Part 1. What is the difference between *.m2ts and *.flac

In a nutshell, M2TS is a video format primarily used by Blu-ray discs, whereas FLAC is an extension used by the audio files.

To elaborate, M2TS stands for MPEG-2 Transport Stream and is a container that holds both video and audio information. The videos that M2TS contains have been encoded with either H.262 or compression method, and the audios are of Dolby Digital, DTS, or Linear PCM quality.

When talking about FLAC, the audio file is compressed using Free Lossless Audio Codec (FLAC). Although the audio information is compressed with an open-source codec, the FLAC files are comparatively large because of being lossless.
