# Keyframes 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="" %} ## 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.
