References for a single scene
Give each reference a clear role: character, object or environment. Explain which traits should stay and what should change. One well-prepared image is enough for an initial test.

Kling O1 Video — references and keyframes for video
Kuaishou introduced Kling O1 as a multimodal generation and editing system. This runblob page brings together available reference-based video generation and a separate start-and-end-frame version.
Capabilities
A transition between two frames
For the Frames version, prepare the beginning and end of the scene. Align subject placement, lighting and perspective, then describe the transition. A clear relationship between frames makes it easier to judge whether the motion matches your plan.
How to integrate the API
To integrate the Kling O1 API, select the exact version and settings in the playground. The generated cURL includes the endpoint, request fields and required Bearer authorization type. Move the request into your server code; keep secret keys out of the browser. References use service-accessible URLs rather than local file paths.
Pricing and generation budget
Compare Kling O1 API costs separately for reference generation and Frames. Duration and mode affect the estimate. If an ending matters, a prepared final frame helps test your intent without relying on random endings, although exact matching is not guaranteed.
Comparing versions and workflows
O1 References uses visual materials to guide a scene; O1 Frames specifies its beginning and end. Choose by your inputs, not price alone. Compare O3 separately for a newer multi-reference family, using the same scene and duration.
Use cases
Transitions between two compositions
Clips with a preselected character
Animation tests for a storyboard
Image and video examples
Prompt examples and workflows
Opening a package
Connect the closed-box starting frame to the open-box ending frame. The lid slowly rises, with a static camera and unchanged light and background.
Frames requires two prepared images with consistent perspective.
A lighting transition
Transition smoothly from the room’s daylight starting frame to its evening ending frame. Keep furniture still as the light gradually warms, without changing the viewpoint.
Matching object positions makes the transition easier to assess.
An object and its setting
Use the bag from the first reference and the terrace from the second. The bag rests on a table while a breeze moves nearby fabric. The camera slowly approaches.
This reference-mode example assigns a distinct role to each image.

Versions and pricing
Runblob prices in USD. The final cost depends on the selected version and request parameters. Public rates refresh every six hours; personal rates are available in your dashboard.
Playground
Configure the parameters and build an API request. Sign in to runblob to start a generation.
How to integrate
- Sign in to runblob and open the model’s playground.
- Choose a version, format and parameters. Check the cost before starting.
- Submit your request and retrieve the result. Authentication and status endpoints are described in the model documentation.
Frequently asked questions
How do I provide start and end frames?
Choose the Frames version in the playground and add images to the corresponding fields. Then describe the transition and select an available duration.
Do two frames require Motion Control?
No. Frames defines the starting and ending images. Motion Control is a different workflow: it takes movement from video and transfers it to a character.
Should I choose O1 References or O1 Frames?
O1 References uses visual materials to guide a scene; O1 Frames specifies its beginning and end. Choose by your inputs, not price alone. Compare O3 separately for a newer multi-reference family, using the same scene and duration.
How do I connect Kling O1 to my application?
To integrate the Kling O1 API, select the exact version and settings in the playground. The generated cURL includes the endpoint, request fields and required Bearer authorization type. Move the request into your server code; keep secret keys out of the browser. References use service-accessible URLs rather than local file paths.
How can I compare pricing and find an affordable Kling O1 API?
Compare Kling O1 API costs separately for reference generation and Frames. Duration and mode affect the estimate. If an ending matters, a prepared final frame helps test your intent without relying on random endings, although exact matching is not guaranteed.
