Seedance 2.5 Draft to Final: From 480p Tests to 1080p Video
Compare ideas with 480p Drafts before creating a 1080p Final. Learn what to check, how to plan your budget, and when a direct 1080p generation makes more sense.
APIXO Team
Need one finished video, but several ideas to choose from? The Seedance 2.5 Draft-to-Final workflow lets you review 480p candidates before generating a selected result in 1080p. It gives each round a clear decision: is the idea worth taking to a Final?
This guide covers how to plan a Draft, review the full clip, and budget for a Final. Start in the Seedance 2.5 Playground, or use the API guide to integrate the workflow into your application.
How Seedance 2.5 Draft to Final works
Generate a 480p Draft to test a creative direction.
Review the clip and choose a candidate that meets your brief.
Use the selected Draft to request a 1080p Final, then review that output before publishing it.
A Draft is a generated, billable video. “Draft” does not mean a free preview or an unsent project. Set a spending limit for the whole round, including the Final and any retries.
Step 1: Write a brief you can evaluate
Decide where the video will be used and what must stay consistent. For a product reveal, prioritize product shape, camera movement, and the order of the reveal. For dialogue, add speech timing and intelligibility.
Here is an illustrative brief you can adapt:
Placement: vertical social teaser
Subject: one unbranded ceramic cup on a table
Action: the camera moves closer as steam rises
Must keep: cup shape, handle, and calm lighting
Reject if: the handle changes shape or steam hides the cup
This brief has not been tested with a paid generation. Treat it as a planning example, then refine it against your own results.
Keep a simple record of the prompt, reference files, duration, aspect ratio, and sound setting for each candidate. Change one major instruction at a time when possible: that makes it easier to understand which change improved the clip.
Step 2: Generate and review 480p Drafts
Open the Playground, enter your brief, enable Draft, and check the resolution and price estimate before submitting. Available controls and the quote shown to your account are the practical checks to make each time.
Watch the entire clip at least once before comparing details. Use this checklist:
Subject continuity: Does the main person or object remain recognizable from beginning to end?
Motion and contact: Do hands, feet, props, and camera movements behave coherently?
Framing and timing: Is the important action visible, and does the ending leave the space you need?
Text and fine detail: Are lettering, logos, faces, or small product features usable for the intended placement?
Audio: If enabled, is speech understandable and appropriately timed with the picture?
A 480p Draft can help you judge direction and timing. It cannot establish how every fine detail will look in a 1080p Final. Save each useful Draft’s task ID and a short note explaining why you selected it.
Choose the candidate that best meets the brief. A visually striking clip can still be the wrong choice if it changes the product or misses the required action.
Step 3: Create and check the 1080p Final
For a successful Draft, use the Generate 1080p Final action where available in your results. The developer route passes the successful Draft’s APIXO task ID as draft_task_id; see the Draft-to-Final API instructions for the request format.
The Final inherits the Draft’s prompt, references, mode, duration, aspect ratio, and sound choice. Do not resend or change those fields in the API Final request. If you need a different action or framing, make a revised Draft first.
A successful Draft is eligible for Final generation for seven days and can be reused for multiple independent Finals. Each Final is a separate charged generation.
Review the Final again before using it. Inherited settings do not guarantee identical frames. Check the details that matter at delivery size: product edges, faces, lettering, dialogue, audio synchronization, and the last frame.
Cost example: five Drafts and one Final
For a hypothetical text-to-video exercise, suppose you compare five four-second candidates, use no video references, and generate one Final.
The APIXO pricing table, checked September 29, 2026, lists $0.140 per second at 480p and $0.800 per second at 1080p without video references.
Five direct 1080p candidates: 5 × 4 seconds × $0.800 = $16.00.
Five 480p Drafts plus one 1080p Final: (5 × 4 × $0.140) + (1 × 4 × $0.800) = $6.00.
Difference in this example: $10.00, or 62.5% less than generating all five candidates directly at 1080p.
This is a calculation using the stated rates, not a billed test or a guaranteed saving. Video references, longer clips, additional Finals, retries, and account-specific terms change the total. Confirm your current quote before submitting.
For your own estimate, separate exploration from delivery:
Draft-to-Final budget =
(Draft count × Draft seconds × Draft rate)
+ (Final count × Final seconds × Final rate)
The example uses a fixed four-second duration. If you choose dynamic duration (duration=-1), the documented billing flow includes a 30-second pre-charge and later settlement. Read the model’s billing documentation before estimating available balance for that option.
When does Draft to Final make sense?
Use this workflow when you need to compare several ideas but will only finish a small number of them. It is less compelling when you already have one settled concept or need every candidate at 1080p.
With the same four-second, no-video-reference rates used above, one Draft plus one Final costs $3.76, compared with $3.20 for one direct 1080p generation. The extra $0.56 buys a review step; it does not save money in that one-candidate scenario.
Before starting, decide how many Drafts you will review, how many Finals you actually need, and which visible defects would make you reject a candidate. That decision is more useful than targeting a savings percentage.
When should you make another Draft?
Use specific feedback to decide your next step. “The camera move works, but the handle changes shape” tells you more than “the video looks wrong.” Keep the successful part of the brief and change the instruction most closely related to the failure.
If no candidate meets your requirements, stop and revise the brief before starting another bounded round. If a candidate works at 480p but the Final fails on fine details, account for another generation in your budget. A first Final is not guaranteed to be usable footage.
Frequently asked questions
Is a Seedance 2.5 Draft free?
No. Draft generation is billable, and a Final has its own generation charge. Check the displayed estimate before each submission.
Can I change the prompt when creating a Final?
The API Final request inherits the Draft’s generation settings. To change the creative direction, revise the prompt and generate a new Draft.
Will the Final look exactly like the Draft?
Do not assume frame-for-frame identity. Use the Draft to select a direction, then check the Final at the resolution and placement where it will be used.
Try the workflow with a clear budget
Start with a short brief, a small candidate count, and one planned Final. Open the Seedance 2.5 Playground to explore the controls, or follow the Seedance 2.5 API guide to build the same selection step into a production workflow.
