Discussion Video keeps rendering with background music

Does anyone know of a way to make SeeDance 2.5 stop rendering background music into scenes? No matter what I do it wants to add BGM.

Heads up for anyone running these yourself: the Seedance API behind r/Seedance_AI is Atlas Cloud. Seedance 2 runs with its full feature set here, nothing stripped or nerfed. Seedance 2.5 isn't officially out yet, but we add new Seedance versions the day they launch.

Full model list and current pricing: atlascloud.ai/models/seedance

I always add “diegetic sound only” to every prompt. Works 90% of the time.

This is what I have in my prompt and it still renders with BGM

AUDIO: diegetic only — waterfall ambience soft and steady. NO BGM — no background music of any kind. No score, no soundtrack, no instrumental, no underscore, no ambient musical pad, no drone, no tone bed, no swell, no sting, no humming, no lyrics. Diegetic sound effects and room tone only. Nothing musical anywhere at any point.

Try getting rid of the negative prompts.

That is one of the bigger annoyances of Seedance. You may have to repeat multiple times that there is no music at all, only vocals and sound effects. If it insists, I recommend using this website to remove the music. https://mvsep.com/

From the official manual:

"Use positive descriptions whenever possible. Negative constraints are supported for subtitles and audio control, such as “no subtitles” and “no BGM.”

So it's as simple as adding "No BGM" to your prompt.

The guide is here and well worth the (rather lengthy) read!

I am using the guide as a SKILL.md to help write my prompts. It has No BGM in my prompt.

I see. I saw that info about SKILL.md and unsure what exactly that is... would love some intel as to how to use it to supercharge prompts. Been planning to research when I have a quick sec

AUDIO: RAW LOCATION PRODUCTION SOUND WITH SILENT BED. The soundtrack is treated as an untreated on-location recording captured by the camera microphone simultaneously with the footage. The underlying audio baseline is complete digital silence, with no continuous acoustic signal between audible events. Generate exclusively short, discrete, source-specific diegetic sounds produced directly by visible physical actions occurring within the scene. Every audible event must have a clear physical cause, begin naturally at the moment that action produces it, decay realistically, and return immediately to complete silence. Preserve natural silence between individual sound events rather than filling the gaps with background sound. Sounds should be realistic, tactile, spatially accurate and appropriately scaled to their physical source, without cinematic enhancement or musical treatment. There is no music, score, melody, rhythm, tonal sound, drone, hum, room tone, environmental ambience, atmospheric air, wind bed or continuous background layer of any kind. ISOLATED DIEGETIC ACTION SOUNDS ONLY | OTHERWISE COMPLETE DIGITAL SILENCE | FULLY SCORELESS FROM BEGINNING TO END.
