Kling v3.0 Standard text-to-video generates high-quality videos from text prompts with smooth motion, cinematic visuals, precise prompt adherence, and optional native audio co-generation. Supports 3-15 second duration and multiple aspect ratios.
This is an async API that only returns the task_id of the async task. Use the task_id to call the Get Async Task Result API to retrieve the generated result.
