Kling v1.5
Kling v1.5 is a video model with a documented image-to-video workflow. Start from a prepared still and describe the movement, viewpoint and final composition for a short character, object or environment shot.
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 v1.5 is a Kling video-generation edition with image-to-video capability in the documented model catalogue. A supplied still provides the visual starting point, while the written brief describes how the scene should move. Use it to develop a character gesture, a moving object or a changing environment from an image whose composition already fits the shot.
Prepare the image around the subject’s important details. A character needs a readable face, pose and clothing; an object needs a clear outline and visible material features. Leave space in the composition for the intended movement. Keep the original still with the finished sequence so changes in appearance can be assessed directly.
Write the action as an observable event. For example, describe a seated person turning toward a window or a fabric ribbon moving in a gentle breeze. State the direction and the intended ending. When several objects appear, identify which one acts and which ones stay in place.
Explain the camera’s role. A fixed viewpoint can make a small gesture easy to inspect, while a moving viewpoint can reveal a new side of the scene. Describe that movement in relation to the subject. A request to approach the subject and a request for the subject to approach the camera produce different visual intentions.
The documented image-to-video entry lists five- and ten-second duration choices, std and pro modes, and landscape, portrait and square framing. Choose the settings offered for the selected workflow before evaluating the result. Keep the actual mode, duration and frame shape with the source image and prompt when comparing candidate shots.
For an object presentation, define the visual feature that the movement should reveal. It may be a reflective surface, the fold of a material or the shape of a handle. Keep the action focused enough that the important feature remains visible. Evaluate the object throughout the motion and at the final view used in the edit.
For a character scene, describe one meaningful gesture and the character’s relationship to nearby objects. Review the face, hands, clothing and body proportions over time. Check whether the gesture reaches its intended end and whether the scene keeps a coherent arrangement of foreground and background elements.
Retain the complete generated clip and its source materials. Review the opening, the central action and the ending as one sequence, then make revisions around a concrete mismatch. A note such as “the character turns away from the window” gives the next brief a specific correction while preserving the rest of the scene.

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
- Not specified When flex mode is selected
- Maximum reasoning effort
- Not specified When maximum reasoning effort uses the default adjustment

Prices by configuration
Match each charge to the conditions shown. Use one rate for each set of alternative configurations.
