- Why did my champagne birthday video fail?
- Usually the safety review. The models check the photo and the finished clip: a photo can be flagged by moderation, some models refuse photos they classify as real people (in our logs Seedance 2.0 Mini, Seedance 2.5 and Wan 3.0 all did this occasionally), and a clip that shows a real champagne brand, a logo or a copyrighted character can be blocked by the copyright check. Ask for a plain bottle with no label, keep the clothes plain with no logos, and try a clearer photo or another model.
- Do I lose credits when a generation fails?
- Eligible new verified accounts may claim up to 5 welcome credits for 7 days after human verification, while the promotion budget is available. This can cover a low-cost image, not a guaranteed free video. New video generation requires sufficient purchased credits or eligible bounded unlimited capacity.
- What photo works best?
- A sharp, well-lit photo of one adult with the face clearly visible, waist-up or full body, so the bottle fits in the frame. Seedance 2.0 Mini takes JPEG, PNG or WebP up to 30 MB, 300–6,000 pixels on each side. Heavy filters, sunglasses and big logos on clothes make a refusal more likely.
- Can I add the song from the trend?
- Not inside the generator. With sound on, the model makes its own audio for the clip, but it cannot add a specific licensed song. Download the video and add the track in TikTok’s or Instagram’s editor.
- Is champagne birthday AI free?
- Eligible new verified accounts may claim up to 5 welcome credits for 7 days after human verification, while the promotion budget is available. This can cover a low-cost image, not a guaranteed free video. New video generation requires sufficient purchased credits or eligible bounded unlimited capacity.
