Skywork AI SkyReels V3 Extend Video Cutshot

Skywork AI SkyReels V3 Extend Video Cutshot continues an existing video clip with newly generated footage while allowing control over shot transition behavior through cut_type. Upload a source video, describe how the scene should evolve, and generate an extension that continues the story with smoother or more intentional cut-style progression.

Why Choose This?

Video continuation with shot control Extend an existing clip while influencing how the continuation is cut or transitioned.
Prompt-guided scene evolution Describe what should happen next using natural language.
Cut-style flexibility Use cut_type to control how the model handles the continuation shot structure.
Simple workflow Upload one video, write a prompt, choose cut behavior and duration, then generate the extension.
Production-ready API Suitable for scene continuation, short-form storytelling, product demos, and creative editing workflows.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of how the video should continue.
video	Yes	Source video to extend.
cut_type	No	Shot transition or cut behavior for the extension. Default: `Auto`.
duration	No	Extension duration in seconds. Default: `5`.

How to Use

Upload your source video — provide the clip you want to continue.
Write your prompt — describe what should happen next in the scene.
Choose cut type (optional) — use Auto or another supported cut mode to guide the transition style.
Set duration (optional) — choose how long the extension should be.
Submit — run the model and download the extended video.

Example Prompt

The woman was engrossed in reading when, amidst a thunderstorm outside, all the lights inside suddenly went out.

Pricing

Pricing is based on duration.

Duration	Cost
5s	$0.20
10s	$0.40
15s	$0.60

Billing Rules

Base price is $0.20 per 5 seconds
Pricing scales linearly with duration
Total price = $0.20 × duration / 5
cut_type does not affect pricing

Best Use Cases

Scene continuation — Extend an existing shot into the next beat of the story.
Shot-aware storytelling — Control how the continuation feels from a transition or cut perspective.
Product demos — Continue a product interaction with more structured shot progression.
Creative prototyping — Test alternate continuations with different cut behaviors.
Short-form editing — Build longer sequences from shorter source clips.

Pro Tips

Keep the prompt focused on what should happen next in the scene.
Use Auto when you want the model to choose the most natural continuation.
Try different cut_type settings when pacing or shot feel matters.
Start with shorter durations to validate the continuation before generating longer results.
Use a clear source video so the extension has a stronger visual anchor.

Notes

prompt and video are required.
cut_type defaults to Auto.
duration defaults to 5.
Pricing depends only on duration.
