What is a TS file?

A TS file is a Video Transport Stream (TS) file that stores video data compressed with standard MPEG-2 (.MPEG) video compression. The TS format is often utilized for saving video on a DVD disc but may also be used to store streamed or broadcast video.

You will most likely encounter TS files on DVDs. For example, when viewing video files burned onto a DVD, you may find a sequence of TS files named moviename1.ts, moviename2.ts, moviename3.ts, and so on.

TS files were common during the height of DVDs in the 1990s and 2000s. However, as technology and multimedia formats (.M2TS, .MP4, etc.) have progressed, the TS format has become more obscure.

How to open a TS file

You can open a TS file with various media players and video editors, including VideoLAN VLC media player, Corel VideoStudio, and Audials One.

For example, to open a TS file with VLC media player:

  1. Select Media/File → Open File….
  2. Navigate to the folder containing the TS file.
  3. Select the TS file and either click Open or double-click the file to open it.

You can also rename the .ts file extension to .mpeg and open it with an application that supports MPEG video.

How to convert a TS file

Several media players and video editors, including VideoLAN VLC media player and Corel VideoStudio, can convert TS files to other formats.

For example, VLC media player can convert TS files to the following formats:

  • .MP4 - MPEG-4 Video
  • .WEBM - WebM Video
  • .ASF - Advanced Systems Format
  • .MP3 - MP3 Audio
  • .OGG - Ogg Vorbis Audio

What is a TS file?

A TS file is a text file that contains TypeScript code, an open source programming language developed by Microsoft. TypeScript is a superset of ECMAScript 2015, which is a superset of JavaScript. It is used for developing medium- to large-scale JavaScript applications for server-side or client-side execution. TS files are similar to JavaScript .JS files.

More Information

TypeScript was made public in late 2012 and was developed for the purpose of easing the development of components in complex JavaScript code. It is a statically typed superset of JavaScript that compiles to plain JavaScript, which can be run on web browsers, in Node.js, or in any JavaScript engine supporting ECMAScript 3 or later. The language extension comes with all the features of JavaScript while adding features such as static type checking, interfaces, type erasure, enumerated type, and namespaces.
