Frequently Asked Questions

Why should I burn subtitles into my MKV file?

There are many reasons why you should hardcode your Subtitles file on your MKV file. Most platforms do not allow you to edit the style of your captions, burning them can be better in some cases. Also, some platforms like Instagram do not accept Subtitles or other subtitle files, so merging the MKV with the subtitles is the only way for you to have captions on your MKV.

How will you merge the subtitles and MKV files?

The subtitles from the Subtitles file will be added at the bottom part of your MKV. The font color of your subtitles will be white with a black outline to ensure readability.

Is there a watermark?

Yes. Videos made with the free tool include a small HappyScribe watermark. To burn in subtitles without a watermark, use the HappyScribe subtitle editor on a paid plan.
