Then, it’s better to be safe – you can always switch on displaying the embedded graphical subtrack in both desktop players like VLC and some third-party iOS ones like AVPlayerHD. While Subler’s OCR support is excellent, there still might be cases it recognizes something wrong. Note that, in this article, I pay special attention to including both the textual (OCR’ed) subtrack and the original graphical bitmap-based subtitle track. For example, for Finnish, you’ll need the fin.traineddata file.Īfter this, if you open / import MKV files containing bitmap subtitles (unless you manually override the default “everything should be OCR’ed”), the subtitle tracks will be OCR’ed and exported as textual. traineddata to ~/Library/Application Support/Subler/tessdata (after creating the directory). To activate it, for non-English languages, just copy the file.

Today, I’ll speak of a fairly new and really excellent feature of Subler: optical character recognition to quickly recognize (Optical Character Recognition – OCR for short) the subtitles in bitmaps – that is, the default subtitle formats of DVD’s, Blu-ray discs and DVB broadcasts.
