A 3GP file is fundamentally an old mobile video format developed by the 3rd Generation Partnership Project for early 3G phones, built for a time when devices had minimal storage, slow processors, and weak batteries, making it a simplified container similar to MP4 that focused on tiny file sizes and reliable playback rather than quality, storing compressed video and audio—often H.263 or basic H.264 for video and AMR for voice-centered audio—which results in narrow speech and missing background details today.
One of the biggest challenges with 3GP files now is silent playback, which nearly always traces back to AMR being unsupported rather than the file being defective; modern players and browsers avoid AMR because it complicates licensing or doesn’t fit typical media pipelines, and editors—favoring AAC or PCM—often refuse AMR entirely, making it look like the audio was removed even though it was intentionally ignored.

A related format, 3G2, tends to behave with greater issues on modern systems, since unlike 3GP—which came from GSM networks—3G2 was built for CDMA networks and usually contains codecs like EVRC, QCELP, or SMV that are rarely accepted today, causing video to play without audio until conversion tools decode these telecom codecs and re-encode them into AAC, confirming that the original file relied on outdated voice technology.
3GP and 3G2 are not entirely unrelated formats like AVI versus MKV; they share the same ISO Base Media File Format origins as MP4, meaning their internal boxes for timing, tracks, codecs, and metadata look almost identical, and the main way they differ is through subtle ftyp brand tags like 3gp6 or 3g2b that many programs barely acknowledge.
In summary, 3GP and 3G2 came from a vastly different tech landscape where guaranteeing playback on early phones mattered more than fitting modern pipelines, meaning silent audio and inconsistent playback stem from obsolete codecs, not corruption, and the clear solution is to re-encode the audio into a current codec while leaving the video untouched to bring the file up to modern compatibility.
