How can I convert MTS to MP4 on Windows 11?

FF mpeg is a fantastic, completely free MTS to MP4 converter for Windows 11! It's a powerful command-line tool that puts you in full control, and it's perfect for processing camera footage.

First, you'll need to get FF mpeg set up on your system. Here’s the quick version:

1. Download: Grab a Windows build from a trusted source like gyan.dev (the "essentials" build is perfect for this).
2. Extract: Unzip the downloaded file to a simple folder, for example, C:\ff mpeg.
3. Add to PATH: This is the key step that lets you run FF mpeg from anywhere. Search for "Environment Variables" in the Windows start menu, find the "Path" variable, and add the path to your bin folder (e.g., C:\ff mpeg\bin).
4. Verify: Open a new Command Prompt or PowerShell window and type ff mpeg -version. If you see version info, you're all set!

Once it's installed, the core command to use FF mpeg as your MTS to MP4 converter is beautifully simple. Navigate in the terminal to your folder with the .MTS files and run:

bash

ff mpeg -i input.MTS output.mp4

This tells FF mpeg to take input.MTS and create output.mp4.

To splice multiple MTS files: If your camera split a long recording, you can combine them into a single MP4 using the concat demuxer.

bash

ff mpeg -i "concat:file1.MTS|file2.MTS|file3.MTS" -c copy output.mp4

Give it a shot! It's a super handy tool to have in your back pocket once you get the hang of it. If you run into any error messages, just paste them here and we can figure it out.
