Extract Subtitles from DVD? Is It Possible?

Q: "Hi guys. I convert my DVD to DivX and I know that before ripping I can select to rip with a subtitle track. But I want to have a DivX (*.avi) file and a subtitle (*.srt) file separately. Is it possible to extract subtitles from a DVD and save it as an SRT file? How?"

Different from the text-based subtitle file in MKV, MP4, and other digital videos, subtitles in DVDs aren’t text but actually encoded as raster graphics. The subtitles you see on a DVD are streams of image files which appear one after another. Therefore, exporting subtitles from DVD is a process of extracting graphic subtitles with a method called Optical Character Recognition, or OCR to identify and export the graphic subtitle as a text-based subtitle file. Though it sounds complex, you can easily get this job done with some powerful DVD subtitle extractors. The following illustrates how to rip subtitles from DVD step by step. Keep reading.
