Start with words rather than an upload. Describe an adult character, a setting, one action and the camera movement. Kling 4.0 creates a new clip with synchronized audio. A short first attempt helps you check the composition before committing to a longer scene. Add dialogue or room ambience to the prompt when sound matters.

Text to Video is the only Kling 4.0 workflow here that needs nothing but a prompt. Without a picture to copy, the model invents every detail you leave out: age cues, clothing, the room, the light and the lens. Name the adult subject clearly, place them in one location and give them a single action that fits the length you choose.
Sound is generated together with the picture, so the prompt doubles as your sound brief. Say whether anyone speaks, what the room sounds like and whether music belongs in the scene. Keep dialogue to a short line and say who delivers it; a long script squeezed into five seconds tends to feel rushed.
A new task starts at 5 seconds, 720p and 16:9. That default is a sensible test: it shows whether the composition, subject and sound work before you spend more. Afterwards you can pick any length from 3 to 30 seconds, move to 1080p, or switch to 9:16 for a phone screen, 1:1 for a square post or 21:9 for a wide cinematic frame. There is no 4K option.
Generating requires a signed-in account and Peppers from a one-time pack. The quote updates as you change duration and resolution, so a 30-second 1080p clip costs more than the default test. When you submit, the quoted amount is reserved; it is charged once the finished clip is saved, or released if the task is confirmed as failed or timed out.
