generate AI Subtitles for This Season in the player's subtitle panel.
- Dialogue is recognized on this device and nothing is uploaded. Generation keeps going after you leave the player, and the result appears in the subtitle list marked "AI".
- Speech recognition must be allowed in system Settings.
- Save Next to the Video: also saves an .srt file in the video's folder so Apple TV and other players can use it. Existing subtitle files are never replaced. Apple TV can't recognize speech itself, so this is how it uses AI subtitles.
Danmaku
Settings → Playback Settings → Danmaku. You can adjust the display area, density, size, speed, opacity, blocked words and Simplified/Traditional conversion. If comments run ahead of or behind the picture, adjust the timing; it is remembered for that video. Danmaku is fetched only for what you play and kept on the device for a few hours.
