MPEG Transport System (MTS) is the file type that high-definition (HD) camcorders produce when they capture video and audio. Sony and Panasonic developed MTS, but Canon, JVC, and other camcorders also create MTS files. This file type is also compatible with Blu-ray, and another designation for MTS is Advanced Video Coding High Definition (AVCHD).

 

How to open an MTS file?

MTS is a standard and common file type for camcorders and Blu-ray. As such, simply double-clicking the file opens it on almost any OS, including mobile. Examples of programs that permit playback of MTS are Windows Media Player, Apple’s Final Cut Pro, and VLC media player.

 

Sometimes MTS files are large, making them difficult to manage and store. To reduce the file size, simply convert the MTS file to MP4. Cnet.com lists several options for downloadable file converters.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.

 

How to open an MKV file?

The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.

 

Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
