What changes when you convert MTS to FLV
Because FLV supports H.264 just like MTS does, the video stream can be carried across without a quality-costing re-encode.
Only one audio track will be kept. MTS can hold several, for example alternate languages, but FLV supports a single track.
FLV is built for streaming and progressive download, so the result starts playing before it has fully loaded, which the source format does not do well.
At 1080p, MTS typically runs around 23 Mbps while FLV sits near 4.5 Mbps, which is the main driver of the size difference you will see.
Any chapters in the source disappear: FLV does not store chapter markers.
