Kling 4

Why creators choose Kling 4

Kling 4 generates new footage and edits existing clips, with sound in every mode. Start from a description, choose opening and closing frames, or carry your characters and products into new scenes through picture and video references.

Several shots in one generation

A shot list gives each shot its own brief and duration, with a total of 3 to 30 seconds. Keeping a dialogue exchange or connected product sequence in one generation helps continuity across cuts and gives you one price for the sequence. Separate clips still make sense when you want to review or replace each shot independently.

Your characters and products, shown from several sides

Plain pictures guide identity, products, locations and style. Elements group several views of one character or object, or one video of it, so the model can follow that subject as it turns. Reference generation supports up to seven elements, including up to three video elements.

Characters that speak in a chosen voice

Assign voices to up to three elements in reference generation, including voices created with Kling Voice Clone. This helps a recurring character sound the same across scenes.

Video references for motion and camera direction

Reference-to-video accepts up to five videos alongside up to ten pictures. Use footage to guide movement, camera language or a look to follow, while the prompt directs the new scene. Each reference video runs 3 to 30 seconds, and their combined length cannot exceed 30 seconds.

Start and end on the frames you pick

Image-to-video starts from a first frame and can aim for an optional last frame, following the first frame's shape. Reference generation can also take a first frame when the opening needs to match a particular image.

Edit footage instead of reshooting

Video editing changes an existing clip under an instruction and returns the source's length. Swap a product for the one in a photo, change the setting or alter a detail. Up to ten pictures and seven image elements can show what goes in, including several views when an object turns.

How to use Kling 4 in Craze

1. Start a project and describe the video. Upload frames, picture or video references, or the clip you want to edit.
2. Ask for Kling 4, or let Craze show you compatible models and prices.
3. Choose resolution, shape and length for new footage. For several shots, describe each shot and its timing; for an edit, say what changes and what stays.
4. Craze generates the clip. Review its picture and sound, then assemble it on the timeline.
5. Refine the cut and export when ready.

Kling 4 capabilities

Kling 4 supports text-to-video, image-to-video, reference-to-video and video editing at 720p or 1080p. All modes generate sound. New clips run 3 to 30 seconds. Text and reference generation support 16:9, 9:16, 1:1 and 21:9. Image-to-video follows its first frame; an edit follows the source footage.

Text, image and reference generation support explicit shot lists. Each shot lasts at least one second and has a prompt of up to 512 characters; the sequence totals 3 to 30 seconds. A single prompt supports up to 26,000 characters.

Reference generation accepts up to ten pictures, five videos, an optional first frame and seven elements. An element uses a front picture plus one to three more views, or one video of the same subject. Up to three elements can carry voices, and up to three can be video elements. Editing accepts a 3 to 30-second source, up to ten pictures and seven image elements, each with a front picture plus one to three more views.

Kling 4 pricing

Clips start at $0.166 per second of video. 1080p costs more per second than 720p. Text-to-video, image-to-video and reference generation using pictures share an output-based rate, including sound.

A video reference or video element changes the billing basis to reference footage plus output length, with a minimum of twice the output length. Editing counts source plus output, so the billed duration is twice the source length. Use the calculator for your task and references.

Who Kling 4 is for

Ads and product videos

Reference pictures and image elements help keep a product's design consistent, including surfaces revealed by a turn. A 30-second generation can hold a complete spot.

Stories with recurring characters

Elements keep a character's views together, assigned voices carry their sound, and shot lists let you direct coverage within one generation.

Fixing footage after the fact

When a client wants a different product, background or detail, edit the clip you have while keeping its length.

Kling 4 vs other Kling models

Kling 4 is Craze's current Kling recommendation for text, image and reference generation, and video edits. Kling O3 Pro retains a separate video-to-video-reference route. Kling 3 Standard offers motion control, which Kling 4 does not. For 4K output, see Kling O3 4K or Kling 3 4K.
