Seedance 2.5
Seedance 2.5 is ByteDance's next-generation AI video model, generating up to 30 seconds of cinematic, audio-synced video from a single image input with precise reference control.
Overview
What is Seedance 2.5
Seedance 2.5 is ByteDance's advanced image-to-video model that generates up to 30 seconds of high-quality, audio-synced video in one pass from a single image. Released in July 2026, it supports multi-modal references, region-level editing, and native audio generation, enabling production-ready storytelling without clip stitching.
Running it privately on Venice
On Venice, Seedance 2.5 runs under an anonymized privacy tier — your prompts and reference materials are not stored or profiled. This means creators can generate cinematic, photorealistic video content with full audio integration while retaining sovereignty over their inputs. The model’s long-duration, high-resolution capabilities are accessible without surveillance or data retention.
Assessment
Strengths and limitations
- Generates full 30-second videos natively in one pass — no stitching, no consistency drift.
- Supports up to 50 multimodal reference inputs (images, video clips, audio) for precise creative control.
- Produces cinematic, photorealistic content with synchronized audio in the same latent space.
- Enables region-level natural language editing: modify backgrounds, swap objects, adjust pacing without regenerating.
- Ideal for long-form social content, brand storytelling, and 3D-to-video pipelines.
- Proprietary and closed: no open weights, so self-hosting or fine-tuning is not possible.
- No support for 4K resolution: maximum output is 1080p.
- Higher cost per second compared to prior versions and open-weight alternatives.
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
