Does this workflow generate audio (music or dialogue) along with the video?

No. This graph outputs video only via SaveVideo. To add music, VO, or dialogue, mux an audio file afterward in your editor or extend the workflow with audio/muxing nodes.

What resolution and aspect ratios are supported?

Any common aspect ratio works. For 1080p deliverables, use 1920x1080 (landscape), 1080x1920 (vertical), or 1080x1080 (square). Keep the long edge at 1080 and match your source image’s aspect ratio to minimize cropping.

How long can the clip be, and what are performance considerations?

Up to ~30 seconds is practical. Longer clips and higher FPS increase VRAM and render time. For mid-range GPUs, start with 16–24 FPS and moderate motion strength; if VRAM is limited, consider shorter durations or 720p tests first.

Can I automate this via the ComfyUI API?

Yes. Serialize the workflow JSON and POST it to ComfyUI’s /prompt endpoint. Provide your image as a file path (server-side) or base64. Set duration, FPS, resolution, and seed in the ByteDance2ReferenceNodeV2 before triggering the run.

Seedance2.5 1080P: Image to Video

This ComfyUI workflow turns a single still image into a polished 1080p video clip using Seedance 2.5 via the ByteDance2ReferenceNodeV2. The graph is intentionally simple and reliable: LoadImage brings your source frame into the pipeline, ByteDance2ReferenceNodeV2 synthesizes motion-conditioned frames from that reference, and SaveVideo encodes the output sequence to a playable MP4 at your chosen frame rate and aspect ratio. You control duration (up to ~30 seconds), FPS, motion strength, and seeding for reproducible results.

Technically, the ByteDance2ReferenceNodeV2 uses the input image as a visual prior, generating a temporally coherent frame sequence that preserves identity and structure while introducing camera-like moves (e.g., gentle pans, zooms, and parallax) and scene dynamics. Because resolution and aspect ratio are configurable, you can produce 1920x1080 landscape, 1080x1920 vertical, or square clips while maintaining 1080 on the long edge. SaveVideo then assembles frames at the specified FPS. Note: this minimal graph outputs video only; to add music, dialogue, or foley, mux audio afterward or extend the workflow with audio nodes/external tools.

Use this workflow from code

Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.

Fetching workflow JSON…

Run it from Python or TypeScript with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.

# Install (beta)
pip install comfy-sdk        # Python
npm i @comfyorg/sdk          # TypeScript

# Run this workflow (Python)
from comfy_sdk import Comfy

client = Comfy(api_key="comfyui-...")
wf = client.workflows.from_file("workflow_api.json")
job = client.run(wf)
for output in job.get_outputs("<output-node-id>"):
    output.to_file(output.name)

The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API). API access requires a Comfy Cloud plan with an API key. SDK docs · Get an API key
