SupRip Tutorial: From SRT Basics to Advanced Subtitle Editing

How to Use SupRip to Extract and Edit Subtitles Quickly

What SupRip is

SupRip is a tool that extracts subtitles from DVD/SUP (bitmap subtitle) streams and converts them into editable text-based SRT (SubRip) files. It recognizes subtitle images, performs OCR, and saves timing so you can edit, sync, and reuse subtitles.

Quick step-by-step

1. Prepare source files

   • Rip the DVD or extract the SUP/IFO/VOB subtitle streams to a folder (tools: MakeMKV, DVD Decrypter, or similar).

2. Open SupRip

   • Launch SupRip and point it to the folder containing the SUP/VOB files.

3. Load subtitle stream

   • Select the subtitle stream you want to extract. SupRip will display subtitle pages (bitmaps) with timing.

4. Run OCR

   • Start OCR to convert images into text. Check language settings and character set for accuracy.

5. Correct OCR errors

   • Manually review each subtitle line in SupRip’s editor, fixing misrecognized characters, punctuation, and line breaks.

6. Adjust timing

   • Use SupRip’s timing controls to shift, stretch, split, or merge subtitle events to match speech precisely. Play the video alongside if possible.

7. Export to SRT

   • When satisfied, export/save as an SRT file. Choose encoding (UTF-8 recommended) for correct characters.

8. Post-editing (optional)

   • Open the SRT in a subtitle editor (Aegisub, Subtitle Edit) for advanced styling, spellcheck, or batch timing adjustments.

Quick tips for accuracy

• Use a clean SUP source — high-quality rips give better OCR results.
• Set correct OCR language to reduce mistakes.
• Spellcheck after OCR to catch homophone and punctuation errors.
• Compare with audio to fix timing and missing lines.
• Use Subtitle Edit or Aegisub for batch fixes, waveform-based syncing, and visual previews.

Troubleshooting common issues

• Poor OCR results: try preprocessing images (contrast/deskew) or use a different OCR engine.
• Timing off across file: apply a constant offset or use time-stretching tools in subtitle editors.
• Missing characters: save as UTF-8 and ensure font support in player.

Recommended tools

• SupRip (for SUP→SRT)
• MakeMKV / DVD Decrypter (for ripping)
• Aegisub, Subtitle Edit (for advanced editing)
• FFmpeg (for testing subtitles with video)
