Why generation can't be free
One 14-second render is six reference-conditioned storyboard frames plus a full video-model pass with audio — real GPU time on every single order. A free tier would either watermark the output, queue it behind everyone's free renders, or die. So: $9.90 per video, less in packs, refunded automatically if the render fails, and never a subscription.
The truly free route (and we mean it)
If free is the requirement, use the tutorial's prompt with the free trial credits that Veo-, Kling- and Seedance-class platforms hand out. Expect watermarks, queue waits and a backflip that takes three attempts — but it costs nothing, and the walk-through is on the tutorial page. The full comparison of every route, priced, lives on the alternatives page.
