Convert ASF to 3GP
|
The article introduces how to convert converts ASF files to 3GP
with an easy-to-use ASF to 3GP Converter Software. The software could encode
3GP file with different codecs such as H.263, H.264, MPEG-4, AMR-NB, and AAC.
It's an ideal 3GP converter for your mobile phone. Besides 3GP, the software supports
popular formats such as 3GP, MP2, WMA, MOV, M4A (MPEG-4 audio), 3G2, M4B (MPEG-4 audiobook), etc.
The software could convert MKV to WAV, MPEG to PPM image sequence, 3G2 to MP4, M4V to JPG image sequence, DVD to AVI,
and so on.
ASF to 3GP Software supports batch conversion and, is compatible with Windows 10/8/7/Vista/XP/2000.
What is ASF?
ASF stands for Advanced Systems Format. ASF is an extensible file format
designed to store synchronized multimedia data. The advantage of ASF format
is that you may begin playing your video file before it is streamed to
the end. Instead of specifying how (i.e. with which codec) the video or
audio should be encoded, ASF does more in the structure of the video/audio
stream which is quite similar to the function performed by the AVI, QuickTime,
or Ogg container formats. ASF files specify the structure of the audio
or video stream, but not the encoding method. ASF is most commonly used
for streaming media purposes. Windows Media Audio (WMA) and Windows Media
Video (WMV) are the most common file types contained in an ASF file. The
ASF specification has been submitted to the ISO (International Organization
for Standardization) for consideration. Note that the file extension abbreviations
are different from the codecs which have the same name. An ASF file consists
of three objects: a Header object containing information about the file
itself, a Data object containing the media streams, and an optional Index
object that can help support random access to data within the file. They
often contain Windows Media Audio (.WMA) or Windows Media Video (.WMV)
data. Files of ASF format support playback from digital media servers,
HTTP servers, and local storage devices. The Advanced Systems Format (ASF)
is the file format used by Windows Media. They can be compressed using
a variety of video codecs. It supports scalable media types and stream
prioritization; as such, it is a format optimized for streaming. It supports
data delivery over a wide variety of networks and protocols while still
proving suitable for local playback.
What is 3GP?
3GP is a multimedia container format defined by the Third Generation Partnership
Project (3GPP) for use on 3G mobile phones but can also be played on some
2G and 4G phones. Audio imported from CD onto a PlayStation 3 when it is
set to encode to the MPEG-4 AAC codec will copy onto USB devices in the
3GP format. The 3GP file type is primarily associated with '3GPP'. Most
3G capable mobile phones support the playback and recording of video in
3GP format (memory, maximum filesize for playback and recording, and resolution
limits exist and vary). Defined by the 3rd Generation Partnership Project
and 3rd Generation Partnership Project 2 respectively, these standards
seek to provide uniform delivery of rich multimedia over newly evolved,
broadband mobile networks (3rd generation networks) to the latest multimedia-enabled
wireless devices. The MP4 and the AVC file format specifications described
usage of MPEG-4 content in the ISO base media file format. These extensions
were registered by the registration authority for code-points in ISO base
media file format ("MP4 Family" files). 3GPP is the new worldwide
standards for the creation, delivery and playback of multimedia over 3rd
generation, high-speed wireless networks. Some cell phones use the .mp4
extension for 3GP video. The Nintendo DSi supports .3gp on an SD card.
A 3GP file is always big-endian, storing and transferring the most significant
bytes first. It also contains descriptions of image sizes and bitrate.
For the storage of MPEG-4 media specific information in 3GP files, the
3GP specification refers to MP4 and the AVC file format, which are also
based on the ISO base media file format.
