An editor or older HDV device may require an .m2t MPEG-2 transport stream instead of an AVCHD .mts file. Because MTS normally contains H.264 video while M2T usually contains MPEG-2 video, this conversion commonly requires transcoding rather than renaming the extension.
What the MTS format is
MTS is a transport-stream container used mainly by AVCHD camcorders and Blu-ray-compatible video workflows. It normally stores H.264/AVC video with AC-3 or LPCM audio, commonly at 1280×720 or 1920×1080 resolution.
Sony, Panasonic, Canon, and other HD camcorders create MTS clips, often inside an AVCHD directory structure alongside playlist and metadata files. Video editors such as Adobe Premiere Pro, DaVinci Resolve, and Sony VEGAS can usually import the individual clips directly.
What the M2T format is
M2T is a filename extension for an MPEG-2 transport stream, commonly associated with HDV camcorders and older broadcast or editing systems. It generally contains MPEG-2 video and MPEG audio in a transport-stream container.
An M2T file can be easier for software or hardware designed for HDV to recognize, but the extension alone does not define one universal codec, resolution, bitrate, or audio format. Compatibility depends on the receiving application or device.
How to convert MTS to M2T
Using FFmpeg
FFmpeg is suitable when the destination specifically needs MPEG-2 transport-stream video.
- Install FFmpeg and place the source file in a convenient folder.
- Open a terminal or Command Prompt in that folder.
- Run this command, replacing the filenames as needed:
ffmpeg -i input.mts -c:v mpeg2video -b:v 25M -c:a mp2 -b:a 384k -f mpegts output.m2t
This creates an MPEG-2 transport stream at approximately 25 Mb/s with MP2 audio. Use a different video bitrate or audio setting if the target device specifies one. To keep all available streams, add -map 0 before the codec options.
If the MTS file already contains MPEG-2 video and is structurally compatible with the destination, a lossless container remux may be enough:
ffmpeg -i input.mts -map 0 -c copy -f mpegts output.m2t
Most AVCHD MTS files contain H.264, so this second command preserves H.264 rather than producing the MPEG-2 format expected by many HDV systems.
Using the built-in online converter
You can convert the file for free on 101convert.com without installing software. Upload the MTS file, select M2T as the output format, start the conversion, and download the resulting file when processing finishes.
Quality and compatibility limits
Transcoding H.264 to MPEG-2 is lossy and can increase file size; choose 25 Mb/s only when it matches the target workflow. A converted M2T file will not restore detail already lost in the original recording.
Do not change the extension manually unless the source is already an MPEG-2 transport stream. Confirm the required frame rate, frame size, interlacing, audio codec, and bitrate before converting, because HDV equipment may reject otherwise valid MPEG-2 transport streams.
