Ka whakamahia e PNG te whakawhāititanga DEFLATE i runga i ngā raina tātari tātari, kia ora ai ia pikitia, tae atu ki tētahi kanikani ā-arawhiti 8-biti.

Kāore te 3GP kāwai e rokiroki i te EXIF-per-frame i te tikanga o tētahi pūwhitiwhiti, nā reira ka puta mai te PNG me te EXIF mokowā. Ka whakawātea e tātau i tētahi āpure 'creation_time' e tohu ana ki te rārangi pūtake o te rārangi wā kia taea ai e koe te whakarōpū anō i te pūhui mā te raupapa tātari.
