About Marker Conductor
Marker Conductor is an After Effects utility that lets users place markers using a Time tab and a BPM tab, each with a Duration field. A Settings tab provides a custom marker comment template accepting {count}, {time}, {frame}, {bpm}, and {beat} tokens, and supports composition‑time comment options such as Time(Comp) and Time+Unit(Comp). BPM markers insert a cue point on the first measure and allow an additional start position; beat numerator and denominator values are supported up to 16. The plugin is compatible with After Effects versions CC 2017 through 2026 and runs on macOS Catalina. It is listed as free in this catalog.
