How to Convert MPG to MP4 and Vice Versa

MPEG is a set of standards developed by and named after the Moving Picture Experts Group. The most popular formats in this class are MPEG‑1, MPEG-2, and MPEG-4.

Generally when someone talks about an MPEG format, they mean MPEG-1 or MPEG-2. Files in these formats usually have the .mpg extension. Although MPEG videos are widely used, the majority of tablets and phones don’t support this format. To make sure your movie will play on your device, you need to convert it to a more flexible format. One of the best choices is MP4 (MPEG-4) – a newer format in the MPEG class.

In this guide, you’ll learn how to convert .mpg files in three different ways: via an online platform, free software, and SuperSpeed Video Converter.

Part 1. Use the SuperSpeed MPEG-to-MP4 Converter

Part 2. Use an MP4-to-MPEG Converter That’s Free

Another way to change the format of your files is to use a free MPG-to-MP4 converter. You can find plenty of these programs on the internet. Generally, they’re harder for a beginner to use, and the conversion settings may seem confusing without a comprehensive guide. Here’s an example of how to convert video with the VLC Media Player freeware.

Step 1.Download and Install the Free Converter

Follow the link below to download the program for your operating system.

Go to the VLC website

Launch the installation file and follow the installation instructions. When the process is complete, start the app.

Step 2.Add Your MPG or MP4 Files to the Program

In the Media menu, click the Convert / Save item. Or use the Ctrl + R shortcut.

Click Add and browse to the files you want to convert. Select them and click Open. You’ll see all the selected files added to the dialogue window.

Step 3.Set the Required Format

Open the Profile list and choose Video - H.264 + MP3 (MP4) or Video - H.265 + MP3 (MP4). If you need to convert to MPEG, select the Video - MPEG-2 + MPGA (TS) profile, then click the Edit selected profile button to the right of the Profile list. In the Encapsulation tab in the dialogue window, choose MPEG-PS and click Save.

Step 4.Choose the Target Folder and Launch the Conversion

If you’ve only added one file to the program, click the Browse button and locate the folder containing that file. In the File name field, enter the new name for your file with the extension (e.g. ‘Video.mp4’ or ‘Video.mpg’). Click Save and then Start to launch the conversion. If you’ve selected multiple files, they will be saved to the same folders as the originals. If you need some way to distinguish between the originals and the converted files, check the Append ‘-converted’ to filename option and then click Start.

Now you know how to use an MP4-to-MPEG converter that’s free. But there’s still one more way to convert files, and that’s to use an online converter. Let’s talk about this third option a little more.
