Avidemux is open-source software and a lightweight tool that can convert ts to mp4 while performing lossless stream copying. Its ability to run offline and copy audio and video tracks directly without watermarks makes it a convenient and practical tool that fully preserves the original media quality.

How to Convert TS to MP4

Download and install the software from the official website.

Launch the program, select File → Open, and then select your .ts file.

Set the video output option to Copy for lossless processing.

Set the audio output option to Copy to preserve the original audio track.

Change the output format to the MP4 container.

Select File → Save → Save Video to export the MP4 file.

Disadvantages

  • The interface is outdated and old-fashioned,
  • lacks convenient batch processing features, and cannot batch-convert TS files.
  • There are almost no predefined encoding presets, and one-click operation is not available.

The software can perform lossless conversion to the TS format without causing any transcoding loss. It is suitable for users who only need basic single-file format conversion and wish to avoid any loss of video quality during the conversion process.
