What is Kling V3 Omni?
Kling V3 Omni is the reference-driven model in Kuaishou's Kling V3 generation. Where Kling V3 works from a prompt or one or two frames, Omni takes up to 7 reference images in one generation and lets you say in the prompt what each one is — the subject, the scene, a costume, a prop or a style. That is the job it does best: putting the same character, product or set into a new shot without having to describe how it looks every time.
It has three modes: text-to-video, image-to-video from a first frame, and reference-to-video. In reference mode you can also attach one reference video of up to 10 seconds to carry a movement or a camera move; with a video attached the image limit drops to 4. Clips run any whole number of seconds from 3 to 15, in 16:9, 9:16 or 1:1, and sound is a switch that does not change the price.
Output comes in three tiers: 720p, 1080p and 4K. The price is 8 credits per second at 720p — 40 credits for a 5-second clip, 80 for 10 and 120 for 15. 1080p costs 1.6 times as much (64 credits for 5 seconds) and 4K costs 4.75 times as much (190 credits for 5 seconds, 570 for 15). The 4K tier works with text, a first frame or reference images, but not with a reference video. A reference video is billed by its own length at the clip's per-second rate, on top of the output: a 2-second reference adds 16 credits to a 720p clip. Reference images are not charged.
The supplier limits prompts to 2,500 characters, so keep the description of each reference short and specific — name the role, not every detail the image already shows.
Choose V3 Omni when a shot depends on several reference images, when you want 4K, or for character work you will repeat across clips. Its image-side sibling, Kling Image 3.0 Omni, applies the same multi-reference idea to stills, so the frames you make there can feed the video. Choose Kling V3 instead when you need first-and-last-frame control, which Omni does not offer, and Kling V4 for takes longer than 15 seconds, stereo sound on every clip or more reference material. Both have their own pages.
