The useful answers, before you start.
Is BriefVox free to use?+

Can I start with my own video?+
Yes. Upload a supported video, then work with its captions in the editor.
Can I change the caption look?+
Yes. Start with any of the twenty-six styles and adjust the placement, width and size on your video.
Is there a watermark on the free plan?+
