# Keyrails

> Clean ease curves without nudging a handle off-value.

## Information

Stop fighting keyframes in Premiere. Keyrails lets you drag keyframe handles perfectly horizontal in Premiere Pro without changing the keyframe value, so you can shape smooth ease-in / ease-out curves instantly — no After Effects detour required.

### The problem

When you adjust ease in / ease out keyframes in Premiere Pro, dragging the Bezier handle to shape the motion curve also nudges it up or down, which changes the keyframe's value and ruins the smooth motion. Handles drift while you try to drag them in a straight horizontal line, motion curves take several retries to get right, and you end up zooming in and eyeballing alignment just to keep the value the same.

### The solution

Keyrails lets you drag keyframe handles horizontally without changing the keyframe value. Hold your hotkey and the handle snaps to a locked rail, so you can shape easing curves smoothly and precisely without leaving the graph editor.
