I have a project checked into a source code repository and the footage files (mostly WAVs) are a certain size. When I open my After Effects project that contains them, the file size is changing (by about a kilobyte)!
Our footage files are on network-attached storage and many render machines open and modify this template project (and save a customized version to a unique file elsewhere). This file size change causes unnecessary NFS traffic and repository bloat.
Why is After Effects doing this and how do I stop it?
