How to Extract Subtitles From a Blu-ray Disc


Creating copies of your Blu-ray DVDs -- for backup purposes only -- is a good way to protect your investment in the expensive movie discs. However, when copying a Blu-ray disc, you may encounter errors related to the transfer of the subtitles included with the movie. Some authoring programs merge subtitles into the video stream -- so you cannot remove them when watching the movie -- while others do not copy the subtitle files at all. Extracting the subtitle files from a Blu-ray disc and then converting them to .SRT format ensures that subtitle text will display properly when you view a backup disc.

Things You'll Need

  • Subtitle-ripping program
  • DVD burner compatible with Blu-ray media
  • Download and install a subtitle-ripping application. Sites such as, and offer several programs that allow you to rip subtitle files from regular DVD movie discs as well as Blu-ray media. Notable programs that allow you to rip subtitles are ImTOO DVD Subtitle Ripper, SubRip and VobSub Ripper. Save the subtitle-ripping-program setup file to your computer.

  • Open Windows Explorer on your PC and then browse to the folder where you saved the subtitle-ripper installation file. Double-click the file and then follow the on-screen instructions to install the ripper. Restart the computer if prompted.

  • Insert a Blu-ray disc into your computer's DVD drive -- the drive must be Blu-ray compatible. If the Windows AutoPlay box appears, close it.

  • Launch the subtitle-ripper application on your computer. Click "File" on the menu bar and then "Open VOB(s)," "Import Video Chapters" or another similarly titled menu option. Wait for the ripper application to detect your DVD drive and display a list of compatible video files or chapter folders in the program window.

  • Click and select the video chapter files or VOB folders from which you want to extract the subtitles. Select the language stream for the language you want to use or extract and then click the "Scan," "Scan With OCR" or "Import Subtitles" link. Wait for the ripper application to scan the files, locate the subtitle streams and create word list files. Depending on the length of the video chapters, the amount of subtitle text and other factors, the scanning process might take several minutes or a few hours.

  • Click the "Export" or "Save Subtitles" link or menu option after the program extracts the subtitle text from the disc. Enter a descriptive name for the subtitle text file and then click "Save" or "OK."

  • Click "File" and then "Open" on the menu bar of the ripper application. Open the subtitle text files saved in the .SRT format. Review the text and edit or change it as needed to correct inaccurate scan entries.

Tips & Warnings

  • After you extract and edit the subtitle text files, you can reintegrate them into video chapter files or folders with an ISO-burning application to create customized movie images you can burn to DVD or Blu-ray discs. Programs such as UltraISO, MagicISO and Daemon Tools Professional allow you to integrate .SRT files in movie ISOs, as do many DVD-authoring applications.
