The budget is split across three media types with strict caps: 30 images, 10 video clips, and 10 audio files . These budgets are not interchangeable — you cannot use unused image slots for additional video or audio files.
The Exact Limits at a Glance
| File Type | Maximum Per Generation | Notes |
|---|---|---|
| Images | 30 | Formats: JPEG, PNG, WebP, BMP, TIFF, GIF, HEIC, HEIF. Width/height between 300–6000px, aspect ratio (W/H) between 0.4 and 2.5, file size under 30MB per image |

How Seedance 2.5 Compares to Seedance 2.0
Seedance 2.5 represents a massive increase in creative input capacity. Seedance 2.0 allowed only 9 images, 3 video clips, and 3 audio files — a total of 12 reference files . The new model more than quadruples that ceiling, making it feasible to feed an entire character cast, wardrobe, environment boards, and a full soundtrack into a single prompt.
What Happens with 50 Files in One Prompt?
With 50 reference slots, you no longer need to spend half your prompt describing someone's face or environment from scratch. Instead, you can reference each input directly by number in the text prompt — for example, @Image 1@Video 3@Audio 5. This enables:
- Character consistency: Upload 5–10 images of the same person from different angles.
- Multi-shot storytelling: Combine multiple video clips as motion references for different segments.
- Rich audio design: Use separate audio files for dialogue, ambient sound, and background music.
Important Restrictions to Know
Seedance 2.5 has upstream content restrictions that affect what you can upload as reference files:
- Real human faces (selfies, portraits, celebrities) are not supported for direct upload. Use model-generated assets, preset digital characters, or authorized real-person assets instead
.
- Copyrighted content is also rejected, along with violent and NSFW material
.
- Keeping images under 4K resolution is recommended to avoid processing issues
.
These limits are consistent across all major distribution platforms including JXP, Replicate, LetzAI, and the official ByteDance API .
