Kling 3.0 AI Video Generator

Write the prompt as one shot: who or what is in frame, what happens, how the camera moves and what the mood is. "A red sports car drifts around a wet mountain bend at dusk, low tracking shot, spray from the tyres, headlights glowing" tells the model the subject, the action, the camera and the light. Kling follows concrete verbs and camera terms better than abstract adjectives, so prefer "slow dolly in" to "cinematic".

You have up to 2,500 characters. When you animate a photo, spend the words on motion rather than on describing the picture again: the image already shows the subject, so tell Kling what should move, how fast and in which direction.

Kling 3.0 is priced per second, so duration is the setting that moves the price most. Use the shortest length that fits the action. A head turn, a pour or a reveal fits in a few seconds; a walk across a room or a long camera move needs more. A longer clip also gives the model more time to drift away from the prompt, so a short clip is often the sharper one.

For a video longer than one clip, generate several shots and join them in the AI video editor, or let the video agent plan the shots and generate them for you.

Generated sound is useful for ambience and effects: rain, traffic, a door closing, footsteps. It saves a trip to a sound library and makes a clip feel finished. If the clip will carry a voice-over, a song or a brand jingle, switch sound off: you pay less per second and do not have to mute the track later.

The price table on this page shows both cases side by side, so you can see what sound adds for each length and mode before you decide.

Start from a sharp, well lit image with the subject clearly separated from the background. Because the ratio follows the picture, crop it to the frame you want before uploading; the image cropper does this for free in your browser. If the photo is small, run it through the image upscaler first.

With a second image, Kling has a target for the end of the shot as well. Keep both pictures in the same ratio and describe the motion that connects them, and the result stays much closer to what you planned.

Every clip is generated on its own, so a character described only in words can change from one shot to the next. The reliable fix is to give each shot the same reference image: create the character once in the AI image generator, then start every clip from that picture and change only the action in the prompt.

Keep the wording that describes the character identical between prompts, and change one thing at a time when a take does not work. Small, deliberate edits make it much easier to see which word caused a change than rewriting the whole prompt.

On AgentReel a Kling clip costs 11 to 102 credits. The price is the per-second rate of the mode, with or without sound, times the duration. The table on this page lists every combination and the Generate button shows the exact figure before you spend anything; a failed clip is refunded automatically.

Credits come from a plan or credit pack. Free credits cover Z-Image, video templates and Code to Video only, so generating with Kling needs paid credits. The credits and pricing guide explains how plans and packs work.

Kling 3.0 stands out for its flexible length options and its sound switch. Veo 3.1 always generates sound, goes up to 4K and is priced per clip; Seedance 2.5 and MiniMax H3 add wider aspect ratios such as 21:9; Wan 3.0 costs less than either Seedance model at every resolution. The comparison table above lists every model in the generator with its credit range.

All of them live in the same AI video generator, so you can run one prompt on Kling and on another model and keep the better clip. The model overview has a page for each of them.
