MPEG4 vs MP4 ,Difference between MPEG4 and MP4

MPEG-4 and MP4 are the two terms that are easy to be confused with each other, not just because they differ by a letter but also because of the fact that they are much closely intermingled in media files like movies and music. The key difference between MPEG4 and MP4 is their function. MPEG4 is a video encoding algorithm method which defines the compression of audio and visual digital data (AV). That is actually responsible for how the images are compressed and converted into data. MPEG-4 can be used for compression of AV data for web, streaming media, CD distribution, as well as for voice broadcast television applications. MP4 is just a media container that was developed to hold the data that is encoded by an MPEG4. This means that it can be used to store audio and/or video subtitles, chapters, and relevant data.

File Extension MPEG-4 MP4 (MPEG-4 Part 14)
Developer MPEG-4 was developed by Moving Picture Experts Group (M.P.E.G), working under the joint direction of the International Standards Organization (ISO) and the International Electro-Technical Commission (IEC). This group works on standards for the coding of moving pictures and associated audio. MP4 file developed by the International Standardization Organization (ISO) which goes well with almost any kind of media player and device. Because MP4 was developed for MPEG4 encoded media, it can also be found within the MPEG-4 specification. MP4 is not the only container format under MPEG-4 but it is also a derivative of the more general MPEG-4 Part 12 specification for storing MPEG-4 files.
History The non-compressed film files are much huge in size even the computers were not able to run it. Then the manufacturers began to figure out some ways to run that video stuff on digital media for saving space and to make the streaming on internet possible and feasible, indeed. Therefore some manufacturers developed software that allowed the system to compress film so that the computer could afford the operation. There are so many methods used for algorithm of compression, but MPEG-4 is widely used nowadays. MPEG-4 has the same algorithm of compression that MPEG-1 and MPEG-2 but was expanded to support video/audio "objects", low bit-rate encoding and 3D content, text and some other media types. MP4 file was first utilized in 2001 as a standard ISO/IEC 14496-1:2001. But a few years later, it has been updated and converted to standard ISO/IEC 14496-14:2003. Both the MP4 and MOV formats make use of the similar kind of MPEG-4 format. Therefore, they conveniently work in QuickTime Environment. But MP4 is more popular as compared to the MOV because it can be operated through various types of platforms including the MACs Apple systems.
Popularity MPEG-4 opens up the potential for more exciting technological developments in the future. The MPEG group describes MPEG-4 as a multimedia platform, designed to blend animation, text and video together into one format. The object-oriented nature of the format lends itself well to user interaction. The most popular and common encoded formate is MP4 or MPEG-4 Part 14. When you watch a video on the web or your mobile phone, the odds are pretty good if you are using the MP4 video format. There are a lot of choices when it comes to video formats. But, MP4 is the top pick for both web and mobile viewing. According to a survey, 69% of video professionals use MP4 regularly for the web and 58% use it for mobile. Moreover, mp4 yeilds best result in short size which is widely used for data streaming and Internet rippers like torrents.
Data streams Data streaming is the transfer of data at a steady high-speed rate. As MPEG-4 is not a media container (Audio/vedio), it’s just encoding algorithm method which produces encoded file in different types. MP4 is the most common and widely encripted formate by MPEG-4. Most of the data embedded in mp4 and m4v are made through private streams with the streaming information of the file that usually is included separately in a hint track. The various registered codec available for these file formats are published on the MP4 registration authority website. Among the widely used codec and well supported additional data streams: • Video: MPEG-4 Part 10 and MPEG-4 Part 2
• Audio: Advanced Audio Coding, along with MPEG-4 Part 3 audio objects like Audio Lossless Coding and Scalable Lossless Coding
• Subtitle: MPEG-4 Timed Text. There also DVD Videos that uses subtitles in MP4 files.
Metadata MPEG-4 creates various kind of meta-data during decodind the media e.g the file author, software used in its creation, and the time and date when was created. The meta-data can also be structured in XMP format.
MP4 files may contain meta-data as defined by the format standard. In addition, it may contain Extensible Meta-data Platform (XMP).
There are different kind of information which can be stored in mp4 file’s metadata
• Video frames
• Audio samples
• Interleaving AV data
• Captioning data
• Chapter index
• Title
• Poster
• User data
• Various technical metadata: codec, timescale, version, preferred playback rate, preferred playback volume, movie duration, etc.
Pros • MPEG-4 is a standard, currently under development for the delivery of interactive multimedia across networks.
• It is more than a single codec and includes specifications for audio, video, and interactivity.
• The video component of MPEG-4 is very similar to H.263.
• It is optimized for delivery of video at Internet data rates.
• One implementation of MPEG-4 video is included in Microsoft’s NetShow.
There are certain benefit of using MP4 file:
• Easy to use and wide range of media players are there that are supported to MP4 codec.
• No copyright protection, Internet rippers like torrents use this format.
• Easily convert into other formats like MKV, FLV and AVI.
• MP4 files provide better video qualities in limited size which save data space in storage device.
• MP4 is the best choices for streaming because it provides best results for transferring video data over internet.
• MP4 files can be run virtually on all the major media players and sound card drivers.
• Separate hint track is used to encode streaming information.
• Can store data types other than video and audio, such as object descriptors, scene descriptors and other object oriented file structures in addition to MPEG features.
Cons The MPEG-4 file source does not support the following features of MP4 files:
• External track.s
• Movie fragments ('moof' or 'mfra' boxes) and 'moof' is supported in Windows 8.
• Streamed presentations.
• The MPEG-4 file source silently ignores hint tracks.
• Seeking by SMPTE time code.
• Compressed ('cmov') atoms.
• The only disadvantage of MP4 file format is from editing and movie making point of view, because MP4 files are not easy to edit or update.
Used by MPEG-4 is designed to be used in broadcast, interactive and conversational environments. The way MPEG-4 is built which allows it to be used in television and Web environments, not just in a periodic manner but also facilitates integration of content coming from both channels in the same multimedia scene. Its strong points are inherited from the successful MPEG-1 and -2 standards (broadcast-grade synchronisation and the choice of on-line/off-line usage) and VRML (the ability to create content using a scene description). The ratio between MP4 video quality and its size, MP4 become most common file for multimedia. Several mobile platforms, computers and handheld devices use MP4 file format as their default file format. Smart phones, iPads and Tablets make wide use of MP4 file format in order to play audio and video files. People who prefer straight and hassle-free reading and writing of their video files, will always preffer using mp4. Being the standard video format, MP4 file format is used almost everywhere.
