Quality - 3gp King Youtube Extra

Background: 3GP’s technical and historical place 3GP (3GPP file format) is a simplified profile of the ISO Base Media File Format (the same family as MP4) designed for mobile phones and networks of the early 2000s. It was optimized for low bitrate video and audio streams, using codecs such as H.263, MPEG-4 Part 2, and later H.264 for video, and AMR or AAC for audio. The format’s raison d’être was to enable acceptable audiovisual experiences across unreliable cellular links and underpowered devices.
