# Camera Video Source
The Camera Video Source renders the scene from the perspective of a selected camera. This can either be a Camera object or a Camera Selector object. If no source is selected, the output of the current viewport is used.
The Camera Video Source renders the scene independently. To improve performance, the Framerate setting can be used to update the output only every second or third frame instead of rendering it on every frame.
Proceed as follows:
1. Create one or multiple Camera Objects and place them into your scene
2. Create a Camera-Selector Object (`Create > Scene > Camera Selector`)
3. Go to Settings > Video Sources...
4. Click on the "Add" Button and choose "Camera Video Source"
5. Once selected, pick the Camera-Selector object from the drop down
6. check Active
Now you can use this Video-Source on any Texture or Projector.
{% hint style="info" %}
When a Camera Selector is used as the source, it is exclusively linked to the Video Source and no longer controls the current viewport.
{% endhint %}
{% hint style="info" %}
If no Camera or Camera Selector is selected, the output of the current render viewport is used, including its current resolution. In this case, no additional frame needs to be rendered, which avoids unnecessary performance overhead.
{% endhint %}
### NDI Output
When the NDI Output option is enabled, Depence sends the rendered output directly via NDI. This allows you to use Depence content on real video walls, making it ideal for hybrid shows that combine physical and virtual elements.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.depence.com/depence-construction/depence-video-sources/camera-video-source.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
