About 3GP
3GP is a container format defined by the 3GPP for mobile phones. It is a simplified relative of MP4 that typically holds H.263 or H.264 video with AMR or AAC audio.
Videos recorded on older mobile phones, especially before smartphones.
3GP videos are usually low resolution and heavily compressed, and converting them cannot add detail.

Why is the video from my old phone so tiny and pixelated? 3GP was built for small low-resolution phone screens on slow mobile networks, so there is no detail in the file to recover — the source simply never had it.
About Opus
Opus is an open, royalty-free lossy audio codec standardised by the IETF in 2012 (RFC 6716). It handles both speech and music well, from very low to high bitrates.
Voice and video calls, WhatsApp voice messages, WebRTC, and the audio track of WebM videos.
Opus always decodes at 48 kHz, and some older players and devices do not support it.
Why convert voice recordings to Opus? It stays clear at very low bitrates, so calls and dictation shrink dramatically without becoming hard to understand.

- The soundtrack of the 3GP is re-encoded as Opus at the default settings, so it is close to the original but not bit-identical.
