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 |
| OGV is a free and an open container format for digital media(Audio, Video and text). It is unpatented software and can be used by users free of cost. It compresses the files using lossy compression and discards the redundant information which human ear incapable to process. It is used especially for online streaming. Furthermore, this format is also good for data manipulation and it is standardized by OGG Vorbis. This format is a container format used for Audio, Video and metadata files. For compressing of files, it uses Vorbis Compression Technology. The recorded content can be played using different software like VideoLan VLC Media player and Helix player; etc. |
Technical description |
| An OGV file can have separate unrestricted open-source codecs for varied media types like audio, video, text. Theora and DivX are some examples. It supports variable bit rate and based on Discrete cosine transform (DCT) compression pattern. To compress or encode videos it uses Chroma subsampling (Due to low acuity for colours by humans, it uses less resolution to encode images),block-based motion compensation and an 8-by-8 DCT block. The pixels in it are grouped together in various structures- blocks, super blocks and macroblocks. Videos on the web pages can be played using HTML coding i.e. HTML5< video > tag. Although these files have different source code, yet, the videos in this format are often addressed as OGG files in HTML source code. In addition to this, a DirectShow codec pack is provided by the developers so that this format can be used both as open-source and for commercial applications as well. |
