On SYNTX.AI, you can access Seedance 2.0 and 2.5 from the same dashboard, along with Kling, Veo, Grok Video and other top video generation models. Navigate to the Video tab and select a model from the dropdown menu on the right-hand side.


Most AI video generation tools cap out at 15 seconds and stitch clips together to go longer, with visible seams at every join. Seedance 2.5 generates a full 30-second scene in a single pass, so a product shot or a short ad plays out start to finish without a cut.
You don't need experience to use AI to create videos. Seedance 2.5 understands simple text prompts (text-to-video) and reads up to 50 references in one generation (image-to-video and video-to-video) to lock in a character, product or brand style.
With SYNTX.AI, you get access to 100+ AI models under one roof, including Seedance 1.0, Seedance 1.5, Seedance 2.0 and Seedance 2.5. Save on separate subscription costs and use all the best AI video generators from a single interface.
