What is the difference between AVI, Motion JPEG and MPEG video formats

In Camcorders, people today usually use AVI and Mpeg2 formats as popular ways, while Mjpeg is the most popular format used for photo cameras.

I’d like to describe the AVI format as DV-AVI format. It’s official name is IEC 61834. Nearly all new tape driven Digital Camcorders use it. A file size of around 13 Gigabytes per hour results from the 25.146 Mbit per second’s compression rate. In this way, it produces high qualified standard definition television signal.

It is common to use Mpeg2 format for a host of different devices, such as DVD’s, HDD Camcorders, over the air and satellite TV signals. In a lot of places, people say it is “a standard for the generic coding of moving pictures and associated audio information”. What I’m going to talk about is some detailed information.

Why apple do not accept the avi and mkv files

In common use, the AVI file container is supported/accepted by QuickTime (QT Player natively supports MPEG, Motion JPEG, MP4, MOV, etc video formats). What remains problemating is the data in the file container. Neither accepting AVI files nor those containing unexpected combinations audio and video data, QuickTime apps, such as iMovie, QuickTime X, and iTunes, have been updated. But MKV would be restricted by the same codec component. In my opinion, only if the file type can be recognized/supported, it would be nice even if specific data compression formats are not natively supported by the basic OS codec component configuration. Like the iPod, iPhone, iPad, and TV, iTunes has, more or less, become a management and streaming vehicle for mobile devices and whose native support are only a very few specific dodes like MOV, (Click the link to learn how to convert avi to mov for Mac). However, our people seem to forget it. As the QT 7 based apps still continue to enjoy relatively open codec support for a dwindling number of legacy and third-party components, you can use it to play your AVI and/or MKV files.

iTunes accept mp3 support , why they don’t accept avi

Firstly, as both a file container and a compression format, mp3 outpaces AVI as only a file container. What’s more, as some legacy AVI compression formats have never been trancoded for use on the Mac and never outpace OS 9, they died with the demise of the PowerPC CPU the introduction of Lion/Mountain Lion. In contrast, as long as QT supports “muxed” MPEG-1 audio and video, MPEG-1 layered audio content supports playback. The legacy codec components are no longer available for the Mac or supported by their originators. By not trying to make its media players compatible with legacy file types and legacy codec components, Apple claims he is modernizing. Taking Microsoft for example, more than ten years ago, it gave up active support with the introduction of WMV media just because numerous file type limitations have happened in the original AVI specification and it introduced the AVI container in November of 1992 as part of its “Video for Windows Technology”.
