What you can do with Kling 4.0 on this page

Kling 4.0 is the newest generation of the Kling video model, built for cleaner detail, subjects that stay consistent from the first frame to the last, and steadier motion when the action speeds up or the camera travels through the scene. This page puts it to work with no setup: the generator above takes a written prompt, a single photo or a pair of frames and returns a short clip you can watch, download and reuse.

Everything happens in one place. You choose how the shot should start, describe what moves and how the camera behaves, then set the length, resolution and aspect ratio. The estimated credit cost updates as you change those settings, nothing is charged until you press Generate, and if a generation fails the credits go back to your balance automatically. The sections below explain each mode, show how to write prompts that hold up in motion, and walk through the settings so your first renders land closer to what you had in mind.

Three ways to start a Kling 4 video

Pick the mode that matches the material you already have. You can switch at any time in the generator, and the upload slots change to fit the mode you choose.

Text to video

Start from a blank canvas when all you have is an idea. Describe the subject, the setting, the action and the camera, and the model builds the whole shot from your words. It is the quickest way to explore a concept, test a mood or sketch a scene before you settle on a look.

Image to video

Upload a photo, an illustration or a product shot and use it as the opening frame. The composition, colors and subject come from your image, so the prompt only has to explain what should move and how. Use it when the look is already decided and you want the picture to come alive without drifting away from it.

First and last frame

Give the generator both ends of the shot: an opening image and a closing image. Kling 4.0 works out the motion in between, which makes this mode useful for transformations, before-and-after reveals, product turns and transitions that have to land on a specific final picture.

How to make a video with Kling 4.0

A good Kling 4.0 clip usually comes out of a short loop: set up, generate, look closely, and change one thing at a time.

  1. 1Choose a mode. Use text to video for a new idea, image to video when you already have the look, or first and last frame when the ending matters as much as the beginning.
  2. 2Add your input. Upload a sharp, well-lit image if the mode needs one, then write a prompt that names the subject, the main action, the camera move and the lighting.
  3. 3Set the duration, resolution and aspect ratio. Check the estimated credits next to the settings and press Generate. You need to be signed in to start a generation.
  4. 4Review the clip in the player. If the motion is off, adjust the prompt; if the framing is wrong, change the image or the aspect ratio. Finished clips are saved to your library, where you can play and download them later.

Writing prompts that hold up in motion

A video prompt works more like a short note to a camera operator than a caption. The model has to decide what moves, how fast it moves and where the camera goes, so the more concrete those choices are, the more predictable the clip becomes.

One subject, one clear action

Name the main subject and give it a single action with a beginning and an end, such as a dancer turning to face the camera or steam rising from a cup. Several competing actions squeezed into one short clip tend to blur together.

Tell the camera what to do

Say how the shot is framed and how the camera moves: a slow push in, a gentle orbit, a handheld follow or a locked-off wide shot. If you leave the camera out of the prompt, the model picks a move for you.

Describe light and atmosphere

Time of day, light direction, weather and mood carry much of the look. Golden-hour side light, soft overcast, neon reflected on wet pavement: a few precise words here do more than a long list of adjectives.

Let the image do the heavy lifting

When you start from a photo, don't describe the whole scene again. Spend the prompt on motion and camera, and repeat only the details that must not change, such as a logo, an outfit or a face.

Example prompt
A ceramic coffee cup on a wooden café table, morning light from a window on the left, steam curling upward. The camera slowly pushes in and settles on the rim of the cup. Warm, quiet mood.

What each setting changes

The controls under the prompt shape both the result and the cost. They are read directly from the Kling 4.0 setup on this page, so you only see options that actually work.

Duration

Longer clips give an action more room to unfold, and they also use more credits. A good habit is to test the motion with a short clip first, then render the longer version once the prompt is right.

Resolution

The resolution menu sets the output quality. Use the lighter option for drafts and quick comparisons, and switch to a sharper one for the version you plan to publish. The difference shows most in fine textures, hair, small text and fast movement.

Aspect ratio

Choose vertical for short videos watched on a phone, widescreen for websites, presentations and ads that play on larger screens, and square for product listings and feeds where the clip sits in a grid.

Estimated credits

The estimate changes whenever you adjust the duration, resolution or mode, so you know the cost before you generate. If a task fails, its credits are refunded to your balance automatically.

What people make with it

Short, controlled shots are where Kling 4.0 earns its keep. These are the jobs it handles well.

Product videos

Turn a packshot into a slow reveal, a close-up of the materials or a turn that shows the product from a new angle, ready for a landing page or a store listing.

Character and portrait scenes

Bring a portrait or a character design to life with a glance, a smile, wind in the hair or a step toward the camera, while the face and outfit stay recognizable.

Story beats and storyboards

Sketch a sequence shot by shot, use first and last frames to connect key moments, and show a client or your team how a scene will move before a full production.

Social clips and ads

Make attention-grabbing openers, looping backgrounds and quick variations of one idea in different aspect ratios, so every placement gets a version that fits.

Questions about using the generator

How do I make a video with Kling 4.0?

Pick a mode in the generator at the top of this page, write a prompt and, if the mode needs one, upload an image. Set the duration, resolution and aspect ratio, check the estimated credits and press Generate. The finished clip plays in the result panel and is saved to your library.

Can I turn a photo into a video?

Yes. Choose image to video and upload a JPG, PNG, WebP or GIF as the first frame. Kling 4.0 keeps the composition of your photo and animates it according to your prompt, so describe the movement and the camera rather than the whole scene.

What is the first and last frame mode for?

It lets you decide where a shot starts and where it ends. Upload two images, describe the motion that should connect them, and the model fills in everything in between. It works well for transformations, reveals and transitions that must finish on a specific picture.

How many credits does one clip use?

It depends on the length and resolution you choose. The estimate is shown next to the settings before you generate, and credits are only deducted when a generation starts. If the generation fails, they return to your balance automatically. You can top up on the pricing page.

Why doesn't my video match the prompt?

Most mismatches come from prompts that ask for too much at once. Keep one main action per clip, state the camera move explicitly, and avoid contradictions such as a static camera that also orbits. When you start from an image, make sure the prompt doesn't describe a different scene from the one in the picture.

Where can I find and download my videos?

Every finished clip is saved to your library while you are signed in. Open the library from the sidebar to watch earlier results, download them, or reuse a prompt as the starting point for a new version.
