Model tiers: standard renders 720p, pro renders 1080p, 4k renders 3840x2160. Durations run 3 to 15 seconds. Native audio is on by default; turning Sound off bills the lower rate on standard and pro, while 4K includes audio at one flat rate. Image-to-video accepts one or two images (first and last frame) and follows the source image size.
Motion-control video: a reference IMAGE (the character/subject) and a reference VIDEO (the motion source) are BOTH required. The character from the image performs the movements from the video.
Kling V3 runs through POST /v1/videos/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Both models are called through the same endpoint. Set model to kling-v3 or kling-v3-motion-control. Get an API key from the EmpirioLabs dashboard.

Yes. Both models use POST /v1/videos/generations with the same EmpirioLabs API key, so most integrations switch by changing the model value. Check the parameters table on this page first if you rely on a model-specific parameter.
Yes. Open each model in the EmpirioLabs playground and run the same prompt on both, with the parameters the API exposes.
