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 agencies use this for client deliverables?

Yes — the free tier has no watermark, so output is usable in client work as-is, though you should confirm it fits your specific client contracts and creative standards.

Can I manage videos for multiple clients from one account?

Each project is created and tracked independently in your dashboard, so you can run multiple client scripts through in parallel.

Is this a replacement for our video editors, or a supplement?

It's built for scripted, stock-footage-driven content — explainer and social clips, not full campaign production — so most agencies use it to absorb overflow rather than replace bespoke editing work.
