# Universal Crossfade

The Universal Crossfade widgets can be found in the far left part of the Timeline Editor window section.

This function allows you to execute a crossfade from any point to another in the Timeline. If the Playhead jumps from any location to another on the Timeline, a smooth transition will occur.&#x20;

{% hint style="info" %}
The number and type of Clips (Media, FX, Input Device) being read at each location does not matter; the system will still execute a smooth crossfade between the two states.
{% endhint %}

## Set Universal Crossfade Duration

{% hint style="warning" %}

## 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.tachyon.video/user-guide/4.-programming-a-show/timeline-editor/universal-crossfade.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.
