Fix Seedance 2 and Seedance 2.5 errors

1. Find your error

The message tells you what failed: a picture or file, the prompt, the soundtrack or a setting. Each one has its own fix.

Tip: Change one thing per retry, so you know which change fixed it.

2. Make the picture in Seedream 5

Seedream and Seedance come from the same model family, so Seedance accepts a realistic person made in Seedream. The same person made with other models often gets blocked as a possible real person.

1. 1In the Media Studio, open the Model card, Image tab, and pick Seedream 5.0 Pro.
2. 2Describe the face, the outfit and the place. To fix an existing picture, attach it and ask for the same person.
3. 3Open the result and press Use Image.

A candid photo of a woman in her early thirties behind the counter of a small corner coffee shop in the morning. Olive skin, dark curly hair tied up with a few loose strands, light freckles, a small silver hoop in one ear, calm focused eyes. She wears a rust orange apron over a cream linen shirt with the sleeves rolled up.

She is pouring steamed milk into a cup on the counter. Behind her: a chalkboard menu with no readable words, shelves of jars and ceramic cups, a hanging plant, warm light from a window on the left.

Shot at eye level, natural morning light, soft shadows, realistic skin texture, shallow depth of field.

No text, no logos, no lettering, no watermarks anywhere in the frame.

Tip: Only for people you made up. A photo of a real person, a celebrity or a lookalike stays blocked, and it should.

3. Put the picture in Seedance

The Seedream picture goes in as a reference. The prompt says what moves and what you hear, not what the picture already shows.

1. 1Model card, Video tab, Seedance 2.5 or Seedance 2, References tab.
2. 2Add the Seedream picture.
3. 3Write the camera, the action and the sound.

@image1 is the barista. Keep her exact face, hair and outfit in every shot.

She finishes pouring the milk, slides the cup across the counter toward the camera and looks up with a small smile. Slow push in from a medium shot to a close up. Handheld, realistic, morning light.

Sound: the hiss of the steam wand, a cup set down on wood, quiet cafe chatter.

No subtitles, no text, no watermark, no logo.

Tip: To animate one picture on Seedance 2, use the References tab. The Frames tab on Seedance 2 needs two pictures, a first and a last.

4. Describe the music, never name it

Seedance makes its own soundtrack. When it sounds like a known song, the whole clip is stopped.

1. 1Take out song titles, artist names and real lyrics.
2. 2Describe the genre, the mood, the tempo and the instruments.
3. 3Keep Include Audio on.

Music: slow, warm lo-fi hip hop with soft brushed drums, a mellow electric piano and a round bass line, quiet under the room sound.

Tip: Turning the sound off does not fix it. Describing the music does.

5. Pick a language it speaks well

Seedance 2.5 speaks 11 languages: Chinese, English, Spanish, Portuguese, Japanese, Korean, Indonesian, Malay, Thai, Vietnamese and Arabic. Seedance 2 is safest in Chinese and English.

1. 1Write each spoken line in the language you want to hear.
2. 2Name the language before each line: In English, warm and calm: "Here you go."
3. 3Keep each line in one language. Names and brands are fine.

Tip: Romanian is on neither list. Make the clip without dialogue and add the voice in Text to Dialogue.

6. Stop subtitles, logos and face drift

These go wrong without an error, so the prompt has to prevent them.

1. 1End the prompt with: No subtitles, no text, no watermark, no logo.
2. 2Use one clear, front facing picture per person.
3. 3Pick a landscape ratio when you can. Portrait clips get burned in subtitles more often.

Tip: Generate shows the cost before you press it. Fix the prompt first, then render.
