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 an AVI file?
Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows technology. It adheres to the Resource Interchange File Format (RIFF) specification, storing audio and video data in tagged chunks (specifically 'movi' lists) to allow synchronous playback. While widely compatible, the legacy AVI architecture lacks native support for modern features found in MP4 or MKV, such as variable frame rates (VFR), B-frames, and sophisticated chapter markers. It typically utilizes codecs like DivX, Xvid, or MJPEG.
How to open an AVI file
AVI files enjoy broad compatibility on Windows via Windows Media Player. However, because AVI is a container that can hold various codecs (e.g., DivX, Xvid), playback may fail if the specific codec is missing. macOS users can view AVI files using QuickTime Player if the content is MJPEG, but third-party players are often required for other codecs. VLC media player and MPC-HC are standard recommendations for handling the vast array of codecs potentially encapsulated within an AVI file.
