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 this show real exercise demonstrations?

No — video is built from stock footage matched to your script, not footage of you or a client training. It's best for explaining programming logic and common mistakes in words rather than exact-form demonstrations.

Can I make a weekly workout-tip series?

Yes — each tip or mistake becomes its own short script and video, a proven way to post consistently without filming every session.

Can I share a client transformation story?

Yes, with permission — write it using anonymized or approved details as a script.
