Audio description, done for you

Every video, described for people who can't see it

VIDIO writes the descriptions, fits them into the pauses and reads them in a natural voice. You stay in control of every word.

Narration in the pauses

Descriptions are read where nobody is speaking, and the original sound dips under the narrator.

On-screen text

FAQ7

Frequently asked questions

Audio description is narration that tells blind and low-vision viewers what's happening on screen: actions, who appears, scene changes and on-screen text. It's read in the natural pauses, so it doesn't talk over the speakers.

VIDIO transcribes the speech to find the pauses, detects scene changes, and looks at frames from each moment. An AI model writes a short present-tense description sized to each pause, without repeating what's said. A natural voice reads each line and the original sound is lowered while it plays.

Standard fits every description into the pauses; a line that's a little long is read slightly faster. Extended pauses the video on a frame when a description needs more time than the pause allows, then plays on. Extended audio description is what WCAG 2.1 success criterion 1.2.7 (Level AAA) describes.

WCAG 2.1 success criterion 1.2.5 (Level AA) asks for audio description of prerecorded video, and the U.S. ADA Title II rule and the European Accessibility Act refer to WCAG-based requirements. VIDIO helps you produce the description track, the WebVTT file and the script. It doesn't certify compliance: review the descriptions and check what applies to your organization.

Yes. Edit the text or time of any line, delete lines, or add your own at any moment. Add the names of the people in the video and a note about it, and VIDIO can rewrite the descriptions with them.

The narrated MP4, a narration-only MP3 track timed to the video, a WebVTT file for a player's text track of kind "descriptions", and a plain-text script with times.

Yes. Videos up to 1 minute can be described for free and downloaded with a watermark. Exporting without a watermark costs 0.11 credits per second of video (66 credits for a 10-minute video). You pay once per project; exporting again after more edits is free.

I tried your compositing software and I think it is terrific! It works really well in the preview that I did. Blown away, actually.

Such and amazing and fast way to get your video stabilized without the need of having a beefed up PC.

Finally, I can edit like a professional without spending crazy amount of money on software I don't know how to use. Highly recommended for those who are wanting a quick and easy way to remove backgrounds from video.
