PT3 to G4 conversion is the process of transforming files encoded in the PT3 format into the G4 format so they can be opened, edited, or used by software that requires G4. This conversion typically remaps PT3's container/encoding structures into G4's expected layout while preserving as much data and metadata as possible.
