Previous Next



To rip subtitles from a Matroska file:

  1. Create a project with mkv file or change the media to a mkv file.
  2. Go to Tools>Matroska ripper
  3. A new window will show up, select the track you want to rip subtitles from then click ok.
  4. Also a new window will show up, in the left list, select the subtitle you want to change text for.
  5. In the right, enter the text you see in the picture.
  6. Repeat steps 4-5 for the rest of the subtitles.
  7. Click ok.

Auto rip:
Entering texts for large count of subtitles may take long time. Using the auto rip (or as known as ocr) will save time by using image compare technology to convert the sub-picture to text.

  1. In the auto rip section under the text box, change the method you want to use. There are 3 methods:
    Normal: for clear sub-picture subtitles, fastest method.
    None-compressed: for a large sub-picture with small subtitle.
    Emphasis1 as main color, Emphasis2 as background color: this is a very rare situation that I faced with some mkv files.

    How to choose ? if the sub-picture is a clear text image, select the Normal method. If the picture is huge and the subtitle is very small, select the None-compressed method. but if the picture is huge, the subtitle is very small and not visible (usually grayed out) then chose Emphasis1 as main color, Emphasis2 as background color method.
  2. Specify the subtitle index number you want to start from if you want to
  3. If you have a chars matrix file you want to use, click Load chars matrix file button.
  4. Click Start auto rip button.
  5. A new window will show up with the subtitle text, ask you to enter the letter you see in the small box (or the letter you see in the red rectangle), enter the letter then click next or press enter.

  6. The window in step 4 may show again, enter the requested text then click next. The entered letter will be saved for the letter image data and if the next subtitle sub-picture includes the same letter image, it will converted automatically to the letter you entered and sometimes you will not see the window in the picture.
  7. When done with all subtitles, it will ask you if you want to save the chars matrix file. This file is important if you have another mkv file have subtitles saved with the same font. The matrix will make things go faster since it save letter images data and the text that match each letter image.
