What to make with the Kling 4 AI video generator

Longer scenes in one clip

With clips of up to 30 seconds, there is room for a whole moment: a product reveal, a short walk-through or a scene that builds. You plan one shot instead of stitching several short ones together.

Realistic motion for ads and social

Kling 4 is built for realistic motion, which fits everyday actions like coffee being poured, a jacket swinging as someone walks or a car pulling into a driveway. That suits product clips and short ads, where stiff movement hurts trust.

Turning photos into videos

Start from a product shot, portrait or illustration and let Kling 4 animate it. No good photo yet? Make one with the AI image generator, then bring it here to add motion.

How to use Kling 4: text or image to video

1
Write a prompt or add a photo
Open the video generator with Kling 4 selected. Describe the scene in a few clear sentences, or upload a photo and say how it should move.
2
Choose length, quality and shape
Pick a length (5, 10, 15 or 30 seconds), a quality (720p or 1080p) and one of 5 aspect ratios. A 30 second clip gives you room for a full scene, so save it for prompts you have already tested.
3
Generate and download
Press generate. Your finished clip is saved in your gallery, where you can watch and download it. If something looks off, change one detail in your prompt and try again.

Aspect ratios for every platform

Kling 4 supports 5 aspect ratios: 16:9, 9:16, 1:1, 4:3 or 3:4. Use 9:16 for TikTok, Reels and Shorts, 16:9 for YouTube and websites, 1:1 or 3:4 for feed posts, and 4:3 for slides and product pages. If your photo is the wrong shape, extend it first with the AI image resizer.

Kling 4 prompt tips

Describe who or what is in the shot, what they do, where it happens and how the camera moves.
For longer clips, describe the scene in beats (what happens first, next and last) so every part of the video has something going on.
Test a new idea as a short 720p clip, then make the long 1080p version once the prompt works.
For photo-to-video, start from a sharp, well-lit image, and run a soft one through the AI image upscaler first.

Example prompt

“A barista pours steamed milk into a latte in a sunny corner cafe, steam rising, as the camera slowly pushes in, then pulls back to reveal customers chatting by the window.”
