# Video models

> Six major video generation families — Google Veo, Kling, Sora, LTX, Seedance, and utility models — covering T2V, I2V, lip sync, and upscaling, all priced per second of output.

Video credits scale with **output duration × model rate**, plus resolution and audio multipliers. Studio displays the estimated cost before you confirm every generation.

<Tip>
  MCP video tools accept `durationSeconds` (typically 2–12 seconds). Studio shows the cost estimate before you run — adjust duration or model tier to control spend.

## Which video model should I use?

<Tabs>
  <Tab title="Google Veo">
    **High-quality text-to-video and image-to-video with built-in audio support.**

    | Model        | Notes                                      |
    | ------------ | ------------------------------------------ |
    | Veo 3.1      | Flagship; full audio support               |
    | Veo 3.1 Fast | Faster generation at the same quality tier |
    | Veo 3.1 Lite | Efficient variant; lower per-second cost   |
    | Veo 3        | Previous generation; solid quality         |

    Best for: cinematic scenes, complex motion, and productions that need built-in audio synced to video.
  </Tab>

  <Tab title="Kling">
    **Versatile motion and general video generation.**

    | Model    | Notes                                    |
    | -------- | ---------------------------------------- |
    | Kling O3 | Latest generation; strong motion control |
    | Kling V3 | General-purpose video                    |

    Best for: character animation, motion-heavy clips, and mid-tier budget productions.
  </Tab>

  <Tab title="OpenAI / LTX / ByteDance">
    Three distinct families covering cinematic, efficient, and social-ready outputs.

    | Model             | Provider   | Notes                                         |
    | ----------------- | ---------- | --------------------------------------------- |
    | Sora 2            | OpenAI     | Cinematic quality; strong scene coherence     |
    | LTX 2.3           | Lightricks | Efficient generation; good for fast iteration |
    | Seedance 2.0      | ByteDance  | Social-ready motion; fast turnaround          |
    | Seedance 2.0 Fast | ByteDance  | Fastest variant; lower cost per second        |
  </Tab>

  <Tab title="Utilities & Specialized">
    Specialized models for editing, transformation, and lip sync.

    | Model             | Notes                                                         |
    | ----------------- | ------------------------------------------------------------- |
    | Happy Horse       | Distinctive motion style                                      |
    | Gemini Omni Flash | Multimodal video generation tasks                             |
    | Fabric            | Lip sync — matches audio track to existing talking-head video |

    <Note>
      Utility transformations (inpaint, background removal, upscale, extend) are available for post-processing existing clips and have fixed-ish action costs rather than per-second pricing.
