About the model

What is Seedance 2.5?

Seedance 2.5 is ByteDance's newest AI video generation model, built specifically for 30-second storytelling with precise reference control and powerful editing capabilities. It doubles the single-generation ceiling from Seedance 2.0's 15 seconds to a full 30 seconds — removing the need to generate two shorter clips and manually stitch them together.

Where Seedance 2.0 handled one input type at a time, Seedance 2.5 reads up to 50 references at once — text prompts, images, and audio — understood together as one combined creative brief. It also introduces audio-aware pacing: feed it a music track, and the motion and cuts follow the beat automatically.

On UGCad AI, Seedance 2.5 slots directly into the existing ad video generation pipeline alongside every other supported model. You bring the product and the hook; UGCad AI handles the rest — prompt engineering, format optimization, and delivery in 9:16 for Meta, TikTok, and Reels.

Seedance 2.5 capabilities

What makes Seedance 2.5 great for UGC ads

Six capabilities that make Seedance 2.5 the strongest model on UGCad AI for testimonial-length UGC ads, multi-angle product shoots, and audio-synced trend content.

🎬

30-second single pass

Generates a full 30-second ad in one continuous pass — no stitching two clips together, no color-matching between separately generated shots.

🖼️

50 combined references

Reads text, images, and audio together as one instruction set — not one input type at a time like earlier models required.

🔊

Native audio-video generation

Video and audio are generated jointly in one pass, rather than silent video with sound layered on afterward.

🎵

Audio-aware pacing

Feed it a track, and motion and cuts follow the beat automatically — a capability Seedance 2.0 didn't support at all.

🎯

Cross-reference consistency

Multiple product angles stay visually matched — lighting, color, and detail hold steady across a single continuous generation.

✂️

Green-screen & white-model editing

Built-in editing support for professional production workflows, including background compositing and product-only isolation.
