Help covers the upload, the optional note, guest pay-once generation, and what a short credit balance shows. The cookie swarm_session lasts up to 30 days and maintains signed-in access and browser-owned guest orders. It ends sooner when you sign out or the session is revoked. Receipt questions that need a specific payment start as an email draft on the contact page. That page does not send the message.

Before you generate

Upload 1 portrait, up to 24 MB. You do not have to write the dialogue. The exchange is already part of the scene, and an extra note is optional and can be left blank.

The published models are Seedance 2.0 Mini, Seedance 2.5, Seedance 2.0 Fast, and Seedance 2.0. They output video. Lengths are 11 seconds or 15 seconds. The frame is 9:16.

If payment is the question

Press Generate to prepare the request. If you are not signed in, you pay once for that prepared clip and do not register. Approved guest checkout and confirmed payment then start the prepared generation. If you are signed in, Generate spends purchased credits. When the balance is short, the studio shows the gap and the lowest-total-price Basic, Pro, Max, or Studio pack that covers it.

A pack only adds credits to the account. Buying one does not start a clip, and it is not the same deliverable as a single generated clip. Returning from that top-up keeps the photo and settings. Press Generate again to spend the credits on the saved request. Buying credits on their own requires sign-in in the existing purchase modal, and signing in does not place the order. Packs do not renew.

A new account does not start with a complimentary balance. Nothing starts an extra payment or an extra generation on its own.

Confirmed payment starts a prepared guest clip. A signed-in visitor returning from a credit top-up presses Generate again. Buying a pack does not start that clip.

A receipt, a failed clip, or a request to close an account is prepared as an email draft on the contact page. The page does not send it. You review the draft and send it from your email app, or you download it. There is no live chat. Initial response: Within 1 business day of receiving a report. Review and handling: Within 7 business days of receiving a report.
