Kling Video V2 Master
Kling Video V2 Master is a text-to-video creation endpoint in the Kling family. It is built for creators who need to turn a concrete creative brief into a controlled visual sequence: the request establishes the source material, the intended subject behavior, the camera language, and the atmosphere of the finished shot. The standard route keeps that workflow explicit instead of hiding its input assumptions behind a generic video-generation label.
In practice, this route accepts a written prompt as creative context and exposes duration, aspect ratio for delivery planning. That makes it suitable for shot-based pipelines where teams must preserve a source, direct a transformation, or control the final format without losing sight of the model's central task. Write prompts as a compact shot plan—subject, action, setting, camera, light, and timing—then use the structured fields for constraints that should remain deterministic across iterations.
Highlights
- Prompt-to-scene generation. Builds the shot from written direction, including subject action, environment, lighting, lens language, and pacing.
- Controllable shot length. Duration or frame-count controls make timing an explicit part of the generation brief.
- Format-aware framing. Selectable canvases cover cinematic, landscape, square, and portrait delivery formats.
- Temporal coherence. The Kling generation path is designed around continuous motion across a shot, not a collection of unrelated frames.
Pricing
The request price is calculated with params.duration * 0.28.
| Configuration | Price |
|---|---|
| duration=5 | $1.400000 |
| duration=10 | $2.800000 |
The model card records a base price of $1.400000; the formula above determines usage-priced requests.
When to Use
| Scenario | Recommendation |
|---|---|
| Choose this route | Use it when the deliverable specifically calls for text-to-video creation, rather than a neighboring generation mode. |
| Prepare the source | Provide a precise written brief in the format described by the request schema. |
| Direct the shot | Describe the subject, action, environment, camera movement, lighting, and temporal progression in that order. |
| Control continuity | Use endpoint frames, reference media, strength, or audio controls when those fields are available instead of burying hard constraints in prose. |
| Plan delivery | Set duration, frame count, resolution, and aspect ratio explicitly when the schema exposes them, then compare iterations with a stable seed where supported. |
Prompt Guide
For text-to-video creation, describe one coherent shot rather than a list of visual keywords. Put the main subject and action first, follow with location and staging, then add camera movement, lens or framing, lighting, mood, and any timed change. Keep URLs and hard delivery choices in their dedicated fields.
