# Video Overlays

Video overlay (AVI) files can be saved after analysis of a movement trial is completed, and can be saved from within Theia3D or Theia3D Batch. These videos show any [display options](/axiom-v2025/theia3d-documentation/theia3d-dropdown-menus/display-menu.md) of the tracking produced by Theia overlaid on the original video files, which can be useful for Quality Assurance or demonstration purposes.

To save video overlays from Theia3D, use the Save Video Overlay button in the sidebar or under the File dropdown menu.

To save video overlays from Theia3D Batch, select Save Videos and any desired display options and camera views to be saved, prior to running the analysis.

# Agent Instructions
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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.theiamarkerless.com/axiom-v2025/theia3d-documentation/data-formats/video-overlays.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
