What It Does
Calc AE is a dockable calculator that performs timecode math inside After Effects. Instead of opening a separate calculator or doing mental arithmetic, you can add, subtract, and manipulate timecode values using your comp’s actual framerate. The panel automatically updates when you switch compositions, ensuring calculations stay accurate across different framerates.
The calculator displays results in both timecode and frame count, so you can work in whichever format makes sense for your task.
Key Features
Timecode Assist Tools. Instead of typing timecode manually, these shortcuts insert values directly from your timeline:
Layer(s) pulls the duration from the first inpoint to last outpoint of selected layers. Hold Ctrl for just the earliest inpoint, or Alt for the last outpoint.
Keyframes grabs the span between your first and last selected keyframes. Ctrl gives you the time of the earliest keyframe, Alt the latest.
CTI (Current Time Indicator) inserts the playhead position. Ctrl calculates the duration from CTI to the earliest layer inpoint, Alt to the last outpoint.
Markers measures the distance between the first and last marker on selected layers (or comp markers if nothing is selected). Ctrl and Alt modifiers grab individual marker times.
CTI Markers finds the markers immediately before and after the playhead, then inserts their duration.
Work Area uses the comp’s work area duration, with Ctrl/Alt shortcuts for start and end times.
Insert Value pastes the current calculation result. Ctrl recalls a previously saved value, Alt stores the current result for later.
Go to Time moves the playhead to the calculated timecode. Ctrl/Alt move it left or right by the number of frames in the result.
The panel includes toggleable math operation buttons (addition, subtraction, etc.) that can be shown or hidden via a Shift+Calculate shortcut.
Who It’s For
Useful for editors working with precise timing, especially when syncing to markers, adjusting layer durations, or spacing keyframes at exact intervals. If you frequently need to know “how long is this section” or “where should this end if it starts here,” this saves the manual math.
