How can I convert .ts to .mp4 on Windows 11?

If you're comfortable with a little bit of command-line work, MP4Box is a free and powerful tool from the GPAC project. It's great for this specific task because its main purpose is to repackage media into standard MP4 files. Importantly, it doesn't re-encode the video by default, meaning your video quality is perfectly preserved.

How to convert ts to MP4:

1. Download and install the GPAC software packag.

2. Open Command Prompt or PowerShell on your Windows 11 PC.

3. Navigate to the folder where your .ts files are located. You can do this by typing cd [your- folder- path].

4. Run a simple command to convert a single file. The most basic command looks like this:

mp4box - add your- video, ts -new your-video, mp4

If your video is split into multiple .ts files, you can combine and convert them in one go by listing them all with the -add option.

A Couple of Quick Heads-Ups

• What it does (and doesn't do): MP4Box is mainly a "repackager," not a re-encoder. This is usually a win because it's fast – it's mostly just moving the video and audio streams into a new MP4 container without re-encoding them. So if your .ts file uses a codec that's already MP4-friendly you're golden.
• If it gets picky: Some older forum posts mention that MP4Box might not love every single .ts file, especially ones with quirks or errors. If you run into trouble, the command above is the place to start. For more complex stuff (like preserving specific timestamps or dealing with live streams), you might need to look into its more advanced options.

So, for a fast and clean way to convert ts to mp4 without having to fire up a heavy video editor, the -add and -new combo is your new best friend.
