Use references with distinct roles: identity, motion and sound. Mark the timestamp of a requested edit instead of rewriting the entire scene. Longer sequences still need review for continuity.
About this domain: seedancenfsw.com is an independent guide. NSFW in a domain name does not mean a model permits adult content or unrestricted generation. NSFW support is not verified here. Check the official model and service policies before use.

With support for up to 30 images, 10 video clips, and 10 audio clips per generation, clear asset organization prevents conflicting direction.
Instead of uploading near duplicate frames, group your image references by creative role: front and side character views, key prop close ups, and environment lighting frames. Keeping lighting color, background clutter, and wardrobe consistent across your still set helps Seedance 2.5 maintain a recognizable subject across up to 30 seconds of audiovisual output and subsequent extension rounds.
Use video references specifically for movement such as camera tracking speed, gesture timing, or transition rhythm rather than competing visual designs that clash with your still images. Likewise, trim up to 10 audio clips so spoken dialogue, musical phrasing, or room ambience is clean and distinct, giving the model unambiguous cues for synchronized audiovisual generation.
ByteDance announced Seedance 2.5 on July 31, 2026 and noted BytePlus API access as coming soon. Because external creative platforms may cap simultaneous uploads below the full published specification, confirm the active input limits, file format rules, copyright permissions, and content policies in your chosen service before assembling a large multimodal reference brief for production.
Image A defines the blue bottle; image B defines the stone surface. Video C supplies a gentle camera slide. Audio D supplies rain ambience. Keep A as the product reference and ignore product shapes in the other files.
Compare the generated bottle against A, the surface against B and the camera pacing against C. Remove or relabel any reference whose role was confused.
