Frequently Asked Questions

Why should I burn the VTT on my MP4 file?
There are many reasons why you should hardcode your VTT file on your MP4 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 VTT or other subtitle files, so merging the MP4 with the subtitles is the only way for you to have captions on your MP4.

How will you merge the VTT and MP4 files?
The subtitles from the VTT file will be added at the bottom part of your MP4. 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.
