How to Convert MPEG to MP4: 5 Easy Methods That Work

An old MPEG or MPG video may still play on your computer, but sharing it with a phone, web browser, smart TV or video editor can be less straightforward. Converting the file to MP4 usually solves the problem and can also make the video easier to upload, archive and manage.

The most widely compatible choice is normally an MP4 file containing H.264 video and AAC audio. However, the right conversion method depends on the size of your video, the number of files you need to process and whether you are comfortable uploading the footage to an online service.

In this guide, we explain how to convert MPEG to MP4 with the best video converter software on computer, online, and smartphones. We also cover the settings that matter, how to minimize quality loss and the difference between transcoding and simply changing a file extension.

MPEG vs MP4: What Is Actually Being Converted

MPEG and MP4 are related terms, but they do not describe exactly the same thing.

MPEG is the name of the Moving Picture Experts Group and a family of video and audio standards. The extension alone does not reveal every technical detail about the file, but files ending in .mpeg or .mpg commonly contain MPEG-1 or MPEG-2 video.

MP4 is a multimedia container. It can hold video, audio, subtitles, chapters and metadata. The video inside an MP4 file may be encoded with H.264, HEVC, MPEG-4 Part 2 or another compatible codec.

This distinction matters because converting MPEG to MP4 can involve one of two processes:

📦 Remuxing moves existing video and audio streams of an MPEG file into a different container without encoding them again. This is faster and does not alter the encoded video, but it only works when the original streams are compatible with the destination container.

🔄 Transcoding decodes the original media stream and re-encodes them using different settings or codecs. Many older MPEG-1 and MPEG-2 videos need to be transcoded to H.264 to achieve reliable playback on current devices and websites.

In practice, transcoding MPEG to MP4 is the more common approach because it creates an MP4 file with codecs that are widely supported by current devices and platforms. However, some of the methods covered in this guide can also remux MPEG streams into an MP4 container when re-encoding is unnecessary. We will point out which tools support each option.

Which MPEG-to-MP4 Method Should You Choose

Our recommendation:

For a large MPEG file or a folder containing multiple videos, a desktop converter is usually the most practical option. VideoProc Converter AI provides a more guided workflow, batch processing, hardware acceleration, and ready-made device presets. HandBrake is the stronger choice for users who need a completely free and open-source desktop converter.

VLC works well for an occasional one-off conversion when it is already installed. An online converter is convenient for a small, non-sensitive video, but it is less suitable for private footage, slow internet connections, or multi-gigabyte files. iMovie is useful when the MPEG file imports successfully and basic editing is required before export.

Method 1. Convert MPEG to MP4 on Windows and Mac

Best for: Large files, batch conversion or remuxing, fast speed, ready-made device profiles, and AI quality enhancement.

VideoProc Converter AI provides a simple way to convert MPEG to MP4, especially for older videos from DVDs, camcorders, TV recordings, or legacy media libraries. Its ready-made profiles let you export videos for iPhone, iPad, Android devices, smart TVs, Xbox, PlayStation, YouTube, Facebook, and more without manually adjusting complex codec settings.

It supports more than 420 formats and device profiles, including MPEG-1, MPEG-2, MPEG-4, and MPG, making it useful for mixed collections of old video files. Level-3 hardware acceleration helps process large or lengthy MPEG videos at up to 47 times real-time playback while keeping CPU usage relatively low, although actual speed depends on the hardware and output settings.

You can also trim, crop, merge, and compress MPEG videos before conversion. For low-resolution footage, the built-in Super Resolution tool can upscale video to as high as 4K and improve perceived sharpness, helping older MPEG recordings look better on modern displays.

How to Convert MPEG to MP4 with VideoProc

Step 1. Launch VideoProc Converter AI on Windows or Mac.

Step 2. Select "Video Converter" on the main interface and drag .mpeg videos to it to import.

Step 3. Click Video in the output-format section at the bottom of the interface. Find MP4 Video, then choose H.264 MP4 for the widest compatibility, HEVC MP4 for a smaller file at similar quality, or AV1 MP4 for more efficient compression on supported devices.

Tips:

Methdod 4. Convert MPEG to MP4 for Free with HandBrake

Best for: Users who want a completely free, open-source MPEG-to-MP4 converter with detailed control over video quality and compression.

