Seedance
Seedance is ByteDance's hosted multimodal video model that turns a text prompt or a still image into a short clip — and generates the audio with it, producing synchronized dialogue, lip-sync, and ambient sound in a single pass. It reads full cinematic descriptions with real camera direction and runs entirely on Civitai, so there's no GPU or install to worry about. Generate a clip, with sound, straight from a description.
About Seedance
Seedance 2.0 is a hosted multimodal video generator from ByteDance's Seed team. It's built on a Dual-branch DiT (Diffusion Transformer) architecture that jointly generates the visuals, dialogue, lip-sync, and ambient sound in one pipeline, natively fusing text, image, and audio inputs rather than treating audio as a separate post step. Weights aren't published — the ByteDance-Seed org is on Hugging Face, but Seedance runs as a hosted model, which on Civitai means you generate it through the on-site generator instead of downloading it.
Two variants are available on Civitai: Seedance 2.0, the full-quality model set as the generator default, and Seedance 2.0 Fast, a speed-optimized variant that trades some fidelity for quicker turnaround. Both do text-to-video and image-to-video and both produce synchronized audio. Clips run from 480p up to 4K native, and the model can take reference inputs — up to nine images plus short audio and video clips — to steer a generation. Because it is API-only there are no LoRAs or local runs; you prompt it directly in the generator.
Choose Seedance when you want video and matching audio in a single generation — synchronized speech, sound effects, and ambience without a separate audio pass. Against a polished closed API like Kling or a fast one like Hailuo you get the joint audio-plus-video pipeline; against open-weight Wan you trade downloadable models and a LoRA ecosystem for that one-pass audio and ByteDance hosting. It runs right here on Civitai either way.
How to prompt Seedance
- Write like a mini-screenplay in natural language, not tags. Seedance follows the order subject and performance → action → camera → lighting and environment → mood → audio. Weight syntax like (word:1.5) is ignored.
- Don't write a negative prompt — Seedance doesn't use them. Say what you want positively instead of listing what to avoid.
- Describe the audio, since Seedance generates it natively: name the dialogue lines, music style, sound effects, ambient noise, or ASMR detail you want synced to the picture. Leaving audio out wastes the model's signature feature.
- Use real cinematography vocabulary over the vague word "cinematic": "Steadicam long take," "push-in," "pull-back," "over-the-shoulder," "macro shot," "slow rotation." Explicit camera technique reads far better than generic quality words.
- Keep a clip to one continuous take — avoid describing multiple hard cuts or sequential scenes. Lean on physical detail ("wet-pavement reflections," "visible breath vapor," "weight and inertia") and performance cues ("solemn," "explosive") to direct the motion.
AI models move fast — new versions ship often, and a model’s capabilities or Buzz cost can change. For the latest, check the model’s own page before you generate.
