How much does one video cost?

It depends on the settings. The exact price is on the button before you start, and it updates with every change.

What if it doesn't work out?

If the run fails at the provider, no credits are charged. If the result is ready but you don't like it, press “Edit and retry”: the prompt and settings stay.

Which frame shapes are there?

21:9, 16:9, 4:3, 1:1, 3:4, 4:5, 5:4, 9:16, 9:21. 9:16 suits Reels, Shorts and stories; 16:9 suits YouTube and websites.

from 3s to 15s. Pick the length in the settings before you start.

Can I use my own picture?

Yes: add up to 10 — from your computer, from the Library or as an element. The model takes them as a base or a reference.
