A media container format (or often referred to as wrapper layout) is a style that can consist of various kinds of data such as sound and video clip data. The information is pressed utilizing a codec.

A codec (a compound of coder and decoder) is an algorithm made use of to press and/or decompress a multimedia data stream in order to lower the number of bytes should store or send.

Some container styles are limited to sound, like WAV declare Windows, AIFF for Mac and XMF; some are limited to still photos such as FITS and also TIFF. There are likewise containers that are versatile; it could hold several kinds of audio, video Soundcloud to mp3 as well as other media such as ASF apply for Windows, MP4 and also Metros. The most usual multimedia containers are:

– 3GP – made use of by mobile phones.

– ASF – conventional WMA and WMV container.

– AVI – basic Windows container.

– Metros – open basic container.

– MPEG – common container for MPEG-1 and MPEG-2.

– MP4 – conventional container for MPEG-4.

– Ogg – free as well as an open typical container for codecs Verbs (sound) and Theora (video).

The distinctions between various container layouts turn up from 5 (5) major issues:

– Popularity. Widely sustained container.

– Overhead. Instance: A two-hour film could be 3MB bigger when in AVI than when in Matroska (MKV). The overhead is the difference between AVI as well as MKV which is 3MB.

– Assistance new codec performance and also features. Some older container formats do not sustain codec features such as VBR audio and B-frames.

– Subtitles, chapters, meta-tags, and user-data support.

– Streaming media assistance.

Below is a contrast of the different popular container formats today (from Wikipedia).


Assistance for B-frames; variable little bit rate audio; variable framework price; 3GPP Timed Text subtitle; assistance MPEG-4 Part 2, H. 263, and also H. 264/MPEG -4 AVC video clip styles; support AAC, AMR-NB, AMR-WB+, AMR-WB, HE-AAC as well as HE-AAC variation 2 audio styles.

Advanced Solutions Formats

Assistance for B-frames, phases, captions, as well as metadata/tags; variable little bit rate sound; variable structure rate; assistance virtually any type of video clip format through DMO or VFW; support almost any sound through ACM or DMO.


Assistance for B-frames; variable bit rate sound; variable frame price; phases and also captions are via a third party modification; assistance practically any kind of video clip layout with VFW; support almost any kind of audio formats with ACM.
