No workflow setup required · Fully customizable in AI-Flow
What This App Does
Seedance 1.5 Pro is a joint audio–video generation model that creates cohesive, story-ready clips in a single pass. It produces visuals and sound together, delivering frame-accurate lip-sync, ambient effects that match on-screen action, and background music aligned to mood and pacing.
Built for creative and production workflows, the model understands complex camera direction (pan, tilt, dolly, orbit, zoom), maintains character and wardrobe consistency across shots, and preserves background stability to avoid warping artifacts. It supports multilingual dialogue with natural phoneme-to-mouth alignment, including English, Mandarin, Japanese, Korean, Spanish, Portuguese, Indonesian, and dialects like Cantonese and Sichuanese.
Use it for text-to-video or image-to-video. Provide a prompt describing scene, movement, and audio cues; optionally upload a start image and a last-frame image to guide beginning and ending frames. Configure aspect ratio, duration, frame rate, camera lock, audio generation, and an optional seed for reproducibility. Outputs are delivered as video files (up to 1080p) suitable for social content, ads, trailers, explainers, and narrative shorts.
Tips for best results
Write specific, visual prompts that include setting, lighting, subject actions, and desired camera motion.
If you need audio, explicitly describe dialogue (with language), sound effects, or music style and mood.
For image-to-video, start with clear, well-lit images where key subjects (faces, products) are unobstructed.
Keep character details consistent across prompts when producing multi-shot sequences.
Use camera_fixed when you want minimal camera movement (e.g., talking heads, product close-ups).

Frequently Asked Questions
What makes Seedance 1.5 Pro different from other video models?
It generates audio and video simultaneously, not sequentially. This native coupling delivers precise lip-sync and sound effects that align perfectly with on-screen events, reducing post-sync work.
Can it generate both text-to-video and image-to-video?
Yes. Provide a text prompt for text-to-video. For image-to-video, upload a starting image; optionally add a last_frame_image to guide the ending frame for smoother story beats.
How do I get synchronized dialogue or music?
Enable generate_audio and specify the audio details in your prompt—include language, voice tone, exact lines of dialogue, and any SFX or music style so the model can align visuals and sound.
Which languages are supported for lip-sync?
The model supports multiple languages and dialects, including English, Mandarin Chinese, Japanese, Korean, Spanish, Portuguese, Indonesian, and Chinese dialects such as Cantonese and Sichuanese.
What parameters can I control?
You can set prompt, duration (seconds), aspect_ratio, fps, camera_fixed, generate_audio, and an optional seed. For image workflows, you can also provide image and last_frame_image.
What output quality should I expect?
The model produces up to 1080p video with smooth motion and stable backgrounds. Quality depends on prompt clarity, source image quality (if used), and chosen duration and aspect ratio.
When should I use camera_fixed?
Use camera_fixed for scenes where you want minimal camera movement, such as interviews, product close-ups, or static compositions. Disable it to allow dynamic pans, tilts, or tracking shots.
How does last_frame_image work?
When using image-to-video, you may optionally supply a last_frame_image to guide the visual target for the final frame. This helps create clearer start and end states in short sequences.
Can I reproduce a result exactly?
Set a seed to increase reproducibility. Due to the stochastic nature of diffusion models, minor variations can still occur across runs.
What are typical durations and aspect ratios?
Common settings include 2–12 seconds and aspect ratios like 16:9, 1:1, 4:3, 3:4, 9:16, 21:9, and 9:21. Choose based on your platform or creative needs.
How much does it cost to run?
Pricing may vary by platform. As a guideline, expect higher cost per second when generate_audio is enabled than without audio. Check your deployment environment for the current rate.
