What is an M2TS file?
The M2TS (MPEG-2 Transport Stream) file format is a high-definition digital video container format used for multiplexing audio, video, and other streams, primarily associated with the Blu-ray Disc Audio-Video (BDAV) container format. It is based on the MPEG-2 transport stream container and is used for structuring content on Blu-ray Discs and AVCHD camcorders (Sony/Panasonic). M2TS files typically contain video compressed using H.264/MPEG-4 AVC, VC-1, or MPEG-2 codecs, allowing for variable bitrates and high-resolution playback.
How to open an M2TS file
Windows usually supports M2TS playback natively through the Movies & TV app if the necessary codec extensions are installed. However, for reliable playback across macOS and Windows without codec errors, VLC Media Player is the standard solution as it natively handles the MPEG-2 TS encapsulation. High-end video editors like DaVinci Resolve and Adobe Premiere Pro also support M2TS import for editing camcorder footage.

What is a FLAC file?
The Free Lossless Audio Codec (FLAC) is an open-source audio coding format developed by the Xiph.Org Foundation that compresses digital audio without any loss of data (bit-perfect preservation). It employs linear prediction and Rice coding (Golomb-Rice) rather than the perceptual psychoacoustic modeling used in MP3 or AAC. The format structure consists of the 'fLaC' stream marker, metadata blocks (Streaminfo, Vorbis comments for tags, Seekpoints), and audio frames, typically achieving compression ratios of 50-70% compared to raw PCM WAV files.
How to open a FLAC file
FLAC enjoys extensive native support on modern platforms, including Windows 10/11, Android, and macOS (starting with macOS High Sierra). For older systems or advanced playback control, software such as Foobar2000 (Windows) or Vox (macOS) is recommended. The VLC media player is a universal solution for all operating systems, handling FLAC streams and associated metadata seamlessly.
