PremierCurve · Free Easing / Bezier Curve Editor · CEP
Premiere Pro's built-in "Ease In / Ease Out" is stuck on a single keyframe — you can't enter a cubic-bezier value. PremierCurve fills that gap: 31 ready bezier presets and a custom keyframe easing curve you draw on a square graph-paper. Free, no subscription.
In Premiere Pro you right-click a keyframe and pick "Ease In"; the result is the same fixed, unadjustable smoothing every time. You can't control how sharply it starts or how softly it ends — because Premiere gives you no graph editor or cubic-bezier input. This tool, present in After Effects, has been missing for Premiere users for years. PremierCurve adds exactly that.
Built-in easing is a single button — you can't change the curve shape.
Premiere has no surface to draw a bezier curve by hand.
31 presets + graph-paper editor = full control, in seconds.
From Sine to Elastic, Back to Bounce — every classic easing family used in motion design, ready to go. Select a keyframe, click a preset; the curve applies instantly. See them all here before downloading.
When presets aren't enough, the square graph-paper editor steps in: drag the two control handles to build exactly the cubic-bezier curve you want. Hard in + soft out, overshoot, a sharp stop — all in your hands. Save a curve you use often and recall it like a preset in your next project.

Premiere's built-in "Ease In / Ease Out" is limited to a single keyframe and won't let you enter a cubic-bezier value. PremierCurve lets you draw the curve by hand on a square graph-paper or pick one of 31 ready presets; the resulting easing is applied to the selected keyframes.

PremierCurve is a CEP extension and runs on Premiere Pro CC 2019 and later, on Windows and macOS. Even though Premiere 2025/2026 moved to UXP, CEP extensions can still be installed via .zxp; follow the steps in the "Install" section.
All three produce easing. OpenCurve is free and open-source but has no corporate page or docs. Easify is powerful but paid (~$35+) and its preset library sits behind a paywall. PremierCurve is free and offers 31 presets plus a visual custom-curve editor on a square graph-paper.
Yes. You can save a custom curve you use often and recall it like a preset — building an easing library specific to a brand or motion language.
Yes, both. Because it is CEP-based, it installs the same way on every desktop platform Premiere Pro runs on (Windows 10/11 and macOS).
PremierCurve, as the name suggests, is designed for Premiere Pro — it fills the visual keyframe easing editor that Premiere lacks. After Effects already has a powerful graph editor.
