Kling 4.0 Video Edit

Kling 4.0 video edit. Change an existing clip with a prompt — swap outfits, restyle the scene, regrade the colors — optionally guided by up to 10 style reference images. The output keeps the aspect ratio and the original audio of your video.

Refer to the source video in prompt as <<<video_1>>> and to reference images as <<<image_1>>>, <<<image_2>>> … in the order of image_urls.

Pricing — in tokens (USD at $0.02/token), billed on output seconds + max(source video seconds, output seconds):

resolution	tokens/s	USD/s
720p	6.11	$0.1222
1080p	9.165	$0.1833

The source video length is measured from your file before any tokens are charged, and rounded up to a whole second. With the default duration: "auto" the output is as long as the source, so a request is billed for twice the source length. Reference images are not charged.

Examples at 720p:

5-second source, duration auto: 10 billed seconds, 61.1 tokens (= $1.222)
10-second source, duration 20: 40 billed seconds, 244.4 tokens (= $4.888)

Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the edited video.

Not accepted by this model (rejected before any tokens are charged): ratio / aspect_ratio (the output follows the source video), sound / generate_audio (the output always keeps the audio of your video), negative_prompt, image_url / image_end_url / keyframes, and 4K.
