Use cases

Short drama episodes

Fit a full scene into one 30-second take, and reuse the same saved face and voice so the cast holds from episode to episode.

Product films and ad remakes

Reference the pacing and camera moves of an ad that already performs, then swap in a new product, lit and framed your way.

Dialogue in any accent

Write the exact line and name the accent, from Australian to Cantonese, and it comes back lip-synced in stereo.

Titles and signage

Quote the words in the prompt and they render legibly on signs, packaging, and title cards, holding steady as the camera moves.

Long single takes

Follow a subject through one continuous move, with tracking and orbit shots held steady from the first second to the last.

High-volume social clips

Kling 4.0 Flash handles the weekly batch: quick 720p takes for testing hooks and formats before you commit to a full render.

Overview

Kling 4.0 is Kuaishou's next video model, announced in the official Kling 4.0 release note on September 27, 2026, with the full launch in October. It makes 3 to 30 second clips at up to 4K, follows up to 10 keyframes, and takes up to 15 references across images, video clips, saved elements, and voice.

What Kling 4.0 does differently

Kling 4.0 gives one generation more time and more control. A full 30-second scene fits in a single take, keyframes place each beat where you want it, and references keep faces, products, and voices steady from shot to shot. Kling 4.0 Flash, the fast 720p tier, covers drafts and high-volume clips.

Kling 4.0 on Morphic

Kling 4.0 and Kling 4.0 Flash are coming to Morphic after Kuaishou's release. Until then, Kling 3.0 and Kling O3 are live in the video model picker alongside Seedance, Veo, and MiniMax, so you can build a scene on the Canvas today and compare takes side by side.
