Overview |
| This file format stores both audio and video files for playback purposes. It is used to store files that are of high quality as file compression is less in this extension. Windows OS uses this as the default format to store multimedia files but other operating systems such as Linux, Unix and Mac also support this. The data in it is encoded by various codecs such as DivX and XviD. There is a variety of software that support these files. For instance- Microsoft Movies & TV, Windows Media Player and Apple QuickTime player; etc. Due to its low compression ability, it is widely used to make short movies, promos and advertisements; etc. It should be noted that AVI format result in large files that is why it is rarely used for video streaming. |
Technical description |
| In AVI extension, file's data is divided into blocks or chunks as it is a sub-format of RIFF(Resource Interchange file format). An identification of each chunk is done by FourCC tag. File header and metadata of video(like height, width and frame rate) are identified by ‘hdrl tag' which is sub-chunk and it is mandatory. There is one another chunk which is also obligatory that is ‘movi tag' and it has actual audio or video data. The last sub-chunk is ‘idx1 tag' and it records the offsets of the data chunks. This ‘idx1 tag' is completely optional. There is one limitation of this format that it does not contain variable bitrate data. |

Overview |
| MPG/MPEG is a file extension that uses MPEG-1 and MPEG-2 codecs for video and audio files. The lossy compression in this format leads to enhancement of the streaming and downloading speed. That is why it is very popular and widely accepted for movies. This format is compatible with both Mac/Macintosh and Windows including some other portable devices. The files that are encoded using this codec provide compressed data that has small size but the quality is not sacrificed at all. It just deletes or neglects the superfluous information that can not be noticed by the human ear. This lossy encoding takes less storage space to store data. Although this format is not efficient enough to provide excellent quality, yet, it is used most of the times due to its higher level of compatibility. |
Technical description |
| The compressed ratio in digital video files under this format is 26:1 and for audio files it is 6:1.The bit rate in MPEG-1 is about 1.5 million bits per second and it is used to compress CD data., Besides this, MPEG-2 is designed especially for digital TV broadcast and DVD as it uses a bit rate above 4 million bits per second to compress both audios and videos. It should be noted that due to backwards compatibility with MPEG-1, video decoders have the ability to play a lower bit rate. It produces high quality of compressed files. Other uses of MPEG-2 is for Cable network, satellite and television stations; etc. Furthermore, it supports 5.1 multichannel audio. |
