Kling O3 Pro v2v / Edit

Kling O3 Pro v2v / Edit is a video edit model. Rewrite an existing clip — replace the person, keep the scene. Replaces the person in a source video with your face from up to four photos, keeping the scene, camera and motion. People run it for: face swap, character replacement, video edit.

10 credits for a 5 s clip. It bills per second of output at 2 credits a second, so a shorter clip costs proportionally less. Billing stops at 15 seconds, so one run never costs more than 30 credits. Credits are the only unit we quote. One balance covers every model in the catalogue, so there is no subscription attached to Kling O3 Pro v2v / Edit specifically and no minimum spend to use it. See the pricing page for what a credit costs.

It accepts a video, an image and a text prompt. It will not start without a video, an image and a text prompt. Up to 4 reference images per run.

Every run returns one video. A single run gives you between 3 and 15 seconds. Audio carries over from the source rather than being regenerated. Runs are queued and processed in the background, so you can close the tab — the finished file turns up in your library. We do not quote a fixed wall-clock time: it moves with the length of the run and with how busy the queue is.

The catalogue also runs HappyHorse 1.0 Video Edit (20 credits for a 5 s clip), Wan 2.7 Edit Video (10 credits for a 5 s clip) and LTX 2.3 Reframe (10 credits for a 5 s clip) for the same job. HappyHorse 1.0 Video Edit is our default pick for video edit. They all draw on one credit balance, so trying a second one costs nothing beyond the run itself.