HandBrake is a popular video transcoder available for Windows, macOS, and Linux. It can open common MPEG and MPG files and convert them into MP4, MKV, or WebM. Unlike a basic one-click converter, HandBrake gives you control over the video encoder, quality level, frame rate, dimensions, audio tracks, subtitles, and filters.

Its built-in presets make the process more approachable. The General presets create MP4 files intended to work with a wide range of devices and applications, while separate presets are available for Android devices, Apple products, PlayStation, Xbox, Roku, Chromecast, and online sharing. However, it is primarily a transcoder. It re-encodes the video rather than simply moving the original MPEG stream into an MP4 container, so it is not the best choice when you only want to remux MPEG to MP4.

How to convert MPEG to MP4 for Free with HandBrake

Step 1. Download and install HandBrake, then open the program. Click Open Source and select the MPEG or MPG file. You can also drag the video directly into the HandBrake window.

Step 2. Open the Preset menu and choose a preset that matches the source video. Fast 1080p30 is a suitable starting point for most HD videos, while Fast 720p30 works well for lower-resolution footage.

Step 3. Open the Summary tab and make sure MP4 is selected as the output format. Go to the Video tab and select H.264 (x264) for broad compatibility. Keep the frame rate set to Same as source.

Step 4. Check the Dimensions tab and keep the original resolution. If the MPEG video shows horizontal lines during movement, open Filters and enable Decomb. Open the Audio tab and select AAC as the audio codec. Then click Browse and choose the output folder and filename.

Step 5. Click Start Encode to convert the MPEG file to MP4. When the process is complete, play the output file to check the image quality, sound, and aspect ratio.

Choose iMovie if:

• The MPEG or MPG file imports successfully.
• iMovie is already part of the existing Mac workflow.
• Trimming, cropping, stabilization, or other edits are needed before export.
• Only one or two videos need to be processed.
• Using software already installed on the Mac is preferred.

Look elsewhere if:

• The MPEG file cannot be imported into iMovie.
• Only remuxing is required, with no re-encoding.
• Several MPEG files need to be converted in a batch.
• Detailed control over codecs, bitrate, audio tracks, or subtitles is required.
• No editing is needed before format conversion.

Method 5. Convert MPEG to MP4 for Free with iMovie

Best for: Mac users who want to make basic edits before exporting a compatible MPEG video as MP4.

iMovie is a free video editor included with most Macs. It is a practical option when you already have it installed and want to trim unwanted footage, crop the frame, correct colors, stabilize shaky video, or add titles before converting the file.

However, iMovie is not a universal MPEG converter. Some MPEG and MPG files, particularly older videos using MPEG-1, MPEG-2, or specialized audio codecs, may not import successfully. Apple notes that older or specialized media formats may not work when the device, operating system, or application does not support the format.

Step 1. Open iMovie on your Mac. In the Projects window, click Create New, then select Movie to create a blank project.

Step 2. Click the Import Media button at the top of the window. Locate the MPEG or MPG file, select it, and click Import Selected.

Step 3. Once the video appears in the media browser, drag it onto the timeline at the bottom of the window. You can also select the clip and press the E key to add it to the movie.

Step 4. Make any necessary edits. For example, you can trim the beginning or end, split the clip, crop black borders, adjust the color, stabilize shaky footage, or change the audio volume. Skip this step when you only need format conversion.

Step 5. Click the Share button in the upper-right corner and select Export File. Alternatively, choose File > Share > File from the menu bar. Apple’s current iMovie guide uses this workflow to export a project as a standalone video file.

Step 6. Set Format to include both video and audio. Choose a resolution that matches the original MPEG file. Click Next, enter a filename, choose the destination folder, and click Save.

Choose iMovie if:

• The MPEG or MPG file imports successfully into iMovie.
• You already use iMovie on your Mac.
• You want to trim, crop, stabilize, or edit the video before exporting it.
• You only need to process one or two videos.
• You prefer to use software that is already available on your Mac.

Look elsewhere if:

• iMovie cannot import the MPEG file.
• You only want to remux the video without re-encoding it.
• You need to convert multiple MPEG files in a batch.
• You want detailed control over the video codec, bitrate, audio tracks, or subtitles.
• You only need format conversion and do not require video editing.
