Image to Draft to 1080p

Template: Image to Draft to 1080p, in the ComfyUI template browser under BytePlus
Workflow file: Image to Draft to 1080p.json
BytePlus nodes: Seedance 2.5 Reference to Video, Seedance 2.5 Draft to Final Video
Keys needed: ModelArk API key
Also uses: Load Image, MarkdownNote, Save Video (built into ComfyUI)

What it makes

A reviewed draft becomes a 1080p video. Your image guides the subject and style. Seedance 2.5 Draft creates a 480p preview, then Draft to Final keeps its scene and motion in the final render.

The workflow

Reference image connected to Seedance 2.5 Draft and Save Video, with Draft to Final and the final Save Video bypassed — Review the draft before enabling the two purple final nodes.

Load Image supplies your character or style reference.
Seedance 2.5 Reference to Video uses Seedance 2.5 Draft, 480p, 16:9 and 5 seconds.
Save Video saves and displays the draft for review.
Draft to Final Video receives draft_task_id and renders at 1080p. The final stage starts bypassed.
A second Save Video saves and displays the final.

Run it

Set your ModelArk API key in Settings → BytePlus (API keys).
Open Image to Draft to 1080p, upload your image and edit the prompt.
Run and review the draft in Save Video.
Select both purple final nodes and press Ctrl+B to enable them. Run again with the draft inputs unchanged.
Keep the draft seed control on fixed to reuse the cached draft. To revise the shot, bypass both final nodes again before changing the image, prompt or seed.

Settings worth changing

Prompt: refer to your subject as Image 1 and describe motion, camera and sound.
Ratio and duration: set these in the draft; the final inherits them.
Seed: keep fixed during review and final generation. Change the seed deliberately for a new draft.
Model: keep Seedance 2.5 Draft for a 1080p final. Premium drafts render at 4k.
Audio: the final inherits the draft’s audio setting.

Example result

This example uses ComfyUI’s bundled illustrated character image. The draft is 854 × 480 and the final is 1920 × 1080. Both are 24 fps, about five seconds long, with audio.

ComfyUI displays the illustrated character in both the draft and final Save Video nodes — The same reviewed draft renders successfully at 1080p.

Time and cost

Draft and final are separate billed tasks. The final nodes start bypassed, so the first run requests only the draft. An unchanged draft with a fixed seed is reused from ComfyUI’s cache. Restarting ComfyUI clears that cache; use a saved draft task ID in a separate Draft to Final workflow to render an existing draft without requesting another. Draft tasks can be rendered for seven days.
