Made for lessons and channels

Tutorials and lectures that everyone can follow

Viewers who can't see the screen hear the slides, the board and the steps you show, in the pauses between what you say.

Descriptions in the pauses

The narrator reads only where nobody is speaking, with the lesson's sound lowered underneath.

FAQ7

Frequently asked questions

Describe the video with VIDIO and download the narrated MP4. The simplest way is to upload it as its own video, for example "Title (Audio Described)", and link it from the original's description. If your channel has YouTube's multi-language audio feature, you can also add the narration as an extra audio track.

Most course platforms let you upload an alternate version of a lesson: use the narrated MP4. Players that support text description tracks, such as Able Player, can read the WebVTT descriptions file aloud. The script is handy as a text alternative too.

No. Descriptions are written to fit the pauses in the speech, and the original sound is lowered only while the narrator reads. In Extended mode, the video pauses on a frame when a description needs more time.

What a viewer needs to follow along that isn't said out loud: slides and on-screen text, what's written on a board, actions in a demo, and scene changes. It doesn't repeat what the presenter says.

WCAG 2.1 success criterion 1.2.5 (Level AA) asks for audio description of prerecorded video. VIDIO helps you produce it, but it doesn't certify compliance: review the descriptions before you publish, and check the rules that apply to your school or organization.

The descriptions are written in the language spoken in the video, and the narrator voices read many languages. You can edit any line before you export.

Videos up to 1 minute are free with a watermark. Exporting without a watermark costs 0.11 credits per second of video (66 credits for a 10-minute video), paid 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.
