Free online M2V to TS converter

Source format

M2V is a MPEG-2 video elementary stream. It contains video only, with no audio, subtitles, or container metadata. It is commonly used in DVD authoring, video editing, and broadcast workflows where the video stream is stored separately from audio. Because it is an elementary stream, an M2V file usually needs to be paired with other files or placed into a container before it can be played conveniently.

Target format

TS usually means MPEG transport stream (.ts). This is a container designed for reliable transmission and streaming of audio/video data. It is widely used for broadcast TV, IPTV, HLS streaming, and media distribution where resilience to packet loss matters. A TS file can hold video, audio, subtitles, and timing information in a format that many players and devices support.

How to perform the conversion

The best approach is usually to remux the M2V video into a TS container, because the video codec is already MPEG-2 and often does not need re-encoding. The most reliable tool for this is FFmpeg.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt in the folder containing the M2V file.
3. Run a command like ffmpeg -i input.m2v -c:v copy output.ts.
4. If the file has no audio, this command will create a TS file containing the video stream only.
5. If you also have an audio file, you can mux it together, for example: ffmpeg -i input.m2v -i audio.ac3 -c:v copy -c:a copy output.ts.

If you prefer a graphical workflow, some video editors and muxing tools can open an M2V stream and export or save it as TS. In such software, look for File → Open or Import, then File → Export or Save as, and choose MPEG-TS or Transport stream as the output format.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and compatibility

Because M2V is already MPEG-2 video, using -c:v copy preserves the original quality and is much faster than re-encoding. However, M2V alone does not include audio, so a TS file made from only an M2V stream may be silent unless you add an audio track. Some players expect TS files to contain proper timestamps and stream headers, so if playback is problematic, a full remux with FFmpeg is usually better than simple file renaming. Also, TS is a container, not a codec, so compatibility depends on the streams inside it; MPEG-2 video is broadly supported, but older devices may have stricter requirements for resolution, frame rate, or audio format.
