description: >
  Animate a single still image into a 4-30 second 720p cinematic clip with
  optional synchronized native audio using ByteDance Seedance 2.5 Image to
  Video on RunComfy. Documents the four-field schema (prompt, image,
  duration, generate_audio), the $0.35/s pricing, the fact that output
  aspect ratio follows the input image, and when to route to the Seedance
  2.5 480p, text-to-video, reference-to-video or first-last-frame pages
  instead. Calls `runcomfy run bytedance/seedance-2.5/image-to-video/720p`
  through the local RunComfy CLI. Triggers on "seedance 2.5 image to
  video", "seedance image to video", "seedance i2v", "animate this image
  with seedance", "bytedance image to video", or any explicit ask to turn
  a still into video with Seedance 2.5.

# Seedance 2.5 Image to Video

[runcomfy.com](https://www.runcomfy.com/?utm_source=skills.sh&utm_medium=skill&utm_campaign=seedance-2-5-image-to-video&utm_content=home) · [Seedance 2.5 Image to Video](https://www.runcomfy.com/models/bytedance/seedance-2.5/image-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=seedance-2-5-image-to-video&utm_content=bytedance-seedance-2.5-image-to-video) · [GitHub](https://github.com/genmedia-labs/skills/tree/main/seedance-2-5-image-to-video)

ByteDance **Seedance 2.5 Image to Video (720p)** turns **one still image** into a 4–30 second cinematic clip with optional synchronized native audio, hosted on the **RunComfy Model API**. The output aspect ratio follows your input image.

```bash
npx skills add genmedia-labs/skills --skill seedance-2-5-image-to-video -g
```

## When to pick this model (vs siblings)

This page is the **single-image path**. It has no aspect-ratio control and no multi-reference input — you give it one image and a motion prompt, and it animates that frame. That narrowness is the point: nothing competes with the source still for identity, wardrobe, or composition.

| You want | Use |
|---|---|
| Animate one still, keep subject and framing intact | **Seedance 2.5 Image to Video 720p** (this skill) |
| Native speech / SFX / music generated in the same pass | **Seedance 2.5 Image to Video 720p** (`generate_audio: true`) |
| A single continuous shot up to 30 seconds | **Seedance 2.5 Image to Video 720p** |
| Cheaper, faster drafts before the final render ($0.17/s) | [Seedance 2.5 Image-to-Video 480p](https://www.runcomfy.com/models/bytedance/seedance-2.5/image-to-video/480p?utm_source=skills.sh&utm_medium=skill&utm_campaign=seedance-2-5-image-to-video&utm_content=bytedance-seedance-2.5-image-to-video-480p) |
| Multiple image / video / audio references in one shot, plus an aspect-ratio control | [Seedance 2.5 Reference-to-Video](https://www.runcomfy.com/models/bytedance/seedance-2.5/reference-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=seedance-2-5-image-to-video&utm_content=bytedance-seedance-2.5-reference-to-video) |
| No image at all — generate from a prompt only | [Seedance 2.5 Text-to-Video](https://www.runcomfy.com/models/bytedance/seedance-2.5/text-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=seedance-2-5-image-to-video&utm_content=bytedance-seedance-2.5-text-to-video) |
