The video stream has to be fully re-encoded: MTS typically carries H.264, and AVI expects MPEG-4 Part 2. That means a real transcode, so allow for processing time and a small generational quality cost.
At 1080p, MTS typically runs around 23 Mbps while AVI sits near 7 Mbps, which is the main driver of the size difference you will see.
Any chapters in the source disappear: AVI does not store chapter markers.
This is an older container, introduced in 1992, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts MTS video, stored in the AVCHD container since 2006, into AVI, which uses RIFF AVI and dates from 1992. The codecs each container accepts decide whether the picture has to be re-encoded.
MTS comes from Sony / Panasonic and dates to 2006. It usually holds H.264 video with AC-3 or LPCM sound, and those streams set the ceiling for anything converted out of it.
AVI comes from Microsoft and dates to 1992. It holds MPEG-4 Part 2, DivX, or Xvid video alongside MP3, PCM, or AC-3 audio, and without installing anything it plays on Windows.
