Kling 4.0: What Was Announced, and Where SceneMixer Fits
Updated October 15, 2026
The announced specifications
This is the full Kling 4.0 specification as announced on September 28, 2026, restated from the release material. Where an item was announced as later work, it says so.
| Announced | Kling 4.0 |
|---|---|
| Take length | 3–30 seconds in one generation; extension to 2 minutes marked coming soon |
| Resolution | 720p, 1080p and 4K; 10-bit HDR at 1080p and 4K marked coming soon |
| Aspect ratios | 21:9, 16:9, 1:1, 9:16, Auto |
| Frame control | First and last frame, plus up to 10 keyframes anywhere on the timeline |
| References | Omni Reference, up to 15 per task: 10 images, 5 videos (30 seconds combined), 7 subjects (up to 3 video subjects), plus a voice |
| Audio | Stereo, tighter lip sync; dialogue and on-screen text in 9 languages with accents and dialects |
| Editing | Up to 5 input clips (one main), 30 seconds in total; single expression, camera, background or line re-edits |
| Prompt | Up to 8,000 tokens |
The number that matters most for series work is the take length. A beat that used to be two or three generations can be one, and the joins between takes — where framing, light and faces drift — get fewer.
Announced for later, and simply unknown
Three items in the announcement are explicitly later work: extension to a 2-minute maximum, 10-bit HDR at 1080p and 4K, and the full model's release itself (announced for October, no date).
Two things are unknown rather than promised: pricing (nothing published for either model) and the API (not open at the time of writing). Any per-second figure you see for Kling 4.0 today is not an official number.
Kling 4.0 or Kling 4.0 Flash?
Flash is the 720p, 3–20 second, 8-bit SDR model positioned for high-frequency creation, with first-frame image-to-video and Omni Reference (limits not announced) and no keyframe or editing layer in the announcement. Kling 4.0 Flash in detail.
If you need takes past 20 seconds, output above 720p, keyframes to pin a beat, or the editing pass, the announced answer is the full model. The two are compared line by line in Kling 4.0 vs Kling 4.0 Flash.
Where SceneMixer fits
This site starts one level up from a single clip: a script is read into an episode outline, the cast is drawn once as reference images, each episode gets a storyboard of numbered shots with their seconds and their lines, and those shots render segment by segment into one file per episode. The video models available here — Wan 3.0, Seedance 2.5, Seedance 2.0 and MiniMax H3 — are chosen per segment, and each carries its own price per second on the pricing page.
That layer is the part a new model plugs into rather than replaces: cast sheets keep a face across episodes, the storyboard decides what each shot contains, and the composite joins whatever the segments produced. How to make an AI short drama walks the whole pipeline.
If you are deciding today
- Wait for the full model if your shots need pinned beats, 4K or long takes — and you can hold the work until the October release actually ships.
- Consider Flash when it opens more widely if your destination is a phone feed and your takes fit inside 20 seconds.
- Do not plan around prices yet. Neither model has published one, and no official per-second rate exists to compare.
- Start the story now. Script, cast and storyboard are the parts that survive whichever model renders the shots.
