Seedance AI Generator

What Makes Seedance 1.5 Pro Superior?

Millisecond-Precision Lip Sync in 8+ Languages

The model supports native lip sync for 8+ languages with dialect-level accuracy. The model understands tonal languages and maps them correctly to mouth shapes.

Supported languages include Mandarin and regional dialects (Shanxi, Sichuan, and others), plus English, Korean, Spanish, and Indonesian. Each language has phoneme-level lip sync accuracy.

Native Joint Audio-Video Generation

Seedance 1.5 Pro uses a dual-branch architecture that creates both simultaneously — locking phonemes to lip shapes and sound effects to visual events at the frame level. This eliminates the uncanny valley of misaligned audio.

Advanced Cinematic Camera Control

The model has advanced camera scheduling capabilities, capable of performing complex camera movements such as long tracking shots and Hitchcock zooms, enhancing the dynamic tension of videos.

Pans, tilts, zooms, tracking shots, handheld motion, overhead angles, and cinematic movements are all supported.
