About SMP Pro

SMP Pro is a property selection and batch‑editing tool for After Effects versions 2021 through 2026. It scans all layers or only selected layers, then narrows results using filters for exact values, expression presence, or animation state (animated or static). Selected properties can be edited together: you can type an expression and inject it into every property at once, or remove keyframes and expressions in a single operation. The Limit Results option caps the number of matches to help avoid freezing in very large projects. Typical uses include deleting stray keyframes, updating repeated color values, or applying a loopOut() expression to many rotation properties in one click. SMP Pro is offered as a free download.
