About Control LMFX
Control LMFX is an After Effects panel designed to streamline workflow by consolidating frequent tasks into one location. It provides a Duplicate Compositions tool that copies timelines when Shift is held, an FPS Editor that adjusts frame rates of selected media or compositions based on the active composition with manual input and filtering, and Recolor Keyframes for text layer animation. The Sort Files feature adds keyword‑based sorting and an Unused Files group, while the FX Manager and Group Viewer give a clear effects list view. Palette Manager handles color palettes and lets you set a default label color for new null objects. Version 1.1.4, released June 1 2026, introduces the Shift‑based FPS editing, duplicate composition support, default null label color, and performance fixes for long sessions. The panel runs on After Effects 2022 through 2026.
