aftereffects-version-check

A Python script to determine the After Effects Version used to save the project.

This script is rewritten and now actually calculates the project version instead of just comparing a HEX string in a data table.

After some more data analysis I finally understood how the project version is encoded in the project file. See the analysis below.

I have kept the JSON data for further analysis and to look up the year the software version was released.

How to run

py afx-version-check.py PROJECTFILE.aep

Examples

Under the folder aftereffects_projects there are some project files to test the script For example: py afx-version-check.py aftereffects_projects/2023_23-3-0_build53.aep

Analysis

Example: 17.0.2 (Win) (Build 26) (Structure is Major.Minor.Patch (OS) (Build) BETA )

At offset 36 in the project file we get a HEX string of 0B 08 16 1A

Bit 27-31 & 20-22 Major-Version is split up. MAJOR-A and MAJOR-B have to be merged.
