How can I convert MTS to MP4 on Windows 11?

Avidemux is an open-source video editor that you can use as an convert mts to mp4, but although it supports lossless stream copying, its interface is outdated.

It allows you to convert a single MTS video to MP4 while preserving the full original quality without re-encoding, but this tool does not support batch conversion of multiple files.

First, click File > Open to select the target MTS file. Set the video output to “Copy” for lossless video stream conversion, set the audio output to “Copy” to preserve the original audio track, select MP4 as the output format, and click File > Save > Save Video to export the converted file.

This allows you to transcode MTS files to standard MP4 files without any loss of quality. This tool is suitable for everyday single-video format conversions and organizing your local video library.

This tool cannot convert multiple MTS files at once, so it is only suitable for users who need to process just one video file at a time.

If you prefer not to use a paid media transcoding tool, you can try this convert mts to mp4. Its interface is somewhat outdated and lacks intuitive prompts, so you’ll need to carefully verify the video and audio settings before exporting the file.
