# Interface

### **Change duration**

To change the duration, grab and move the handle that is positioned on the right side of the time ruler. Move to the right to extend the duration and to the left to shrink.

### **Zooming on the timeline**

You can zoom in and out on time periods to edit keys more precisely

Use the slider on the top of the ruler to zoom in and out.

### **Choose frames or seconds**

You can switch the ruler to visualize the time from frames to seconds. The timeline will play the same no matter what you choose—It's just a matter of how the ruler visualizes the time. By default it shows the time in increments of 24 frames per second.

When you record the animations in real-time or edit, visualization in seconds might be more convenient.

### Lock playing in camera cut

# 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://learn.tvori.co/tools/timeline/interface.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.
