Is MPEG4 the same as MP4? The answer is no. People often confuse these two concepts. When your device doesn't support MPEG4, you can convert it to MP4, the widely compatible format. This article will look at the difference between MPEG4 and MP4, as well as how to convert MPEG4 to MP4 on your device for easy access.

Quickly jump to the tools you need:

What is MPEG4 format?

MPEG-4 is a compression method applied to define audio and video data (AV). So far, it is divided into 33 parts. Each part supports various codecs. For example,

• Part 2: DivX, Xvid, 3ivx, Nero Digital, etc. video codecs
• Part 3: AAC, ALS, SLS, etc. audio codecs
• Part 10: AVC/H.264 video codec
• Part 14: MP4 file format

By adopting these video and audio coding formats, files can be compressed into different specs and for different use.

What is MP4 format?

MP4 was originated in the MOV format and conceived as MPEG-4 Part 12. Over the years, it evolved into MPEG-4 Part 14. It is a storage or container format and it can't compress video files.

Why convert MPEG4 to MP4?

MPEG-4 video and audio codecs are not necessarily be wrapped in an MP4 container, whereas MP4 is not necessarily encoded with MPEG4.

Therefore, in two cases you may need to change MPEG4 videos to MP4:

1. Convert AVI MPEG4, MKV MPEG4, etc. to MP4.

MPEG4 is packaged in AVI, MKV, etc., which make you unable to play the MPEG4 on QuickTime, iTunes, or other applications.

2. Convert MP4 MPEG4 to MP4 H264 or MP4 H265.

MPEG4 has lower coding complexity and efficiency. It's only suitable for environments with relatively lower encoder hardware conditions. H264 and H265 have higher coding efficiency, which keep higher quality at the same file sizes. Encoding level: H265 > H264 > MPEG4.
