What's new

What Seedance 2.5 can do, as ByteDance describes it.

These are the model's capabilities from ByteDance's launch post of July 31, 2026. On Shhots AI the model sits inside ad workflows, so you use it through the AI UGC ad and cinematic ad flows below rather than through raw model controls.

Up to 30 seconds per generation

ByteDance's launch post says Seedance 2.5 renders up to 30 seconds in one pass. That is long enough for a hook, a demo and a close in a single clip.

Extension beyond 30 seconds

The model supports multiple rounds of extension, so a clip can continue past its first generation instead of being rebuilt from scratch.

Audio and video generated together

Speech, sound effects and music come from the same model pass as the picture, so sound and image stay in sync. ByteDance also lists control over background music.

Multi-shot scenes with camera moves

Seedance 2.5 handles several logically connected shots and camera transitions inside one generation, which suits ads that cut between a face, a product and a setting.

Up to 50 reference inputs

Up to 30 images, 10 video clips and 10 audio clips can guide one generation. More references give tighter control over what appears on screen and how it sounds.

Edit a single moment

ByteDance lists timestamp-level editing, green screen background replacement, camera perspective edits and reference-based edits, so one moment can change without regenerating the whole clip.

On Shhots AI

Seedance 2.5 for AI UGC ads and cinematic ads.

Seedance 2.5 is available for the two ad types that matter most in paid social. Both start from one product photo.

AI UGC ads

A creator-style ad from one product photo: a hook, a demo and a close, with voiceover and captions. It is the format paid social buyers use to test angles fast.

See the AI UGC ads generator

Cinematic ads

A studio-look product video with motion, lighting and camera work, for hero placements, landing pages and brand moments.

Both clips are sample 30-second ads made on Shhots AI. Credit cost depends on the ad length you choose, and the app shows it before you generate.

Best for

Six ways to use Seedance 2.5 for ads.

30-second Meta and TikTok ads

A single clip long enough to carry a hook, a product demo and a closing offer, in the vertical format paid social favors.

UGC testimonial ads

A creator-style video talking to camera about your product, for paid social, product pages and marketplace listings.

Cinematic product films

Studio-look product video with considered lighting and camera work, for a launch, a landing page or YouTube.

Hook testing

Keep the product and the offer, change the opening seconds, and compare which version holds attention.

Shopify and dropshipping videos

Turn a product photo into a finished video ad without a shoot, a creator to brief or an editor on retainer.

Sound-on placements

Reels, Shorts and TikTok play with sound. Audio generated with the picture means speech and music arrive in the same pass.
