AI Ad Video Generator for Short Vertical Creatives
Test ten hooks instead of one. Each prompt becomes a 5-second portrait clip you drop into a Meta or TikTok ad. 35 free credits, no watermark.
Paid social rewards volume of creative, and filming ten variants is what kills most small budgets. Sisif makes the variants cheap: a 5-second 480p render is 7 credits, so a $10/month plan buys 14 test clips a month. Render the visual, add the copy and the call to action in your ad platform, and let the auction tell you which hook works. Exports carry no watermark.
35 free credits • No credit card required

Prompt tips

- 03 Keep the product or logo out of the render and overlay it in the ad tool so it stays crisp.
