Kling 4.0 Image to Video Generator: the short answer
Kling 4.0 animates a still image: the video starts on your picture and moves it the way you describe. On Vuddex you upload a photo or illustration, write the motion ("she turns and smiles, camera pushes in"), choose 3, 5, 10, 15 or 30 seconds, and get an MP4 in a few minutes in your browser, with no app. A clip starts at 95 credits (about $2.37–$3.16), and failed clips are refunded.

Which image works best with Kling 4.0?
The image is the first frame, so its quality sets the ceiling:
- Sharp and well lit: blur and noise get worse once things move
- A clear subject: one person, animal or object the motion can follow
- Room to move: leave some space around the subject if it should walk, turn or the camera should pull back
- The aspect ratio you want: a vertical photo makes a vertical video
Use only photos of yourself or of people who agreed; photos of children and public figures are not allowed.
How do I write the motion prompt for Kling 4.0?
Do not describe what is already in the picture — the model can see it. Describe what changes: "the woman laughs and brushes hair from her face, light wind, camera slowly pushes in". One main movement plus one camera move works best. Ask for small, natural motion when the face must stay recognisable; big turns and fast action change the face more.
What can I make with Kling 4.0?
Bring old family photos to life, animate a character or an illustration, turn a product photo into a short ad, make a portrait blink and smile, add drifting clouds or waves to a landscape, or animate an image you made with an AI image generator. The first frame stays yours, so the result looks like your picture, not a random scene.
How long are Kling 4.0 videos, and what do they cost?
You pick the length before you generate: 3, 5, 10, 15 or 30 seconds. Price depends on length and resolution and starts at 95 credits, about $2.37–$3.16 depending on the plan or pack you buy. The exact cost is shown on the Generate button before you spend anything.
If a clip fails or is blocked by the safety check, the credits go back to your balance automatically.
