Frame-by-frame palette mapping
Richard Rosenman’s Palette Mapper is a free plug-in for Adobe After Effects. It extracts colour information from a sequence frame by frame and renders the result as vertical lines, creating a compact view of how a film’s palette changes over time.
Bit depth and output limits
The plug-in processes 8-bpc and 16-bpc projects. A 32-bpc source is converted to 16 bpc. Sequences of arbitrary duration can be mapped to an image up to 30,000 pixels wide, matching the stated internal After Effects limit.

Installation and compatibility
Installation uses the standard After Effects plug-ins folder for the AEX file. The original release supported 64-bit Windows 7 or later and After Effects CS6 or later.
Test the plug-in’s bit-depth conversion, output dimensions and compatibility on copies of production material before adopting it.
