Frequently asked questions

Is it really free?

Yes — completely free. No credit card, no trial period, no watermark. Create an account and start generating videos immediately.

What video format do I get?

You get a 1280×720 MP4 with H.264 encoding — the standard format accepted by YouTube, Instagram, TikTok, and LinkedIn.

Can I use this for product explainer videos?

Yes — write a script describing the feature or workflow, and the system builds a narrated video with matching stock footage and captions.

Will it show actual screenshots of my product?

No — this generates video from stock footage matched to your script's wording, not screen recordings, so it's best for narrative/explainer content. Pair it with your own screen recordings if you need literal UI demos.

Can I create a new video for every feature release?

Yes — each release note or changelog entry can become its own script and video, so announcement videos do not bottleneck on an editor's availability.
