What It Does
KeyTweak solves a specific problem: when you have 100 keyframes on a mask or tracked property and need to fix an error, you normally adjust each keyframe individually. KeyTweak propagates changes from one or two edited keyframes across the entire animation, so the correction applies everywhere automatically.
This works on any keyframed property, not just masks. Useful for correcting a drifting track, refining layer position over time, or adjusting mask paths after using the built-in Mask Tracker.
Key Features
Automatic propagation. Edit one or two keyframes and the plugin applies the change across all keyframes in that property.
Works on any property. Not limited to mask paths. Use it on position, rotation, scale, effect points, corner pins, or any other keyframed parameter.
Multiple modes. Choose how the change propagates: Work Area, Constant, or Local mode. Local mode works specifically for 2D properties like corner pin points.
Wide compatibility. Supports After Effects CS3 through 2026, covering nearly two decades of software versions.
Who It’s For
Rotoscope artists who track masks and need to correct drift. Motion designers refining keyframed layer movement. Anyone working with large keyframe sets who wants to avoid tedious manual adjustments frame by frame.
