Seedance 1.5 Pro AI Video Generator

Seedance 1.5 Pro is ByteDance's joint audio-video AI model that generates synchronized video and audio in a single pass. It accurately follows complex prompts to create film-grade content with native sound effects, dialogue, and music—all perfectly timed with the visuals.

Unlike traditional models that add audio post-generation, Seedance 1.5 Pro creates native audio alongside visuals in one unified process. This results in precise lip-sync, natural spatial sound effects, and cinematic camera movements that feel professionally directed.

Seedance 1.5 Pro supports a wide range of languages with accurate lip-sync and motion alignment, including English, Mandarin Chinese, Japanese, Korean, Spanish, Portuguese, Indonesian, and regional dialects like Cantonese and Sichuanese.

Create short dramas with multi-shot storytelling, marketing videos with voiceovers, product demos, multilingual versions of scenes, social media content, and photo animations—all with synchronized dialogue, sound effects, and music.

It supports complex camera movements including close-ups with subtle facial expressions, full-shots with cinematic composition, pans, zooms, and dolly shots. The model excels at maintaining emotional expression and visual continuity across scenes.

For optimal output: keep speaking characters visible (close-ups work best), specify exact dialogue with language/dialect and emotion cues, describe background sounds you want, and include camera movement instructions. Reuse character details across prompts for consistent storytelling.
