How to open MP4 on computer

Do you want to find out how to open MP4 acting as a computer ? Then use the solutions for Windows , macOS and Linux that you find reported below. It’s all so easy, you have absolutely nothing to worry about.

Movies & TV (Windows 10 and later)

If you have a PC with Windows 10 and later and want to open MP4 in that case, the best suggestion I can offer you is to rely on Film & TV . It is, in fact, the default and free application of the latest Microsoft operating system to play video and audio in all popular formats, including MP4. It is pre-installed, but if removed it can be downloaded again from the relevant section of the Microsoft Store .

To be able to use Film & TV for your purpose, just double-click on the icon of the MP4 file you want to open and the application will run directly, as the aforementioned format should automatically be associated with the program (otherwise, you can easily fix it by following the instructions I gave you in my guide on how to change the default program ).

Subsequently, you will see the application window appear on the Windows desktop, with the video in the center and the commands to manage playback at the bottom, which will start automatically.

As an alternative to as I just indicated, you can open the MP4 videos of your interest by right-clicking with the mouse on the file of your interest, selecting the Open with item from the context menu that is shown to you and choosing the wording Movies & TV from the further proposed menu.

QuickTime Player (macOS)

If, on the other hand, you want to open MP4 on Mac , I suggest you rely on QuickTime Player . This is the default program of the operating systems of the “bitten apple” for playing multimedia contents. It’s super easy to use, it’s pre-installed, it’s free, and it supports a large number of file formats.

To use QuickTime Player for your purpose, simply double-click on the icon of the MP4 file of your interest and the program will open automatically, since the file format in question should be associated by default with the software (if not that’s it, you can fix it by following the instructions in my post how to change default program ).

After completing the above steps, the macOS QuickTime Player window will open and the video playback, visible in the center, will automatically start. To check it, you can use the appropriate commands that you find below.

In addition to how I explained to you a moment ago, I would like to point out that you can open MP4 videos with the program in question by right-clicking with the mouse on the file of your interest and choosing the items Open with and QuickTime Player from the context menu.

VLC (Windows / macOS / Linux)

Another great tool you can consider turning to to open MP4 on your computer is VLC . In case you have never heard of it, I inform you that it is a universal media player that manages to play most audio and video file formats without resorting to codecs. It is compatible with Windows, macOS and Linux and is completely free. Note that it also integrates functions for editing and converting files.

To download VLC to your computer, go to its website and click the Download VLC button .

When the download is complete, if you are using Windows , open the .exe file obtained and, in the window that appears on the desktop, click on the Yes and OK buttons . Then, click on the Next (three consecutive times), Install and Finish buttons .

If you are using macOS , instead, open the downloaded .dmg package , drag the VLC icon into the macOS Applications folder , right-click on it and select the Open item from the context menu, then press the Open button in the window that is shown to you , in order to start the software going to circumvent the limitations imposed by Apple on applications from non-certified developers (an operation that must be performed only at the first start).

Now that the VLC main window is displayed on the screen, drag the MP4 format file you want to open on it and the video playback will automatically start, in the central part of the screen. To pause, go forwards, backwards, etc. you can use the appropriate buttons located on the toolbar at the bottom.

As an alternative to as I indicated earlier, you can open MP4 with VLC by clicking on the Media item (on Windows) or on the File item (on macOS) that you find at the top left, choosing the item Open file from the menu that appears and selecting the video of your interest.
