The documented video workflow also includes an optional sound setting for this edition, allowing the scene’s visual action and sound intention to be planned together. - [**Ailoot Ultra · Video** `POST /v1/videos` `kling-v2-6`](https://ailoot.ai/models/en/kling-v2-6/#method-0) 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 v2.6 is a Kling video model with text-to-video and image-to-video capability. The documented workflow includes a sound option for this edition. Plan the visible event first, then describe the audio intention when using a workflow that exposes that control. Keep the relationship between what the audience sees and hears clear. A useful text brief identifies the subject, setting, action and camera viewpoint. Describe a concrete event such as a person opening a wooden gate, waves reaching a stone shoreline or a small machine moving on a workbench. State the important visual details and the sequence in which the action should happen. An image-led brief begins with a prepared still. Use a reference that shows the subject’s distinguishing features and the intended composition. Explain how the subject, environment or viewpoint should move from that starting frame. Retain the original image so the generated sequence can be compared with its actual visual source. Treat sound as a separate creative decision. The documented sound control has on and off choices and defaults to off in the published workflow. Record the selected setting with the result. When sound is part of the shot, describe its relationship to the visible event and listen to the completed clip alongside the image. The documented model entry lists five- and ten-second durations, std and pro modes, and landscape, portrait and square frame shapes. Choose the options offered by the selected workflow. Keep the actual duration, mode and framing consistent when comparing candidates for the same scene. For an action with an audible event, identify its timing in the brief. A gate closing, an object touching a surface or a wave breaking each has a specific visual moment. Inspect whether the finished clip’s sound supports that moment and the overall scene. Retain the completed media when preparing the edit. Review visual continuity through the entire sequence. Check subject shape, appearance, contact with nearby objects and the camera’s movement. Then review any sound separately for timing and suitability. The final shot needs a useful opening and ending as well as a readable central action. Save the prompt, reference, selected settings and finished clip together. When a revision is needed, distinguish the observed visual issue from the observed sound issue and change the instruction connected to it. Preserve successful scene details so the next candidate answers a specific creative question. **Ailoot Ultra · Video** `POST /v1/videos` `kling-v2-6` [`kling-v2-6`](https://ailoot.ai/models/en/#m=kling-v2-6&route=Ultra&caller=kling-v2-6&fmt=videos) Kling /`kling-v2-6` ### Overview Kling v2.6 generates video from text or an image-led brief.

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 #### Estimated rates for comparison #### Prices by configuration Match each charge to the conditions shown. Use one rate for each set of alternative configurations. | Configuration | Rate schedule | Forecast quantity | Charge | | --- | --- | --- | --- | | ConfigurationBase token rates | Rate scheduleBase rate | Forecast quantity— | Charge Input · Input tokens · Estimate for comparison only **—** / 1K tokens Output · Output tokens · Estimate for comparison only **—** / 1K tokens Input · Cache read · Estimate for comparison only **—** / 1K tokens Input · Cache write · Estimate for comparison only **—** / 1K tokens Input · Cache write, 1 hour · Estimate for comparison only **—** / 1K tokens | | ConfigurationEstimated generation cost | Rate schedule— | Forecast quantityone generation estimate | Charge Output · Estimated generation cost · Estimate for comparison only **$6** estimate before generation This estimate is not an additional charge or a fixed rate for the completed generation. | Ailoot reserves an estimated amount before a request.
