Take one spokesperson portrait and generate lip-synced videos in multiple languages, maintaining the same face, expressions, and production quality across all locales.
Pricing
Using a real human face reference does not change the billing rules for the selected Seedance 2.0 route. The image-to-video example above supports 4–15 seconds per generation.
Estimate costs using the selected Standard or Fast route, output resolution and duration. Reference-to-video requests containing input video use different duration and multiplier rules; do not apply an image-to-video quote directly to them.

FAQ
Does Seedance 2.0 on EvoLink support real human face uploads?
Yes. Seedance 2.0 on EvoLink supports real human face photo uploads as reference inputs without identity verification. Sign up for an EvoLink account and obtain an API key to get started.
Is there an extra cost for real human video generation?
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.
