# Kling 4.0 vs Kling 3.0

URL: https://dreambench.ai/compare/kling-4-0-vs-kling-3-0

Pick Kling 4.0 for one take of up to 30 seconds, for dialogue in Portuguese, German, French or Hindi, or for a clip made straight from a prompt on DreamBench’s Video page. Keep Kling 3.0 for clips without sound, which use fewer credits, and for logo animation. Both make every scene of a Film Studio video.

## What changed from Kling 3.0 to Kling 4.0

Kling AI released Kling 4.0 in October 2026, eight months after Kling 3.0, and DreamBench runs both. Kling’s page for 4.0 and its user guides for the two models set out what changed:

- Length: one generation runs from 3 to 30 seconds, where Kling 3.0 stops at 15.
- Languages: dialogue in 9 languages instead of 5. Kling 4.0 adds Portuguese, German, French and Hindi to Chinese, English, Japanese, Korean and Spanish, and keeps the dialects and accents, such as Cantonese, Sichuanese and British or Indian English.
- Sound: two-channel stereo, generated with the picture on every clip. Kling 3.0 has a mode without native audio; Kling 4.0 has none.
- Motion: Kling says 4.0 holds movement steadier through fast fights, sport and large-scale action, and in contact between people and objects, while the camera tracks, orbits or pushes in.
- Control, in Kling’s own app: up to 10 keyframes along the timeline instead of a start and an end frame, up to 15 references in one generation, editing of an existing video, and creative recreation, which reuses a clip’s pacing and composition with new characters or products.
- Lettering: Kling marks text in several languages as new for 4.0, and says it stays readable as the camera and the scene move.

> Kling also describes a higher-resolution tier, 10-bit HDR and an extension to 2 minutes as coming soon. DreamBench renders both models at 720p and 1080p and doesn’t offer the extension.

Every row comes from the same tables as the [Kling 4.0](https://dreambench.ai/models/kling-4.0) and [Kling 3.0](https://dreambench.ai/models/kling-3.0) pages’ spec sheets, credits included, so it says what DreamBench offers today. The composer shows a video’s exact cost before you generate.

One difference the rows don’t show is where each model runs. Kling 4.0 is in two places: in Film Studio it makes every scene of a planned video, and on the Video page your prompt goes straight to it as one clip of 4 to 30 seconds. Kling 3.0 is in Film Studio only, because its route starts every clip from a picture, and the Video page takes words alone.

## Kling 4.0 vs 3.0 specs, from Kling’s own guides

**What Kling lists for each model in its own app and API, read on November 1, 2026**

|  | Kling 4.0 | Kling 3.0 |
|---|---|---|
| One generation | 3 to 30 seconds | 3 to 15 seconds |
| Resolution | 720p and 1080p, with a higher tier marked as coming soon | 720p and 1080p |
| Sound | Two-channel stereo on every clip | Native audio on, or a mode without it |
| Dialogue languages | 9: Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi | 5: Chinese, English, Japanese, Korean and Spanish; a line in another language is translated into English |
| Frames you set | Up to 10 keyframes: first, last or anywhere on the timeline | A start frame and an end frame |
| References | Up to 15 in one generation: images, videos, voices and elements | Elements built from 2 to 4 images or a video |
| Shots inside one clip | Multi-shot on by default in Omni Reference | A Multi-Shot switch, with custom shot counts and lengths |
| Editing a video you have | Yes, and creative recreation; extension coming soon | Not in the Video 3.0 guide |

DreamBench uses each model’s core: your prompt, or the opening frame DreamBench makes for each scene. Keyframes, Omni Reference, voice profiles and editing are features of Kling’s own app and API, and DreamBench doesn’t offer them with either model yet.

## Which Kling for which shot

**Which Kling do I need for this shot?**

- **A long take: a chase, a walk-and-talk, a product reveal:** Kling 4.0. One generation holds up to 30 seconds, so the action can build and land without a join. On the Video page, write the whole take as one prompt; in Film Studio, DreamBench still cuts a film into clips of 3 to 12 seconds.
- **Dialogue in Portuguese, German, French or Hindi:** Kling 4.0, the only one of the two that speaks them. Kling 3.0 translates a line in a language it doesn’t list into English. Neither lists Indonesian: for that, [Seedance 2.5](https://dreambench.ai/models/seedance-2.5) does.
- **A clip with no sound, to score or voice later:** Kling 3.0. Switch sound off and every second uses fewer credits. Kling 4.0 always generates sound, so you would pay for audio you then replace.
- **Fast action: a fight, a match, a dance:** Kling 4.0, which Kling built to keep bodies and contact steady through fast movement over a long take. Kling 3.0 was made for movement too, so a short move inside a 12-second Film Studio scene suits either.
- **One clip from a prompt, with no planning:** Kling 4.0 on the Video page: your prompt goes to the model as written and comes back as one clip, with no scene plan, cast or opening frame, so it costs less than a Film Studio video of the same length. Kling 3.0 isn’t on the Video page.
- **A logo that comes to life:** Kling 3.0, through the [logo animation](https://dreambench.ai/tools/logo-animation) tool, which runs on it: one short clip from your logo, with no scenes to write.

## What one does that the other doesn’t

#### Only Kling 4.0, on DreamBench

- A single clip of up to 30 seconds from the Video page, in 16:9, 9:16, 1:1 or 21:9.
- Dialogue in Portuguese, German, French and Hindi, on top of the 5 languages both speak.
- Stereo sound with every clip, with effects and ambience that follow the action.

