Because MTS supports H.264 just like 3GP does, the video stream can be carried across without a quality-costing re-encode.
Embedded subtitle tracks will be lost. 3GP can carry them inside the file; MTS has no place to store them, so export them separately first if you need them.
At 1080p, 3GP typically runs around 1.1 Mbps while MTS sits near 23 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 2006, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts 3GP video, stored in the 3GPP container since 2001, into MTS, which uses AVCHD and dates from 2006. The codecs each container accepts decide whether the picture has to be re-encoded.
3GP comes from 3GPP and dates to 2001. It usually holds H.263, MPEG-4 Part 2, or H.264 video with AMR-NB, AMR-WB, or AAC-LC sound, and those streams set the ceiling for anything converted out of it.
MTS comes from Sony / Panasonic and dates to 2006. It holds H.264 video alongside AC-3 or LPCM audio, and every major platform needs a media player such as VLC to open it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
