# Mixer App

Customize layouts, positions, and assets in VDO.Ninja, with remote control to change the layouts dynamically. This is very efficient and low on resources compared to other methods.

The Mixer App is an alternative to the director's control center of VDO.Ninja. It gives you the full power to customize scenes, layouts and positions of the video feeds dynamically.

For audio-only OBS scenes, custom guest mixes, OBS playback returns, Meshcast show audio, and private talk, see [Room audio, OBS, Meshcast, and private talk](/guides/room-audio-obs-meshcast-and-private-talk.md). The guide separates what guests hear from what the broadcast hears and includes options for both Mixer and Director's Room users.

Recent layout versions also support per-slot crop controls (`top/right/bottom/left`) that persist in layout data and render using `clip-path`.

There are currently 3 versions of the Mixer App. The newest version with all the current updates is Alpha.

There is a YouTube video from Steve (December 2021) about the Mixer App. It's slightly out of date though.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.vdo.ninja/steves-helper-apps/mixer-app.md?ask=<question>&goal=<user_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.
