Kling v2 Master

Kling v2 Master creates short video scenes from text or an image-led brief. Its documented model entry lists five- and ten-second duration choices and several frame shapes for building a shot around a clear action and ending.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Kling v2 Master is a Kling video model with text-to-video and image-to-video capability in the documented catalogue. Use a written brief to develop a new scene, or start from an image that establishes its appearance. Give each shot a defined purpose, such as introducing a location, showing an interaction or revealing an object detail.

For a new scene, describe the main subject, its surroundings and the movement the viewer should follow. Include important physical relationships: an object on a table, a person beside a doorway or a vehicle approaching a bend. These details make the intended event easier to assess in the completed video.

For an image-led shot, prepare the reference with the desired subject and framing. Keep distinctive edges, facial features and materials visible. Describe what moves from that view and what the final composition should contain. Use the original image when checking whether the subject remains coherent throughout the sequence.

The documented model entry lists five- and ten-second durations. Plan the action so its opening, development and ending fit the selected shot length. A brief gesture and a camera-led reveal have different pacing needs. Check the actual clip for an ending that can be used in the intended edit.

The documented model controls include std and pro modes, alongside landscape, portrait and square framing. Select the options offered for the workflow and preserve their values with the result. Frame the important subject for the destination so its decisive action remains visible during movement.

Describe camera motion through its relationship to the subject. A camera passing an object reveals different information from an object turning in front of a fixed camera. State the intended movement clearly and keep it connected to the visual feature or story beat the audience needs to notice.

Inspect the complete sequence for continuity, interactions and timing. Watch the subject’s shape, contact with nearby surfaces and position within the scene. For a character, check the face, hands and clothing across the action. For an object, check its outline and material appearance as the view changes.

Retain the finished video, prompt, reference and settings as one shot record. Compare candidates using the same viewing conditions and the same visual goal. When revising, identify the observed mismatch, preserve the useful parts of the scene and change the instruction that addresses that specific problem.

How the final charge is calculated

The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.

Tariff references do not add request options. Supported parameters are listed for the selected method.

Fast mode
Not specified When fast mode is selected
Flex mode
