Seedance 1.5 Pro
Seedance 1.5 Pro is ByteDance's advanced image-to-video model with native audio-visual synchronization, enabling cinematic 1080p clips up to 12 seconds with sound and dialogue.
Overview
What is Seedance 1.5 Pro
Seedance 1.5 Pro is ByteDance's image-to-video AI model, released in December 2025, that generates up to 12-second cinematic videos with synchronized audio from a single image and prompt. It supports resolutions up to 1080p and integrates sound effects and multilingual dialogue in one generation pass.
Running it privately on Venice
On Venice, Seedance 1.5 Pro runs under an anonymized privacy tier — your prompts are never stored or used for training. This means you can generate uncensored, high-resolution audio-video content without leaving a trace. The model's native audio-visual sync and cinematic control are fully accessible, making it ideal for creators who value both privacy and professional output quality.
Assessment
Strengths and limitations
- Native audio-visual synchronization: generates video and sound (dialogue, effects) in one pass with precise lip-sync across multiple languages and dialects.
- Strong prompt adherence, especially for camera movements like dolly, pan, and follow shots.
- Supports Chinese-friendly prompting, beneficial for e-commerce and short-form content teams.
- Cinematic quality with dynamic camera control and enhanced narrative coherence.
- Available on Venice with zero retention: prompts are anonymized and not stored.
- Max resolution capped at 1080p: lags behind 4K models like Kling V3 or Veo 3.1.
- Clip length limited to 12 seconds: shorter than Sora 2’s 120-second capability.
- Detail instability in complex scenes, particularly with hands and fast motion.
- Proprietary model: no open weights, so no self-hosting or fine-tuning options.
Samples
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera
