Key Features of Kling 4.0 AI Video Model
Make a full 30-second video in one go
Kling 4.0 makes videos up to 30 seconds long from a single prompt. Kling 3.0 stopped at 15 seconds. That extra time fits a whole story, like an ad that opens on a problem, shows the product, and ends on your logo. Plus, the Extend Video tool continues your video for up to 2 mins without losing visual consistency.
Try it NowSet up to 10 keyframes across your video
Kling 4.0 AI video generator lets you upload up to 10 keyframes, which are pictures of the moments your video must show. Use 2 keyframes to set the first and last shot, or use all 10 to plan the whole video shot by shot. Kling 4.0 fills in the motion between them. Your character and setting stay the same from one keyframe to the next.
Try it NowUse up to 15 references in one video
Kling 4.0 takes up to 15 references at once, including up to 10 pictures, up to 5 video clips, and voice samples. A face photo sets how your character looks, a clip sets how they move, and a voice sample sets how they sound. Save that person in OpenArt Characters to use them again in your next video.
Try it NowVoice your characters in 9 languages
Kling 4.0 makes spoken dialogues in English, Spanish, Portuguese, French, German, Hindi, Chinese, Japanese, and Korean. You can also ask for an American, British, or Indian accent, or a Chinese dialect like Cantonese. The voices sound like real people from that place. You can make localized versions of your video without hiring a voice actor.

Best Use Cases of Kling 4.0
Short drama and animation studios
Short drama studios need the same character to look and sound the same in every episode. Kling 4.0 fits a full scene into one 30-second video, and a saved face and voice carry into the next one. When one moment in a scene looks wrong, edit just that moment. The rest of the episode stays exactly as it was.
Try it NowAd teams making product and brand videos
Ad teams can upload a video ad that already performs well and have Kling 4.0 copy its pace and camera moves with a new product. The product name and price show up as clear text inside the video. The same ad can then speak Spanish or Hindi for a new market. One winning ad idea turns into many versions to test.
Try it NowMusicians making music videos
Musicians can upload their own photos, a style picture, and the song as references. Kling 4.0 makes music video clips where the artist appears in every shot and the look stays the same. Keyframes let you line up the biggest moments with the chorus. You can fix any shot you do not like without making the whole clip again.
Try it NowSocial media creators posting every week
Social media creators post often and rarely have a crew or a set. Upload one photo of yourself and a video you like, and Kling 4.0 makes a new clip with you in it. Kling keeps the cost low when you need a lot of videos in one week. You can post more often without booking a single shoot.
