# How AI video generation works on PornX

> Understand how PornX video generation works, including image-to-video, text-to-video, enhanced video, and session-based project workflow.

Video generation takes an image and animates it, or generates a clip directly from a text prompt. The primary path is image-first: generate a strong first frame in the image generator, then animate it.

## Two paths to video

**Image-to-Video (recommended)**
Generate an image, then animate it. This gives you control over the first frame before
committing to a video generation. Maximum duration is five seconds.

**Text-to-Video**
Write a prompt and generate a clip directly, without a first frame. Faster to start, but less control over the exact composition and character details.

## The generation loop

<Steps>
  <Step title="Generate a first frame">
    Use the image generator with the Realism model. Compose the shot carefully — camera angle, character position, and lighting in the first frame carry through to the video. See [Workflow](/video-generation/workflow).
  </Step>

  <Step title="Open a video session">
    Start a new Session in the video generator. Sessions keep your generations grouped so you can manage multiple concepts separately. See [Sessions](/video-generation/sessions).
  </Step>

  <Step title="Select your path">
    Choose Image-to-Video to animate your first frame, or Text-to-Video to generate from a prompt directly.
  </Step>

  <Step title="Write a motion prompt">
    Describe the movement and action you want, not just the scene. See [Video Prompting](/video-generation/video-prompting).
  </Step>

  <Step title="Set resolution and generate">
    Pick a resolution that matches your first frame. Click **Generate** and wait for the clip to render.
  </Step>
</Steps>

## Token cost

Video generation uses tokens. Enhanced Video uses additional tokens. See [/premium](/premium) for current rates.
