MPEG-4 Video File

File extension .mp4
File category video
Description The MP4 files (MPEG-4 part 14 files) are the multimedia files which are used with multiple stations and video players simultaneously, they can store not only digital audio streams and digital video but other suitable amounts of data like subtitle tracks. MP4 video format is an extremely common file format due to its very own container format and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP as well. It is also a popular file format for streaming over the Internet. For instance, YouTube videos have MP4 extension.
Technical details The technical details of MP4 files differ in great aspect and are unique as well, first released in 2001 under ISO/IEX 14496-1:2001 standards, it uses an AAC encoding to wear off unauthorized users from copying the data. The main purpose is the streaming rather than sending video or audio information. MP4 files can be used to store audio streams and, in addition, text information, subtitles and still images while MPEG format can’t do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information.

Advanced Systems Format File

File extension .asf
File category video
Description The Advanced System file is a media file used by Microsoft Window Media Player for streaming online audio and video files. The media container determines the data stream structure but not data encoding. So, the files encoded by Microsoft developers contain the .wmv or .wma extensions while other files have .asf extension. The ASF has a MIME type that allows files to be sent via the internet. Therefore, it can play audio and video directly while downloading data online.
Technical details The .asf file comes with audio, video, and metadata just the same as the MP3. It defines the album, artists, and so on. Using this file, streaming can be done in a similar way to other formats. This makes user access to the file once some bytes have been downloaded while the downloading continues and the user watches. However, it has a maximum resolution of 352×288 which is adjudged small because it is designed for streaming.
