Best Way to Convert AVI to MPEG-4

The AVI file type (only a container and not a FINAL video format) is by far the oldest used container till today. Video files that are named under the .avi extension are still very popular. This video container covers almost any video coding formats and audio coding formats. When the AVI file can not be played by the device or media player that claimed support AVI file, it may be caused by the unrecognizable video/audio codec. So you may want to convert the AVI to MPEG-4 for playback on more portable devices. Read on to get more information.

MPEG4 vs MP4: What Is the Difference between MP4 and MPEG4?

1. MPEG4 file format equals to MP4; (Incorrect)
2. MPEG-4 is just the long version of what is commonly called MP4; (Incorrect)
3. MP4 is just audio and music. MPEG4 is video, used in movies and TV shows, etc; (Incorrect)
4. MP4 is video files on or for mobile devices while mpeg4 is just regular video files; (Incorrect)
5. MP4 is a container for mpeg-4 video. There are other containers, like MKV, which also can have mpeg-4 video files in them. When devices, like iPhone, do not support MKV (MPEG-4), you can convert MKV to MP4/mpeg4. (Correct)

MPEG-4 and MP4

Normally, when we say MP4 video, we’re talking about a video ending in the file extension .mp4. MP4 can refer to a video file extension while MPEG4 cannot. Of course, there are some other differences between mp4 and mpeg4. To figure them out, you have to understand two basic terms first: media container and video codec. It is as simple as this formula: 
Media Container = video format (video codec) + audio format (audio codec) + subtitle

To make the difference of MP4 and MPEG4 much clearer, let’s apply the formula to the "mpeg4 vs mp4":
MP4 (.mp4) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc) + subtitle
AVI (.avi) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc) + subtitle
MKV (.mkv) = MP4 video format (.mpeg4/.h264 video codec) + audio format (mp3, aac, etc) + subtitle

Conclusion:

Can you see the difference MPEG-4 and MP4 from above? They are not the same thing. One the MP4 is a container and should covers lots of video/audio coding formats like: HEVC/MPEG-H Part 2/H.265, MPEG-2 Part 2, MPEG-4 ASP, H.264/MPEG-4 AVC, H.263, VC-1, Dirac, and more. While MPEG-4 is just one of them. Just like MP4, AVI is also a container and alomst covers any codec in this world.
