Leopard Technical Q&As: QuickTime
Image importers and exporters manage the import and export of graphic images, such as JPEG, TIFF, Photoshop, and PNG. Movie data exchange components support the import and export of other multimedia formats, such as AIFF, WAVE, AVI, MPEG-1, MIDI, MPEG-4, 3GPP, MP3, MPEG-2, H.263, and OpenDML. QuickTime can open any format file for which it has an importer and create any for which it has an exporter.
