Convert 3GPP to WMV
3GPP to WMV Conversion Software converts 3GPP files to WMV.
The software is an easy to use and professional video converter. 3GPP
to WMV Conversion Software could choose the best fit bit rate automatically when
converting file, so that the converter will keep original video and audio quality.
And, size of outputted file is acceptable. You could also customize video size,
frame rate, and bit rate. The software also supports common file format such as
OGV, Archos, VCD, WebM, DV, PS3, DivX, SWF, etc. It could convert M4V to WebM, EVO to WebM, F4V to Zune, 3GPP to iPhone, EVO to OGV, F4V to AVI, and so on.
3GPP to WMV Conversion Software supports batch conversion
that enables you convert bulk 3GPP files to WMV at a time. The software is
full compatible with 32-bit and 64-bit Windows 10/8/7/Vista/XP/2000.
What is 3GPP?
3GP (3GPP file format) is a multimedia container format defined by the Third Generation
Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile
phones but can also be played on some 2G and 4G phones.
3GP is defined in ETSI 3GPP technical specification. 3GP is required file format
for video and associated speech/audio media types and timed text in ETSI 3GPP
technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging
Service (MMS) and Transparent end-to-end Packet-switched Streaming Service (PSS).
The 3GP file format stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4
Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC
v1 or Enhanced aacPlus (HE-AAC v2). 3GPP allowed use of AMR and H.263 codecs in
the ISO base media file format (MPEG-4 Part 12), because 3GPP specified the usage
of the Sample Entry and template fields in the ISO base media file format as well
as defining new boxes to which codecs refer. These extensions was registered by
the registration authority for code-points in ISO base media file format ("MP4
Family" files). 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. The MP4 and the AVC file format
specifications described usage of MPEG-4 content in the ISO base media file format.
What is WMV?
Windows Media Video (WMV) is a compressed video file format for several proprietary
codecs developed by Microsoft. The original codec, known as WMV, was originally
designed for Internet streaming applications, as a competitor to RealVideo. The
other codecs, such as WMV Screen and WMV Image, cater for specialized content.
Through standardization from the Society of Motion Picture and Television Engineers
(SMPTE), WMV has gained adoption for physical-delivery formats such as HD DVD
and Blu-ray Disc.
A WMV file is in most circumstances encapsulated in the Advanced Systems Format
(ASF) container format. The file extension .WMV typically describes ASF files
that use Windows Media Video codecs. The audio codec used in conjunction with
Windows Media Video is typically some version of Windows Media Audio, or in rarer
cases, the deprecated Sipro ACELP.net audio codec. Microsoft recommends that ASF
files containing non-Windows Media codecs use the generic .ASF file extension.
The ASF container can optionally support digital rights management 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.
Although WMV is generally packed into the ASF container format, it can also
be put into the AVI or Matroska container format. The resulting files have the
.AVI and .MKV file extensions, respectively. WMV can be stored in an AVI file
when using the WMV 9 Video Compression Manager (VCM) codec implementation. Another
common way to store WMV in an AVI file is to use the VirtualDub encoder.
Windows Media Video (WMV) is the most recognized video format within the WMV
family. Usage of the term WMV often refers to the Microsoft Windows Media Video
codec only. Its main competitors are MPEG-4 AVC, AVS, RealVideo, DivX, and Xvid.
The first version of the codec, WMV 7, was introduced in 1999, and was built upon
Microsoft's implementation of MPEG-4 Part 2. Continued proprietary development
led to newer versions of the codec, but the bit stream syntax was not frozen until
WMV 9. While all versions of WMV support variable bit rate, average bit rate,
and constant bit rate, WMV 9 introduced several important features including native
support for interlaced video, non-square pixels, and frame interpolation. WMV
9 also introduced a new profile titled Windows Media Video 9 Professional, which
is activated automatically whenever the video resolution exceeds 300,000 pixels
(e.g., 528x576, 640x480 or 768x432 and beyond) and the bitrate 1000 kbit/s. It
is targeted towards high-definition video content, at resolutions such as 720p
