Seedance 1.5 is the Seedance 1.5 Pro model from ByteDance, released in December 2025. It is a video-generation model that specialises in believable, photoreal footage — and in particular in natural human movement, where many models produce a floaty or rubbery look. On Twin AI you can reach it from one interface alongside 30+ other image and video models, and switch between them without juggling accounts.

That focus on realism makes Seedance 1.5 a good default when the subject of your clip is a person: a portrait that starts to move, a walk cycle, a gesture. Where lighter models drift or warp faces, Seedance 1.5 aims to keep motion grounded and physically plausible.

Strengths

• Photorealism. Seedance 1.5 is built to make clips look filmed rather than rendered, with convincing light and texture.
• Natural human motion. Its standout trait is realistic body movement, so people in your clips walk, turn and gesture the way you expect.
• Strong image-to-video. With an Elo of 1254 for image-to-video (versus 1174 for text-to-video), it is at its best when you feed it a starting frame and let it bring the scene to life.
• Reliable for people-first shots. It is a dependable pick whenever a human subject has to carry the clip.

Price and speed

Seedance 1.5 is priced around $5.93 per minute of generated video — a mid-tier rate for the quality it returns. On Twin AI you spend credits rather than paying a foreign bill, and you pay for the finished result, so there is no charge for a render you decide not to keep. That makes it comfortable to test a couple of framings before committing to a final one.

How to use Seedance 1.5 on Twin AI

1. Go to /create/video and choose Seedance 1.5 from the model list.
2. Write a prompt, or upload a photo to use image-to-video for the most lifelike motion.
3. Generate. From Russia it works with no VPN, and you can top up with an RF card or SBP.

For the best results, start from a clear, well-lit photo and describe the motion you want — the more you lean on its image-to-video strength, the more natural the movement.

Alternatives

If you want the newer top-tier successor, Seedance 2.0 pushes fidelity and cinematography further. For a cheaper, faster draft engine from the same family, use Bytedance Fast.
