Video and audio standards and formats are always changing to offer better quality and more efficient disk space utilization. MP4 is one of such newer standards. It uses a compressed file system to provide better and more enjoyable video and audio quality at less the normal size of earlier standards. This multimedia file format is used as a container of both audio and video media, in contrast with MP3 which is a file format container for only audio. MP4, which is the latest industry standard in video and audio files compression, is very efficient for Internet multimedia broadcasting and for playing on small mobile devices. It is developed by ISO and the Motion Picture Expert Group (MPEG), the body responsible for regulating digital video and audio. The dynamics of MP4 makes it possible for video, audio, still images etc to be combined in a single file, at the same time efficiently utilizing disk space, ensuring that greater use is made of available disk space. MP4 also makes it possible for streaming video and audio to be used in Internet live broadcast or podcast.
MP4 video format is also used in storing video and audio files for playing them on devices such as iPod, iPhones, and other small multimedia devices. MP4 or MPEG-4 files come with the.mp4 file extension indicating their file group. MP4 devices can also play other files without the.mp4 extensions, such as 3GP files for example. Some software multimedia decoders/players which can be associated with MP4 are Winamp, iTunes, and QuickTime. MP4, which is one of the newer file format versions in the market, can also be edited or converted to other formats with the use of a suitable MP4 video editor.
Editing mp4 files means cutting, trimming, and adding various video effects. Files containing video and audio can also be separated, so that the audio files can be enjoyed without the video. Mp4 video editors can also edit mp4 files and save them in other formats such as AVI format, MJPEG, MPG, DVD, 3GP etc.
There are several MP4 video editors in the market today, each with its own claims, features and advantages. Also, there are the free downloadable versions on the internet, with limited features and with their associated risks (containers of viruses, malware, etc). An MP4 Video Editor or Converter software with a trial version is a great option because you can download and test the software first before buying it.
The sequence of steps to follow in editing mp4 video files depends on the MP4 video editor software. Some are easy to follow and provide a wizard with guidance, while others will need you to personally or manually perform the editing functions. Applications such as QuickTime, iTunes, Windows Media Player, RealPlayer, and VLC can all play mp4 files.
The benefits of mp4 become more obvious when considering how easy it is to send, receive and view video and streaming live video on the internet in real time; and also the ability to save such files for future use.
The mp4 file extension has been around since 1998, and by 1999 it became the file extension of choice for internet related multimedia transfers. Since then, it has continued to enjoy attention and more followership and usage. And it is an open source standard, meaning that anyone who wants to write a program or build hardware is free to use its source code in such a venture.
