A 3GP file represents a streamlined video format from the 3rd Generation Partnership Project built for early 3G phones with tiny storage, slow processors, and weak batteries, functioning as a simplified MP4 container that stores compressed video (often H.

A frequent issue people see with 3GP files now is silent audio, and this almost always comes from AMR being unsupported by newer media software instead of the file being broken, leading players and browsers to decode the video but ignore the audio because AMR falls outside standard workflows, while editors typically require AAC or PCM and may refuse AMR outright, giving the impression that the audio vanished.
Another format, 3G2, often has even worse compatibility issues today, as its CDMA background means it carries audio codecs like EVRC, QCELP, or SMV that nearly no modern player supports, resulting in video-only playback until a converter decodes the old telecom audio and re-encodes it into AAC, confirming the file’s original use of a now-obsolete voice codec.
3GP and 3G2 aren’t radically separate formats like AVI and MKV but are close relatives sharing the ISO Base Media File Format foundation with MP4, so a parser sees almost identical structures and relies mainly on subtle ftyp brand cues such as 3gp6 or 3g2a, which many tools interpret loosely.
To put it briefly, 3GP and 3G2 belonged to an outdated era of mobile technology where compatibility meant running on early phones, not today’s systems, so silent audio or playback failures arise from legacy codecs, and the straightforward remedy is converting the audio into a supported format while keeping the video as is.
