Seedance 2.5 AI Video Generator
Create native 30-second single-segment AI UGC video ads with richer story rhythm, up to 50 joined reference assets, and frame-accurate editing — no stitching, no quality loss between clips.
What Is Seedance 2.5?
Seedance 2.5 is ByteDance's next-generation AI video model, built for longer native scenes, richer multi-asset understanding, and more controllable refinement. Unlike most AI video generators, which cap a single generation at 5–10 seconds and require stitching multiple clips into one ad, Seedance 2.5 generates a complete 30-second video in a single continuous pass — preserving camera movement, lighting, and subject consistency throughout.
It accepts up to 50 joined reference inputs across images, video, and audio, so the model can understand multiple characters, products, scenes, motion references, sound cues, and brand details at once. Combined with region-level editing — the ability to adjust a specific part of a generated video without regenerating the whole clip — Seedance 2.5 is built for production teams that need both scale and creative control.
Tagshop AI will offer Seedance 2.5 as a selectable AI video generator model, so you can paste a product URL and generate a full 30-second AI UGC ad with consistent characters and product placement throughout — no manual clip stitching required.

Three Ways to Generate with Seedance 2.5
Multi-reference, image-to-video, or text-to-video — Seedance 2.5 accepts all three
Text to Video
Describe your scene, subject, camera movement, and narrative rhythm. Seedance 2.5 generates a full continuous 30-second ad from your description — no stitching required.
Image to Video
Upload a product image or reference photo. Seedance 2.5 animates it with natural motion into a continuous scene with consistent character and product placement.
Multi-Reference Generation
Upload up to 50 combined assets — images, videos, and audio. Seedance 2.5 uses all references at once to produce a 30-second ad where characters, products, and brand identity stay consistent throughout.
The Seedance 2.5 Prompt Framework
Six elements to include in every prompt — the more detail, the higher the output quality across your 30-second ad
Prompt: Describe the main subject, what they do, wear, hold, and how they move — e.g. 'A woman in her 30s holding a skincare bottle, turning to face camera, soft confident smile, walking toward product display'
Prompt: Add camera direction for the full 30-second arc: close-up, wide angle, tracking shot, static, dolly-in — e.g. 'opens on close-up of product, dolls back to reveal presenter, wide shot of full scene by 20 seconds'
Prompt: Specify visual aesthetic: cinematic, soft studio, golden hour, natural daylight — e.g. 'cinematic grade, golden hour lighting, warm colour palette, consistent throughout'
Prompt: Add scene setting, atmosphere, and narrative pacing: 'minimal studio, white background, transitions from product close-up to lifestyle scene at 15 seconds'
Prompt: Use up to 50 combined image, video, and audio references to anchor visual style — 'same character as reference image, same product as reference photo, audio reference for ambient sound'
Prompt: Add region-level edit commands after generation: 'change background to outdoor garden scene', 'update product label to new version', 'adjust character expression at 20-second mark'
Prompt: "A skincare serum on white marble, camera pans close to reveal label, presenter enters at 10 seconds and holds product to camera, wide lifestyle scene at 25 seconds — 30s, 9:16, 4K"
Prompt: "A woman speaking to camera about a beauty product, warm studio setting, consistent character throughout 30 seconds, product visible at 5 and 25 seconds — 30s single segment, 9:16"
