If you need to generate realistic videos of real people using AI, Seedance 2.0 is now one of the strongest options available — and it is fully accessible through GPTImage2's API.
Seedance 2.0 real human video generation is available on GPTImage2, accessible through the same unified API used for all video models on the platform.
This guide covers what Seedance 2.0's real human video capabilities actually are, how to use them via API, and how they compare to alternatives like OmniHuman 1.5, HeyGen, and Kling 3.0.
What Is Seedance 2.0 Real Human Video?
Seedance 2.0's real human video capability means the model can accept real human face photographs as reference inputs and generate video output featuring those people with high fidelity. This is not a separate model or mode — it is the core Seedance 2.0 model with content moderation restrictions lifted.
When real human video is enabled, Seedance 2.0 can:
- Preserve facial features from a reference photo throughout the video, including during head turns and lighting changes
- Generate natural micro-expressions with cinematic quality
- Produce full-body motion — dance choreography, athletics, gestures — one of the stronger options among current AI video models
- Maintain character consistency across multi-scene sequences
- Generate multi-language lip-synced dialogue from reference photos with native audio
- Accept up to 9 reference images tagged in prompts for character, wardrobe, and set persistence

What Makes Seedance 2.0 Different for Human Video
vs OmniHuman 1.5
OmniHuman 1.5 (also from ByteDance) is focused on audio-driven human animation — animating a single portrait with audio input. Seedance 2.0 is a full cinematic video generation model that happens to support real human faces.
| Capability | Seedance 2.0 | OmniHuman 1.5 |
|---|---|---|
| Primary use case | Full scene video generation | Audio-driven portrait animation |
| Scene control | Full (camera, lighting, environment) | Limited (portrait focus) |
| Multi-character scenes | Yes (up to 9 references) | No |
| Audio generation | Native (generates audio) | Requires audio input |
| Max duration | 15 seconds | Varies |
| Best for | Ads, storytelling, creative video | Talking head, lip-sync |
Use OmniHuman when you need a talking head from audio. Use Seedance 2.0 when you need a real person in a full cinematic scene.
vs HeyGen
HeyGen positions itself as the "only platform where Seedance 2.0 works with real human faces" through its identity verification layer. GPTImage2 also supports real human face uploads through its own verification process.
| Capability | Seedance 2.0 on GPTImage2 | HeyGen + Seedance |
|---|---|---|
| Model source | Available on GPTImage2 | Available through HeyGen |
| Real face upload | Supported (after verification) | Requires HeyGen verification |
| API access | Direct REST API | HeyGen platform only |
| Per-second billing | Yes | HeyGen subscription plans |
| Full Seedance 2.0 features | All variants (T2V, I2V, V2V, reference) | Limited to HeyGen workflows |
| Multi-model routing | Yes (switch to Kling, Sora, etc.) | Seedance only |
vs Kling 3.0 and Sora 2
Neither Kling 3.0 nor Sora 2 offers the same level of real human video support as Seedance 2.0.
| Feature | Seedance 2.0 | Kling 3.0 | Sora 2 |
|---|---|---|---|
| Real human face reference | Full support | Limited | Limited |
| Human motion quality | Best (dance, athletics) | Good | Good |
| Multi-language lip-sync | Native | No | Limited |
| Reference count | Up to 9 images + 3 videos + 3 audio | 1 image | 1 image |
Use Cases
1. Face-Led Advertising
Upload a model or spokesperson's photo and generate product ad videos with natural expressions and body language. Seedance 2.0's multi-reference system lets you control wardrobe, background, and camera angle separately.
2. Spokesperson & Talking Head Content
Generate spokesperson videos with lip-synced dialogue in multiple languages from a single portrait photo. Combine with audio references for precise timing and rhythm control.
3. Influencer-Style Creative
Create social-first video content featuring real people without a full production shoot. Ideal for testing creative variants at scale before committing to live production.
4. E-commerce Product + Model Videos
Combine product images with model portrait references to generate product demo videos where a real person interacts with the product — at a fraction of traditional production cost.
5. Localized Marketing at Scale
Take one spokesperson portrait and generate lip-synced videos in multiple languages, maintaining the same face, expressions, and production quality across all locales.

Does Seedance 2.0 on GPTImage2 support real human face uploads?
Yes. Seedance 2.0 on GPTImage2 supports real human face photo uploads as reference inputs. Sign up for an GPTImage2 account and complete verification to get started.
Is there an extra cost for real human video generation?
No. Real human video uses the same per-second pricing as all other Seedance 2.0 generation modes on GPTImage2.
How does Seedance 2.0 real human video compare to deepfake tools?
Seedance 2.0 is a generative AI video model, not a face-swap or deepfake tool. It generates entirely new video from text prompts and reference images, rather than replacing faces in existing footage. All outputs include invisible watermarks for provenance tracking.
Can I generate videos of celebrities or other people without consent?
Content policies apply. Seedance 2.0 blocks celebrity and copyrighted character likenesses. You should only use photos of individuals who have given consent for AI video generation.
What is the best input format for portrait photos?
High-resolution, well-lit portrait photos with a clear face work best. Front-facing or slight-angle photos produce the most consistent results. The model accepts JPEG and PNG formats up to 30MB per image.
How long can real human videos be?
Seedance 2.0 supports 4-15 seconds per generation. For longer content, you can generate multiple clips and use the multi-shot reference system to maintain character consistency across segments.
