Questions

How much does it cost?

About 400 Sparks a minute. You see the price before anything is charged.

Which plans include it?

Plus, Pro and Team. It is not part of the Free plan.

What do I need?

A clip, uploaded or picked from your Library.

What do I get, and what are the limits?

A new copy of your video, as an MP4, with the descriptions as a second audio track named “Audio description”, or mixed into its only audio track if you choose. A WebVTT file of the descriptions and the narration alone, as a WAV, come with it.

Where does the result go?

It is saved to your Library.

Can I use the results commercially?

Yes. You own what you make from your inputs and can use it for any purpose, commercial use included. Results may not be unique: similar content can be made for other people. Use only inputs you have the right to use, and check results before you publish them.

Will a description talk over the dialogue?

No. A description goes only in a pause, starting just before what it describes appears, and the original sound is turned down under it. A video that talks all the time gets few descriptions.

Can I change a description before it is voiced?

Yes. Switch on “Review the descriptions first” and the run stops once the descriptions are written: edit or remove one, or write one for an empty pause, then voice them. You can also edit a finished run, and only the changed lines are voiced again.
