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.

Example: The Matrix (1999) mapped to a 1280-pixel-wide image

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.
