In this episode I sit down with my friend Sirio, one of the most creative AI minds I know, to break down Seedance V2. Sirio walks us through the exact use cases, prompts, and tactics he’s using to build on top of this model inside his platform Enhancor, covering multi-input generation, virtual try-ons, ad translation, AI influencers with lip sync, video extension, and 3D product template replacement. I wanted this to go beyond the "look how cool this is" tutorials and focus on how creators and founders can actually build businesses, run ads, and produce creative assets with it. By the end, you’ll have a practical playbook for Seedance V2 and a clear view of where it fits alongside other models like Kling 3, Veo, and fine-tuned options.

Key Points
* Seedance V2 is the first widely available video model to support true multi-input generation — up to two images, two videos, and an audio file combined in a single prompt.
* Treat Seedance V2 as a video editor, not just a generator: character swap, background swap, text preservation, ad translation, and template population all work from natural-language prompts.
* Seedance rewards highly specific prompts; I pair my own draft with Claude Opus 4.6 to optimize prompts for vision models.
* Strong source reference images remain the single biggest quality lever — the model mimics taste from what you feed it.
* For AI influencers and lip sync, describe muscle movements and emotional transitions rather than simply labeling an emotion like "sad" or "happy."
* Seedance V2 is the current default for editing and generating video, yet other models (Kling 3 for cinematic feel, Enhancer V4 for talking-head realism) still win on specific use cases.
Numbered Section Summaries
1. The Multi-Input Breakthrough Seedance V2 launched today and accepts multiple inputs at once — up to two images, two videos, and audio. That lets Sirio and me do things earlier models struggled with: replace two characters and a background in a green-screen shot from a single prompt, with motion preserved. This is the capability that turns a generator into an editor.
2. Prompting and Source References Seedance rewards specificity. Short prompts work on models like Kling 3, while Seedance performs better the more detail you give it — especially for character identity, motion preservation, and transitions. Sirio drafts prompts himself and optimizes with Claude Opus 4.6. The other half of the equation is source references: a great reference image lets the model understand taste and vision, the same way a human assistant would.
3. Virtual Try-On and E-Commerce Applications Sirio shot himself in Montreal in minus 30-degree weather wearing shorts, then used Seedance V2 to swap his outfit into a full winter fit and add a bear walking through the frame. His face stayed identical, the boots and pant pattern matched the reference exactly, and the model tracked the bear with its eyes. The commercial angle: swap e-commerce model outfits while preserving identity and motion for consistent brand assets.
4. Ad Translation and A/B Testing at Scale One demo replaces a Chinese-speaking model in a glasses ad with a different AI-generated model speaking English — same wink, same hand motion, same camera focus. The use case is obvious: A/B test creative across languages and demographics while holding motion and framing constant to isolate the variable. Cheaper ads, higher conversion, continuous optimization.
