# Keyframes

Gyroflow comes with the ability to keyframe most parameters in order to achieve any look you want.

Most parameters in Gyroflow can be keyframed - meaning their value can be changed in different parts of the video (i.e. you can use a different smoothness at the start of the video, compared to the end).

## How to use?

### Enabling keyframes

Keyframes can be enabled by right-clicking on the slider and choosing **Enable keyframing.**

Then, go to a time in the video when you want the value to be different and just change the slider value. This will create a keyframe on the timeline chart.

### Keyframe easing

You can right-click the keyframe point to enable or disable easing (it's enabled by default).

### Removing/disabling keyframes

You can right-click the keyframe point to delete it, or to disable all keyframing for a slider, right-click on the slider and uncheck **Enable keyframing** - this will clear all keyframes on that slider.

## Keyframeable parameters

* Smoothness
* FOV
* Zooming speed
* Zooming center offset
* Horizon lock amount / roll correction
* Lens correction strength
* Max smoothness
* Max smoothness at high velocity
* Pitch/Roll/Yaw smoothness
* Video rotation
* Background margin / feather
* Video speed

## Example

{% embed url="<https://gyroflow.xyz/demo/docs/?v=keyframing>" %}

## Caveat

When keyframing zooming speed and the speed changes are significant, make sure to switch the zooming algorithm to **Envelope follower.**

There is a known bug with the **Gaussian filter** algorithm which may lead to black borders in view when keyframing zooming speed.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.gyroflow.xyz/app/advanced-usage/keyframes.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.
