Seedance V2: Video Editor for Ads and AI Influencers

Multi-Input Generation Transforms Video Models into Editors

Sirio Berati, founder of Enhancor.ai, positions Seedance V2 as the first widely accessible model supporting true multi-input generation: up to two images, two videos, and an audio file in one prompt. This shifts video AI from basic generation to advanced editing. In the first demo, Sirio takes a green-screen video of two characters, inputs replacement character images and a new background image, and prompts Seedance to swap them while preserving exact motions. The result maintains fluid movement, proving natural-language control over complex edits that traditionally required expensive production.

"Cense 2 it's not only a video generator it is a video editor that's how I see it," Sirio explains, comparing it to tools like Nano Banana Pro but for video. Greg Isenberg notes, "The motion control is crazy here," highlighting how the model tags inputs (e.g., for character one) and follows prompts to blend them seamlessly. This capability alone enables production studios to iterate social media demos or landing page videos in 60 seconds, bypassing costly reshoots.

Sirio emphasizes Seedance outperforms Kling 3 in quality for these edits, though Kling suits simpler cinematic prompts. At 720p now, upcoming 1080p will elevate it for professional assets.

Prompt Specificity and Reference Images Drive Quality

Seedance V2 rewards verbose, detailed prompts unlike concise models like Kling 3. Sirio starts with his own drafts, then optimizes using Claude Opus 4.6, which excels at vision-model prompting over GPT variants. For identity preservation, motion matching, and transitions, specificity is key: describe exact actions, lighting, and references.

Reference images are the biggest quality lever. "Everything starts with a very good idea a very good source reference source image," Sirio says. Models mimic the "taste" from strong inputs, like a human assistant. In demos, high-fidelity references ensure outfits match patterns (e.g., boot textures), faces remain undistorted, and elements like bear footprints or eye tracking feel real. Greg, familiar with all major models, admits he couldn't distinguish Sirio's virtual try-on video from real footage.

This duo—detailed prompts plus premium references—yields outputs indistinguishable from live action, critical for business use.

E-Commerce and Product Visualization Workflows

For e-commerce, Seedance V2 excels at virtual try-ons and 3D templating. Sirio filmed himself in -30°C Montreal wearing shorts, input the video plus a winter outfit reference and bear image, prompting a swap. The model preserved his face identically, matched pant patterns precisely, and added coherent bear interaction with eye tracking and footprints—all in 60 seconds.

Commercial angle: Reuse one actor's motion across outfits for consistent brand assets. "If you want to replace... the clothes that they're wearing because you're creating this very cool transition or just because you want a very clean style throughout your e-commerce assets," Sirio notes.

Another demo swaps textures on a generic 3D package render (sourced from stock like Freepik, extended to video) with a branded image. The prompt specifies: replace only the package, apply texture from to , keep motion and background. Output retains logo consistency and yellow backdrop, enabling evergreen templates populated per product. Sirio envisions buying 3D video templates, then AI-texturing them at scale.

Ad Production and Localization at Scale

Ad workflows shine with character replacement, language translation, and A/B testing. Sirio demos a Chinese glasses ad: input original video, English-speaking AI model reference, and prompt to swap the actress, translate speech, preserve wink, hand motion, and camera focus. Output nails the script ("This one's amazing. It's flattering and versatile. Must have."), blur effects, and gestures—perfect for demographic targeting.

"A/B testing at its finest... getting higher conversion rates, just getting cheaper ads because of optimizing," Sirio says. Greg adds, "creating ads and just creating content spec in in like a hundred languages, right?" This isolates variables (language, model) while holding visuals constant, slashing costs versus reshooting.

For AI influencers, Sirio generates lip-sync avatars from Midjourney-style images (Nano Banana Pro referenced). Prompts detail muscle movements and emotional transitions over labels like "happy": e.g., subtle brow lifts, lip curls for realism. Audio input drives sync, enabling faceless accounts, original movies, or converting ads.

Video Extension and Future Model Landscape

Seedance handles extensions unavailable before: append 15 seconds to a 3-second clip or fill gaps between two videos. One demo extends a scene seamlessly, matching final frames and storyline via prompt. Another (teased) bridges clips, recreating middles coherently—vital for ads needing precise lengths or filmmakers bridging shots.

"This has been a pain point for me personally... with ads," Greg says. Sirio agrees, noting prior models like Google Veo 3.1 fell short.

On competition: Seedance is default for editing/generation, but Kling 3 wins cinematic feel, Enhancer V4 talking-head realism. Sirio predicts Adobe's disruption in five years as AI commoditizes creative tools, forcing pivots to workflows.

Enhancor.ai integrates Seedance with any model, streamlining these via a unified interface.

Key Takeaways

• Use multi-input (2 images/videos + audio) with tagged references () for precise edits like character/background swaps in one prompt.
• Craft verbose prompts detailing motions, identities, transitions; optimize drafts with Claude Opus 4.6 for vision tasks.
• Prioritize high-quality source references to convey taste—models mimic them like human assistants.
• For e-commerce: Virtual try-ons preserve actor motion/outfit swaps; texture 3D templates for branded product videos.
• Scale ads via translation + character replacement for A/B tests across languages/demographics, preserving gestures.
• Generate AI influencers by prompting muscle movements/emotions + lip-sync audio, avoiding vague labels.
• Extend videos by appending scenes or filling gaps, matching frames/storylines for ads/filmmaking.
• Default to Seedance V2 for realism/editing; pair with Kling 3 (cinematic), Enhancer V4 (talking heads).
• Build businesses around these: AI influencers, localized ads, templated e-com assets via platforms like Enhancor.

• "Seedance V2... is a video editor that's how I see it. It's almost like nano banana pro whereby the use cases are unlimited." —Sirio on reframing the model.
• "The more detail you give it, the better it does differently from other models." —Sirio on prompting Seedance vs. Kling 3.
• "Everything starts with a very good source reference... they're able to understand your taste and they're able to mimic that reference image." —Sirio on references as the quality lever.
• "It looks like me. There's no distortion in the face, which is crazy." —Sirio reacting to his own undistorted try-on demo.
• "A/B testing at its finest. Yeah. And getting higher conversion rates, just getting cheaper ads because of optimizing." —Sirio on ad localization value.
