Kling 3.0 4K prompts for UGC and product ads

Kling 3.0 4K is the model to reach for when the clip is a final cut. It outputs 4K, supports text and first-frame starts, generates native audio, and lets you choose any length from 3 to 15 seconds.

That flexibility changes how you write. Match the prompt to the length you pick: a 5 second clip carries one action, a 12 second clip can carry a hook, a demo and a close. At 125 credits per second, an 8 second 4K render costs 1000 credits, so run a lower tier first when you are still testing the script.

The Kling 3.0 4K model page covers access and features, and the UGC ad templates give you full scripts by niche and format.

   Coffee brand product ad

   6 seconds, 9:16, 4K · 750 credits

   Vertical 4K macro-to-medium shot in a sunlit kitchen. A hand sets a matte black pour-over kettle on the counter, steam curling in the light. A woman in a cream sweater lifts a stoneware mug and says, "This is the only part of my morning that is never rushed." Slow push-in, shallow depth of field, kettle and pour sounds.

   Skincare testimonial

   10 seconds, 9:16, 4K · 1250 credits

   A woman in her 30s faces the camera in a bright bathroom, hair in a clip, holding a white pump bottle of moisturizer. She says, "I wanted something light that still lasts all day, and this finally did it." She pumps once, spreads it across her cheek and looks pleased. Soft window light, steady framing, quiet bathroom ambience.

   12 seconds, 9:16, 4K · 1500 credits

   Top-down 4K shot of a desk. Two hands slide the lid off a slim white box and lift out a pocket-size wireless speaker in sage green. A man's voice says, "Packaging is tight, the speaker feels solid, and it paired in about ten seconds." He sets it upright, taps it, and a soft chime plays. Clean desk, soft overhead light.

   Over-the-shoulder shot of a laptop on a cafe table showing a tidy project board with three columns. A woman drags a card from the first column to the last and says, "Everything I owe a client lives on one screen." She sips her drink and nods. Warm cafe light, murmured background chatter, light keyboard taps.

5. 5. Before and after

   Kitchen organizer reveal

   8 seconds, 9:16, 4K · 1000 credits

   Locked vertical shot of an open kitchen drawer full of loose utensils. A hand places a bamboo drawer organizer inside and sorts spoons, whisks and a peeler into it. The drawer slides shut smoothly. A voice says, "Thirty seconds, and I can find everything." Natural kitchen light, wood and metal sounds.

   10 seconds, 9:16, 4K · 1250 credits

   Handheld vertical video in a small home gym. A man in his 20s wraps a resistance band around his thighs, does three squats and looks at the camera. He says, "Ten minutes before work, and the band lives by the door." He drops the band into a canvas bag. Morning light through a window, breathing and floor sounds.

   Apparel try-on

   7 seconds, 9:16, 4K · 875 credits

   Mirror-style vertical shot of a woman in a camel wool coat over a black knit dress, turning slowly in a bright hallway. She runs a hand down the lapel and says, "It's warm, it drapes well, and it goes with everything." She turns back to the camera and smiles. Soft diffused light, quiet footsteps on wood.

   Medium shot of a founder at a workshop bench holding a small boxed leather wallet. She says, "First batch ships this week, and the link is below." She taps the box and points down. Warm tungsten light, tools softly out of focus, calm workshop sound.

• Pick the duration before you write

  Every length from 3 to 15 seconds is available. Write one action per 3 to 4 seconds and the pacing stays natural.

• Keep the prompt under 2,500 characters

  That is the model limit. Lead with subject and setting, then camera, then the spoken line, and cut adjectives that repeat.

• Quote the dialogue

  Native audio follows what you put in quotation marks. Name the speaker and the tone, such as calm, excited or deadpan.

• Start from a first frame for exact products

  Image-to-video from a clean product photo keeps labels and shapes consistent. Describe only what moves.

• Draft on a cheaper Kling tier

  Kling Video 3.0 Standard renders 8 seconds at 720p for 320 credits and Kling Video 3.0 Pro renders 1080p for 480. Move to 4K for the approved script.
