About MP4
MP4 (MPEG-4 Part 14) is a container format standardised by ISO. It usually holds H.264 or H.265 video with AAC audio, and it can also carry subtitles and chapter markers.
It is the most widely supported video format: phones, browsers, smart TVs and video sites all play it.
The video inside an MP4 is almost always compressed with a lossy codec, so every re-encode loses a little quality.

Why is my MP4 file so large? MP4 video is already compressed with H.264 or H.265, so a lower bitrate or resolution shrinks the file at the cost of some quality.
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 convert video to 3GP? Almost only for very old feature phones with tiny screens; any smartphone plays MP4 instead.
