A precise curve editor that you own
Looking for a Motion Studio alternative for Premiere Pro? EaseFlow gives you a real graph editor right inside Premiere: drag the handles, type four numbers or paste a cubic-bezier, then press Apply.
Every frame between your two keyframes follows the curve you built. EaseFlow runs on Mac and Windows and is yours for a one-time $24.99 (Standard) or $34.99 (Pro), with free updates for life.
Watch the intro
Shape it by hand, down to the decimal
The EaseFlow panel opens with the graph on top and the curve's four numbers right below it. Change one and the other follows, so you can work by eye or by value.

- Drag with control. Hold Shift to snap a handle and Alt to mirror it. Every change is previewed live.
- Overshoot on purpose. Pull a handle past the edge of the box and the move goes slightly too far before it settles.
- See what's already there. A faint second curve shows the easing already on your keyframes, so you always know your starting point.
- Choose the end you ease. Out, In & Out or In, plus property chips to leave Position, Scale, Rotation or Opacity out.
Bring curves from anywhere
Found the perfect ease on a website, in a design file or in a developer's CSS? Copy it and paste it under the graph. EaseFlow understands four kinds of input:
- A cubic-bezier(). Straight from a CSS transition.
- A cubic-bezier.com link. The whole URL works.
- Four numbers. For example 0.34, 1.56, 0.64, 1.
- A spring. Written as spring(damping, frequency).

Your library, and your team's
Press + to save a curve as a preset, star the ones you reach for, and keep them in your own library. Export the library as a .json file and a teammate can import it, so every editor on a project eases with the same curves.
Standard includes the Default pack of 25 classic curves. Pro adds 47 more across the Essentials, Apple and Creator Pro libraries, plus every pack we add later.
Step 1: Install and dock the panel
Pick a version on the EaseFlow page. Your license key and download links arrive by email right after checkout, and the guided installer sets up the app and the Premiere Pro plugin. EaseFlow works with Premiere Pro 2021 to 2026.
Open the panel and dock it beside Effect Controls, where your keyframes already live.
Step 2: Drag, type or paste a curve
Start from a preset, then refine it. Drag a handle in the graph, edit the four numbers, or paste a value you copied. The preview shows the motion before anything touches your clip.

Step 3: Save it and press Apply
Save the curve with + so it is one click away next time. Then put the playhead on your keyframes and press Apply. EaseFlow eases the keyframes at or nearest the playhead, on every selected clip at once.
It works on any property Premiere animates with a number or a point: Position, Scale, Rotation, Anchor Point, Opacity and effect parameters, on video and audio. If you want to see the manual way first, our guide to easing keyframes in Premiere Pro covers it.
Step 4: Share the library
Use Export to save your library and send the file to your team. They choose Import Library, and your house curves show up in their panel, ready to apply. Our EaseFlow guide covers every panel option in detail.
FAQ
What is the best Motion Studio alternative for Premiere Pro?
EaseFlow. It has a graph editor with snapping, accepts pasted cubic-bezier and spring values, saves your own libraries and applies the curve in one click, for a one-time price.
Can I paste a CSS cubic-bezier into Premiere Pro?
Yes, with EaseFlow. Paste a cubic-bezier(), a cubic-bezier.com link or four numbers under the graph, then press Apply or save it as a preset.
