Step 4. Compress/Shrink Blu-ray to DVD 9 quality MKV file.

When back to the main interface, click “Convert” button to start compressing Blu-ray to DVD 9 quality MKV. After conversion you can click “Open” to find converted MKV file. The MKV file contains video stream of main movie, Dolby Digital 5.1 track, and selected subtitles.

Tips and Tricks:

1. This Blu-ray shrinking software can save your settings when customizing audio and video parameters. All you need is to click “Save” button and give a name of your settings.

2. You can now straightly burn resulting MKV to DVD. But note that it will be a data DVD and will not work with standalone DVD players.
