MPEG, one of the major media formats, has many different versions. Each version has different features and applications. If you haven't looked into the subject matter before, it cannot be easy to understand what these formats do and how they relate. MPEG-2 and MPEG-4 are often compared as two versions of MPEG used in a wide range of applications, and people often struggle to decide which one to choose.
In order to answer your questions and choose the format that suits you better, we will analyze MPEG-2 VS. MPEG-4 in detail. We will also prepare a tool for you to convert between MPEG-2 and MPEG-4 smoothly. Read on to learn more!
Part 1. What is MPEG-2?
MPEG-2 is a file format developed by Mitsubishi Electric, Sony, and Thomson in 1994. This format generally applies to digital television broadcasts, DVDs, VCD, etc. It was originally designed to compensate for MPEG-1's shortcomings. MPEG-2 files usually have extensions, including .mpeg, .mpg, .m2v, .mp2, or sometimes .mp3. This format applies lossless compression techniques for multi-media files to reduce their size.
Part 2. What is MPEG-4?
MPEG-4 is a group of video and audio compression standards developed by the Moving Picture Experts Group in 1998. This format mainly distributes multimedia files on mobile devices and the Internet. MPEG-4 aims to compress the file size smaller while ensuring that the quality of the file is not compromised. It is also currently used in a fairly wide range of applications, supporting not only 2D content but also 3D. MPEG-4 files always have the extension of .mp4, .m4a, .m4b, .m4r, .m4v, etc.
Part 3. MPEG-2 VS MPEG-4
After briefly introducing the concepts of MPEG-2 and MPEG-4, we will analyze the differences between the two in four aspects: compression rate, file size, video quality, and application scenarios. Hopefully, after reading this part, you can more precisely locate the format you need.
In terms of compression rate, MPEG-4 is higher than MPEG-2 because it enjoys an advanced compression algorithm compared with MPEG-2. MPEG-2 applies lossy video and audio data compression methods.
MPEG-2 files are generally larger than MPEG-4 format files for different compression methods and other reasons. This makes MPEG-4 files relatively more suitable for distribution over the Internet.
MPEG-2 file format aims to produce lossless quality and is not specially designed for online streaming. So MPEG-2 files always enjoy a higher video and audio quality. Accordingly, they will be larger. But the quality of MPEG-4 files is also quite good, with some inevitable loss of quality for ease of distribution.
To help you visualize their different characteristics, we will simply use a table to present the above.
While MPEG-2 and MPEG-4 specialize in their areas, MPEG-4 is generally more widely applicable than MPEG-2. MPEG-2 is more suitable for broadcast television and DVDs, while MPEG-4 files are more suitable for mobile devices and Internet streaming. Particularly prominent among these is the MP4. which can be played on almost any platform. So if you want higher adaptability, you can convert MPEG to MP4.
|Compression Rate||Lossy data compression methods||Enjoys an advanced compression algorithm|
|File Size||Larger||Relatively small, more suitable for distribution|
|Video Quality||Enjoy a higher video and audio quality||The inevitable loss of quality for ease of distribution|
|Application||More suitable for broadcast television and DVDs||More widely applicable; suitable for mobile devices and Internet streaming|

Part 5 FAQs about MPEG-2 VS MPEG-4
Is MPEG-2 outdated?
Although more advanced versions of MPEG have been developed, MPEG-2 is currently quite widely used. It is still used in over-the-air digital television broadcasting and the DVD-Video standard. It still enjoys wide compatibility with most existing software and hardware. Thus MPEG-2 is not yet outdated.
Is an MPEG-4 the same as MP4?
The full name of MP4 is MPEG-4 Part 14. MP4 is not exactly equivalent to MPEG-4. MP4 is the video container format that holds the data, while MPEG-4 is the standard for encoding video content within files. In general, the data in an MP4 file is encoded according to the MPEG-4 standard.
What is the difference between MPEG and MP3?
The biggest difference is that MPEG can be used for video and audio files, whereas MP3 is limited to audio files only. MP3 is a version of MPEG that is used exclusively for audio and is known as MPEG-1 Audio Layer 3, which is more commonly used for distributing and compressing audio files. Sometimes one will need to convert MPEG to MP3 in order to avoid incompatibility.
Which MPEG is the best?
The best and most widespread of the current MPEG versions is MPEG-4, which enables the storage of high-quality video and is highly compatible. MPEG-4 files are not too large, and this feature makes it possible to be played and distributed on almost all major platforms. It is also currently one of the most usable of all video formats.
Is it legal to convert MPEG files on DVDs?
If you're burning the file for saving or viewing personally, there's no problem. But you should never use the burned CDs or saved videos for commercial purposes because copyright regulations may protect these file classes and can only be used for other purposes with the author's permission.
