Bring your creative visions to life with the advanced Seedance 1.5 Pro. Experience native audio-visual synchronization, cinematic camera control, and ultra-fast inference speed designed for professional workflows.
Engineered with industry-leading technology to elevate your production speed and video fidelity.
Unlike traditional models that generate audio as a separate post-process, Seedance 1.5 Pro features a dual-branch architecture that generates sound and motion simultaneously. This native alignment ensures that every explosion, whisper, or ambient sound is perfectly matched to the visual frames, creating a highly immersive cinematic experience.
Achieve absolute accuracy in character dialogue. The model natively supports lip-syncing across multiple languages and regional dialects. It maps phonetic cues directly to facial muscle movements, ensuring natural speech representations without the typical distortions or uncanny valley effects found in other generators.
Take full control of your scene's composition. Specify complex camera moves—such as orbits, crane pans, dolly zooms, or sudden tracking shifts—and get smooth, physically consistent results. It acts like an automated camera operator that respects lighting, depth, and three-dimensional perspective.
Production timelines wait for no one. With a highly optimized inference pipeline and hardware-accelerated kernels, Seedance 1.5 Pro processes video frames up to 10 times faster than previous generation models. Iterate, adjust prompts, and deliver final client exports in a fraction of the time.
Refined on curated, high-definition professional video datasets. The model has undergone extensive Supervised Fine-Tuning to align its outputs with professional cinematographic rules, lighting aesthetics, and detailed motion composition, making it ready for commercial broadcast.
Aligned using Reinforcement Learning from Human Feedback. Utilizing a multi-dimensional reward matrix covering visual quality, motion consistency, and prompt alignment, Seedance 1.5 Pro has been tuned to deliver the exact framing and narrative context that human directors expect.

Tailored solutions for professional video production pipelines.
Directors and storyboard artists can translate written scripts into moving pre-vis shots instantly. Test lighting setups, block out camera movements, and preview action sequences before hiring crew or renting equipment. Seedance 1.5 Pro reduces pre-production time from weeks to hours.
Create engaging, high-conversion commercial ads in multiple languages without expensive voiceover dubbing. The native lip-sync tool allows you to swap speech tracks while maintaining a natural, synchronized look. Download watermark-free, commercially licensed content instantly.
Bypass traditional rendering bottlenecks. Animate characters, create cinematic trailers, or generate background plates with extreme speed. The 10× inference acceleration allows independent creators to output high-volume, premium-quality content to keep up with demanding release schedules.
Produce educational tutorials and corporate training courses with localized speakers. Upload a script in German, Spanish, or Japanese, and watch the virtual instructor's lips align perfectly. Boost student retention and engagement with native-feeling speech.
Seedance 1.5 Pro operates on a specialized dual-branch Spatio-Temporal Diffusion Transformer. Rather than treating video generation as a sequence of flat images, the model represents the output as a continuous 4D spatial-temporal volume. This mathematical representation allows the transformer to learn the fundamental laws of classical mechanics, gravity, fluid dynamics, and light propagation. The visual branch calculates spatial dependencies (relationships between objects in a frame) and temporal dependencies (motion vectors across time) concurrently. Meanwhile, the audio branch is tightly bound to the temporal tokens of the visual transformer. As the visual frames denoise, the corresponding audio waveforms are synthesized in lockstep. This unified cross-modal attention matrix ensures that a cup hitting a table produces the exact impact sound at the precise millisecond of contact, avoiding the disjointed feeling of post-dubbed videos. Furthermore, the post-training alignment framework utilizes a multi-dimensional reward system. Human evaluators rated thousands of video clips across dimensions including structural stability, motion scale, aesthetic appeal, and prompt adherence. This data trained our reward models, leading to a video generator that doesn't just produce beautiful pixels, but understands the art of cinematography.
