# Output Controls

Before generating a video, Output Controls let you define the technical parameters of your output — how many videos to produce, how long they run, what resolution to render at, what dimensions to use, and whether to include audio.

Every setting directly affects the **credit cost** of your generation. The live credit counter updates in real time as you adjust any control — so you always know the exact cost before committing.

#### Output Controls at a Glance

| Control                       | What It Defines                                 | Credit Impact                  |
| ----------------------------- | ----------------------------------------------- | ------------------------------ |
| **Number of Generations**     | How many video variations to produce in one run | Multiplies total cost linearly |
| **Video Duration**            | Length of the generated video in seconds        | Shorter = fewer credits        |
| **Resolution & Quality**      | Visual fidelity — 720p, 1080p, or 4K            | Higher = more credits          |
| **Aspect Ratio & Dimensions** | Shape and framing of the video                  | No credit impact               |
| **Audio Generation**          | AI-generated audio (Seedance models only)       | Off = slightly lower           |

#### How Output Settings Affect Credits

Each output control contributes to the total credit cost of a generation. Adjusting model, resolution, duration, audio, or generation count changes the cost — visible in the live credit counter before you generate.

For a complete breakdown of how credits are calculated across all settings, see\
Understanding Credit Usage →.

#### Resetting Output Controls

The **Reset** option clears all current settings and inputs — selected model, uploaded images, prompt, keywords, duration, dimensions, and generation count. Use this when starting a completely new generation from scratch to avoid carrying over settings from a previous run.

#### What's in This Section

1. **Number of Generations →** How batch generation works, when to run multiple at once, and how generation count multiplies your credit cost.
2. **Duration, Resolution & Quality →** Supported durations, resolution options from 720p to 4K, per-model availability, and how both settings affect credits and output fidelity.
3. **Aspect Ratio, Dimensions & Audio →** Available dimension presets, platform recommendations, audio generation controls for Seedance models, and tips for matching output framing to reference images.
