New: Seedance 2.5
Seedance 2.5 is live inside the first ecommerce ad engine running it.
Seedance 2.5 is ByteDance's newest video-generation model: a 30-second ad rendered as one continuous take, with sound generated in the same pass as the picture. For ecommerce ads, that means no separate stitching pass and no separate audio pass — one generation, a finished video with sound. eComrads runs it live today.
What's new in 2.5
ByteDance announced Seedance 2.5 on June 23, 2026. Here's what changed:
- One continuous 30-second take. No stitching separate clips together — one generation, one take.
- Sound generated in the same pass as the picture. Not added afterward — video and audio are native to the same generation.
- Up to 50 references in a single generation — 30 images, 10 videos, 10 audio clips — to keep a product, a face, or a sound consistent across the shot.
- Region-level editing. Fix or change one part of a frame without regenerating the whole video.
Models are rented. AdDNA is ours.
Generation models learned what an ad looks like; AdDNA learned what makes one convert. Seedance 2.5 is the newest model in the engine — powerful, and eventually available everywhere. AdDNA is the layer underneath every generation that doesn't reset when the next model ships: it decided the shot, the cut, and the hook before Seedance 2.5 ever rendered a frame.
What it means for Amazon ads
For Amazon brand sellers, more creative variants mean more listing and campaign tests without a bigger production budget. Seedance 2.5 generates a 30-second ad in a single take, sound built into the same pass, so a new variant doesn't cost a new shoot. Run it from Claude through the eComrads connector: drop a product photo, ask for the ad. AdDNA is the layer deciding which variant is worth running.
