Before you start

  • Use the current, complete source version
  • Mark the sections, steps, charts, or figures that deserve focus
  • Identify the terms, numbers, warnings, or wording that must remain

A focused path

Use the image as the visual anchor for the explanation

  1. 1

    Choose the image that carries the idea

    Use a product image, portrait, diagram, or visual reference that shows the subject the viewer needs to understand.

  2. 2

    Define what the image should explain

    Name the audience, the question to answer, and the relationship, detail, or process that should become clear.

  3. 3

    Build a clear visual sequence

    Use narration, labels, diagrams, and supporting scenes to guide the viewer from the image to the key takeaway.

Useful next step

What should the image do in the video?

Image to video can mean different jobs. Choose whether the image should carry an explanation, become a moving shot, or appear in a simple sequence.

  • 01

    Explain an image or diagram

    Use when the viewer needs to understand parts, labels, relationships, evidence, or a process shown by the image.

    KPainter uses the image as the source anchor, then adds narration, labels, diagrams, and supporting scenes around one clear question.

  • 02

    Animate a still image

    Use when the main outcome is motion, camera movement, atmosphere, or a short visual shot.

    Choose an image-to-video generation workflow when the image itself should move and a narrated explanation is not the primary goal.

  • 03

    Create a slideshow

    Use when several images only need to appear in order with simple captions, timing, or music.

    Use a slideshow or timeline editor for a direct sequence. Choose KPainter when those images need a new narration and explanatory structure.
