Core Highlights of Seedance 1.5 Pro

Native Audio-Video Generation

Generate synchronized video and audio in a single pass. Create ambient sounds that match the scene, character voices that follow the emotion, and background music that fits the mood, all coordinated with what happens on screen.

Multilingual and Dialect Accent Support

Supports speech generation in multiple languages and regional accents, including English, Chinese, Japanese, Korean, Spanish, Indonesian, Mandarin, Shaanxi dialect, and Sichuan dialect for more realistic local speech.

Improved Lip-Sync

Keeps speech and mouth movements aligned across different languages and dialects. It maps spoken sounds to matching lip shapes so generated characters speak with more natural timing and expression.

Film-Grade Camera Motion Control

Interprets camera-motion descriptions precisely, including panning, tilting, zooming, tracking, side-to-side movement, and orbit-style motion. Use camera movement to evoke emotions and create professional, cinematic visuals.

Stronger Character Consistency & Narrative Coherence

Preserves key features of each character across different scenes and shots, including facial details, body shape, and clothing. Extends narrative content while keeping emotions, expressions, and actions consistent.

Developer Reviews from Teams Using Our Seedance 1.5 Pro API

★★★★★
"The API was pretty easy to get running. I used it for a small text-to-video demo, and the parameters were clear enough to test different durations and aspect ratios quickly."
Daniel Park Backend Developer
★★★★★
"What I like most is the audio-video sync. For short dialogue clips, the mouth movement and voice timing looked much better than the separate audio workflow we used before."
Mia Chen AI Product Manager
★★★★☆
"Image-to-video worked well for our product mockups. It still takes some prompt tuning, but having first-frame reference support made the results easier to control."
Arjun Patel Full-Stack Engineer
★★★★☆
"The async flow is what you'd expect for video generation. Submit a job, poll the result, then use the output URL. Nothing fancy, but it fits into our backend without much trouble."
Sofia Ramirez Platform Engineer
★★★★☆
"The 1080p outputs are useful, but generation time can vary depending on the prompt and settings. For production, we had to design our UI around waiting states."
Ethan Brooks Frontend Developer
★★★★☆
"We tested it for multilingual character clips. Some outputs needed retries, but the language and lip-sync support gave us enough confidence to keep experimenting."
