Auto Jimaku Subs sɣur Melonoone

Auto Jimaku Subs helps Japanese learners and anime viewers find, load, clean, display, and sync Japanese subtitle files from Jimaku directly over web video players.

Features:
- Detects anime title and episode information from supported video pages.
- Searches Jimaku using English, romaji, and Japanese title variants.
- Shows a selectable list of possible Jimaku subtitle files.
- Parses SRT, ASS/SSA, and VTT subtitle formats.
- Supports both custom page-overlay subtitles and Firefox native captions.
- Works in normal playback, fullscreen, and Firefox Picture-in-Picture when native captions are enabled.
- Includes timing controls for +/- 0.1s, +/- 0.5s, and +/- 5s.
- Includes line alignment tools for syncing subtitle lines to the current video time.
- Includes best-effort smart auto-sync for subtitle files that start too early or too late.
- Saves subtitle offsets per title, episode, and subtitle file.
- Includes customizable subtitle appearance settings such as font, size, weight, color, outline, shadow, position, width, and background.
- Includes optional hard-sub covering settings for videos with baked-in subtitles.
- Includes subtitle cleanup modes for Japanese-only and mixed-language subtitle files.
- Supports opening the control panel from the in-video button, toolbar icon, right-click menu, or Alt+J shortcut.
- Stores the user’s Jimaku API key locally and includes key testing and clearing controls.

Requirements:
- A Jimaku account/API key is required.
- Subtitle availability depends on Jimaku’s database.
- Subtitle quality, language, and timing depend on the subtitle files available for each anime/episode.
- Auto-sync is best-effort and may still require manual adjustment for files with different cuts, openings, recaps, ads, or unusual timing.
- Picture-in-Picture subtitle support uses Firefox’s native caption handling, so styling may differ slightly from the page overlay.