#### Only Kling 3.0, on DreamBench

- Sound you can switch off, at a lower rate per second.
- Tools of its own: the logo animation tool runs on it, and the [Kling 3.0 prompt generator](https://dreambench.ai/tools/kling-prompt-generator) writes prompts in its grammar.

What both do: 720p and 1080p, the same five aspect ratios in Film Studio, where a clip takes the shape of its opening frame, up to 8 reference images a video, each tagged as a character, creature, location or prop, and a redo of any scene without remaking the rest. Both are on every plan.

## Writing a Kling 4.0 prompt after Kling 3.0

A Kling 3.0 prompt still works on Kling 4.0, but a 30-second take needs more in it. Kling’s 3.0 guide marks beats by the second (“At the 4th second”) or numbers the shots; its 4.0 guide sets an order: the overall settings first, meaning the place, the look and the camera, then a timed sequence of events, then the audio.

- Time the events in ranges that cover the whole clip: “From 0 to 10 seconds: …”, then “From 10 to 20 seconds: …”. A 30-second take needs three or four beats, not one.
- Write each spoken line in its own language, inside quotation marks, after a named speaker and how they say it: The vendor (cheerfully, in Brazilian Portuguese): “Olha a manga!” The same form works on Kling 3.0, in its 5 languages.
- Describe what is there rather than what isn’t. Kling’s 4.0 guide advises against negative instructions, with two exceptions worth keeping: no subtitles and no background music.
- On Kling 4.0, say what the clip should sound like, since it always makes sound. On Kling 3.0, switch sound off if the clip will be scored later.
- Ask for “one continuous take” when you want no cuts: Kling 4.0 may plan its own shots inside a long clip.

On the Video page a Kling 4.0 prompt can run to 2,500 characters, well under what Kling’s own app accepts, so keep the settings tight and spend the words on the events. In Film Studio, DreamBench writes each scene’s prompt for you. The [Kling 3.0 prompt guide](https://dreambench.ai/guides/kling-3-0-prompt-guide) covers camera terms and dialogue that carry over to 4.0.

## Should you move a Kling 3.0 video to Kling 4.0?

Kling 3.0 stays on DreamBench, so nothing you made or planned on it stops working. Move a video to Kling 4.0 when it needs what only 4.0 has: a take longer than 15 seconds, one of the four added languages, stereo sound or a single clip from the Video page. Stay on Kling 3.0 when the clip should be silent or when it is a logo.

A Film Studio video uses one model for every scene, so the two can’t share a video. To compare them on your own idea, make the same video twice, once on each, and keep the one you prefer. For how Kling 3.0 compares with models from other makers, see Veo 3.1 vs Kling 3.0 and Seedance 2.5 vs Kling 3.0.

> Kling 4.0 Flash, which Kling describes as faster and lower in cost, shows as Soon in DreamBench’s model menu and can’t be used yet. The Kling 4.0 you pick is the full model.

## Questions

- **Is Kling 4.0 better than Kling 3.0?** For long takes, fast action and dialogue beyond Kling 3.0’s 5 languages, Kling 4.0 is the one to pick: one generation runs to 30 seconds and it speaks 9 languages. For a clip without sound, Kling 3.0 still fits better, because its sound can be switched off, which uses fewer credits on DreamBench.
- **What is the difference between Kling 4.0 and Kling 3.0?** Kling 4.0 doubles one generation from 15 to 30 seconds, adds Portuguese, German, French and Hindi dialogue, makes stereo sound on every clip and, in Kling’s own app, takes up to 10 keyframes and 15 references and edits existing video. On DreamBench, Kling 4.0 is also on the Video page, while Kling 3.0 runs in Film Studio only.
- **Can I still use Kling 3.0 on DreamBench?** Yes. Kling 3.0 stays in Film Studio beside Kling 4.0, on every plan, at 720p and 1080p, with sound on or off. The logo animation tool also runs on it.
- **How long can a Kling 4.0 clip be compared with Kling 3.0?** Kling 4.0 renders 3 to 30 seconds in one generation and Kling 3.0 renders 3 to 15. On DreamBench’s Video page a Kling 4.0 clip runs 4 to 30 seconds. In Film Studio, DreamBench cuts a film into clips of 3 to 12 seconds on either model and joins them, up to 5 minutes on Ultra and Studio.
- **Does Kling 4.0 speak Portuguese and German?** Yes. Kling lists 9 languages for Kling 4.0’s dialogue: Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi. Kling 3.0 lists 5 and translates a line in any other language into English. Write the line in its language inside quotation marks and Kling 4.0 speaks it with lips in time.
- **Can I turn off sound in Kling 4.0?** No. Kling 4.0 generates stereo sound with every clip and has no silent mode, in Kling’s app or on DreamBench, so a second costs the same whatever you ask it to hear. Kling 3.0 can make clips without sound, at a lower rate per second.
- **Does Kling 4.0 cost more credits than Kling 3.0?** It depends on the resolution and on sound: Kling 4.0 always has sound, and Kling 3.0 uses fewer credits with sound off. The table on this page lists each model’s credits per second at 720p and 1080p, from the rates the composer quotes, and the composer shows a video’s exact cost before you generate.
- **Do Kling 4.0 and Kling 3.0 take a first and last frame on DreamBench?** Both models can work from a first and last frame, and Kling 4.0 takes up to 10 keyframes in Kling’s own app. DreamBench’s composer has no slot for your own start or end picture: in Film Studio it makes each scene’s opening frame from your reference images, and the Video page takes words alone.
