ASF to AVI Software converts ASF to AVI quickly. Besides AVI, the converter could convert ASF to common video formats and portable devices, for example, DivX, Xvid, 3GP, MKV, MPEG, iPad, WebM, M4V, FLV, BlackBerry, and so on.
The converter is an all-in-one video converter that supports more than 100 video and audio file formats and converts to 40 popular formats. It could convert DXA to FLV, NSV to OGV, PSX to OGV, THD to WebM, FLIC to M4V, MPEG to 3G2, MPG to 3GP, ROQ to PSP, and so on.
ASF to AVI Software supports batch conversion and is full compatible with 32-bit and 64-bit editions Vista and Windows 7.
What is ASF?
ASF is based on serialized objects which are essentially byte sequences identified by a GUID marker.
The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives.
The most common filetypes contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). Note that the file extension abbreviations are different from the codecs which have the same name. Files containing only WMA audio can be named using a .WMA extension, and files of audio and video content may have the extension .WMV. Both may use the .ASF extension if desired.
ASF files can also contain objects representing metadata, such as the artist, title, album and genre for an audio track, or the director of a video track, much like the ID3 tags of MP3 files. It supports scalable media types and stream prioritization; as such, it is a format optimized for streaming.
The ASF container provides the framework for digital rights management in Windows Media Audio and Windows Media Video. An analysis of an older scheme used in WMA reveals that it is using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing function.
ASF container-based media is usually streamed on the internet either through the MMS protocol or the RTSP protocol.
What is AVI?
There is slight overhead when used with popular MPEG-4 codecs (Xvid and DivX, for example), increasing file size more than necessary. The AVI container has no native support for modern MPEG-4 features like B-Frames. Hacks are sometimes used to enable modern MPEG-4 features and subtitles, however, this is the source of playback incompatibilities.
