What It Does
Keyframe Velocity Changer gives you control over incoming and outgoing velocity for multiple keyframes across multiple layers simultaneously. It replicates Adobe’s built-in Keyframe Velocity window (Cmd/Ctrl+Shift+K) but solves its core limitation: the default tool struggles when you select many keyframes at once, often producing inconsistent results. This script provides a dockable panel that handles bulk velocity changes reliably, whether you’re working with 2D position, 3D transforms, or any animated property.
Key Features
Multi-layer editing. Select keyframes across different layers and adjust their velocity settings together. Incoming speed, outgoing speed, and influence values all update uniformly.
Preset system. Save velocity configurations you use often (like ease-in curves for titles or snappy cuts for kinetic text). Delete outdated presets as your style evolves.
Preset export. Export your saved presets to a .json file. Keep the file in Dropbox or another synced folder to use the same velocity settings across multiple machines.
Slider controls. The dockable interface includes min/max values and supports float inputs for precise adjustments.
Lock continuous. A button syncs in/out speeds when you need symmetrical easing.
Who It’s For
Motion designers who animate frequently across multiple layers will find this most useful. If you’re doing character rigging, text animation, or kinetic typography where consistent timing matters, bulk velocity editing speeds up iteration. It’s particularly helpful when you need to apply the same easing curve to dozens of keyframes without manually adjusting each one.
Pricing
Keyframe Velocity Changer uses a pay-what-you-want model with a suggested minimum of $9.99. Individual users can choose their price; teams and businesses are expected to pay the suggested amount for a valid license. The script works in After Effects CC 2015, CC 2014, CC, CS6, and CS5.5.
