Convert MTS to FLAC - Complete Guide

Converting MTS to FLAC turns a video file into an audio file. MTS is a video format. AVCHD video. FLAC is a lossless audio format used for high-quality music archives without the large size of raw audio. Below is exactly what changes when you convert MTS to FLAC, what is preserved, and when FLAC is — or isn't — the right target format.

What changes when you convert MTS to FLAC

  • FLAC is lossless, so no new compression artifacts are introduced. It cannot restore detail already discarded by MTS.
  • This is a video-to-audio conversion, so the file moves into a different type of workflow. The converter maps the MTS content into a usable FLAC result for the formats involved.
  • Expect a smaller output file: FLAC is typically more space-efficient than MTS for the same content.
