What changes when you convert MTS to AVI
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.
