THE HOTTEST SKILL
Meet Seedance 2.0 on Happycapy
Generate controllable videos with audio
Seedance 2.0 just landed on Happycapy, and you can access it directly through the generate-video skill. What makes this release worth featuring is not only the visual quality. It is the shift toward controllable, reference driven video creation that feels closer to directing than gambling on a single prompt. Seedance 2.0 is built on a unified multimodal audio video generation architecture that supports text, image, audio, and video inputs in one system, with strong reference and editing capabilities. 
The most noticeable upgrade is controllability. ByteDance frames Seedance 2.0 as a major step forward in instruction following and consistency, with stable, controllable extension and editing that lets regular users command the creation process.  In practice, this means you can be more specific about what should remain stable across shots, what should change, and how the scene should progress. Instead of rewriting prompts and hoping the model keeps the same character, the workflow becomes more like setting constraints and iterating toward a precise take.
Seedance 2.0 also pushes native audio video generation further. The official launch highlights high quality multi shot audio video output up to 15 seconds, with dual channel audio for a more realistic audiovisual experience.  The research paper describing Seedance 2.0 notes that it supports direct audio video generation from 4 to 15 seconds, with native output resolutions of 480p and 720p, and also mentions a Seedance 2.0 Fast variant aimed at low latency scenarios.  If you have ever tried to add sound after the fact, you know how often timing breaks immersion. Here, sound is part of the generation, which makes the output feel more coherent as a single piece of media rather than a silent clip with a track layered on top. 
The multimodal reference story is where Seedance 2.0 becomes especially powerful inside Happycapy. Because the model accepts mixed inputs, you can treat images as visual anchors, videos as motion references, and audio as rhythm or vibe references, then use text to describe the intent and the edits you want.  On Happycapy, the generate video skill turns this into a repeatable workflow. You can start with a short prompt to explore direction, add a reference image to lock the subject, introduce a reference clip to guide camera movement, then refine the instruction until the result matches your mental storyboard. That is the practical difference between a model that is impressive and a model that is usable.
If you are producing short form content, product teasers, motion studies, or narrative clips, Seedance 2.0 on Happycapy is a strong new default. Use generate video when you want fast iteration with more control, richer audiovisual coherence, and a workflow that can be rerun and improved without starting from scratch each time.
