Seedance 2.5

What is Seedance 2.5?

Seedance 2.5 is ByteDance's advanced AI video generation model that creates complete 30-second video clips in a single generation pass. Unlike most AI video tools that cap at 4–15 seconds or require stitching multiple clips, Seedance 2.5 generates full narrative sequences from text prompts, image references, audio cues, or any combination of multimodal inputs — eliminating fragmentation and maintaining visual consistency throughout the entire clip.

Who It's For

Seedance 2.5 is built for creators, marketers, agencies, and e-commerce teams who need production-ready video drafts faster than traditional shoots allow. Content creators can develop complete story beats for social media without stitching loops. Marketers can test product videos in branded environments before committing to full shoots. Agencies can present moving 30-second concepts to clients and iterate with targeted edits. E-commerce teams can generate master clips and swap products frame-by-frame for catalog-scale production.

Key Features & Capabilities

• 30-second native output: Generate complete scenes in one pass — more than double the clip length of competing models (vs. 8–15 seconds for Veo 3.1 and Kling 3.0)
• Up to 50 multimodal reference inputs: Feed images, audio files, video samples, character sheets, product photos, color palettes, and brand assets together — roughly 2× the 12-input limit of Seedance 2.0
• Local re-draw editing: Change specific elements (products, backgrounds, subjects) without regenerating the entire clip, preserving camera path, motion, and composition — ideal for per-SKU variants and client revisions
• Native 1080P and 10-bit color: Source resolution output (not upscaled) with 10-bit color depth for professional grading workflows
• High-quality video extension: Extend clips while maintaining visual consistency and style from the original generation
• 20% improved prompt adherence: Better first-generation accuracy reduces iteration cycles

Differentiators

Seedance 2.5 builds on Seedance 2.0, which ranks #1 on the Artificial Analysis Video Arena (Elo 1,219) for text-to-video and image-to-video generation. The model addresses three critical production limits: clip duration, reference volume, and post-generation editing. Where other tools force users to fragment ideas across multiple short clips or discard near-perfect results over single-element mismatches, Seedance 2.5 delivers complete, editable scenes that match complex creative briefs on the first pass.

Availability

Seedance 2.5 was announced June 23, 2026 at ByteDance's Volcano Engine FORCE conference and is now available on XMK with credit-based pricing. The platform supports direct online generation with full prompt control, reference uploads, and resolution/duration settings displayed before submission.
