Why we ask

Putting a real person into a video without their OK can break privacy and image-rights laws, and that responsibility is yours. We keep the time you confirmed with the request.

How to use the AI image generator

  1. Write the prompt

    Name the subject first, then the setting, the style, the light and any words that must appear.

  2. Add a reference (optional)

    One JPG, PNG or WebP image keeps a face, product or layout close to what you have.

  3. Pick model, ratio and resolution

    The credit cost updates as you change the model or the resolution.

  4. Create, then animate

    Download the picture, or send it straight to the video studio as the first frame.

Prompts that work in an AI image generator

  • Lead with the subject: "a ceramic coffee cup on a wooden table" beats "a cozy morning scene".
  • Say the camera: close-up, wide shot, top-down, 35 mm, shallow depth of field.
  • Name the light: soft window light, golden hour, studio softbox, neon at night.
  • Put exact text in quotes, for example a sign that reads "OPEN".
  • Choose the ratio for where it goes: 9:16 for stories, 16:9 for a video frame, 1:1 for a profile.

From AI image to AI video

A generated still makes a clean first frame. Press "Turn into a video", and the image opens in the video studio, where Seedance 2.5, Kling 3.0 and Wan 3.0 and the other models animate it. That is often cheaper than retrying a video until the first frame looks right.
