Convert MP4 to WMV
MP4 to WMV Conversion Software converts MP4 files to WMV.
The software is an easy to use and professional video converter. MP4
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
iPhone, Archos, WebM, AVI, OGM, iRiver, VCD, DivX, etc. It could convert F4V to Xbox 360, RMVB to Xvid, MPG to DivX, H264 to Zune, EVO to iPad, H264 to 3G2, and so on.
MP4 to WMV Conversion Software supports batch conversion
that enables you convert bulk MP4 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 MP4?
MPEG-4 Part 14, formally ISO/IEC 14496-14:2003, is a multimedia container format
standard specified as a part of MPEG-4. It is most commonly used to store digital
audio and digital video streams, especially those defined by MPEG, but can also
be used to store other data such as subtitles and still images. Like most modern
container formats, MPEG-4 Part 14 allows streaming over the Internet. The official
filename extension for MPEG-4 Part 14 files is .mp4, thus the container format
is often referred to simply as MP4.
MPEG-4 is a patented collection of methods defining compression of audio and
visual (AV) digital data. It was introduced in late 1998 and designated a standard
for a group of audio and video coding formats and related technology agreed upon
by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under
the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses
of MPEG-4 include compression of AV data for web (streaming media) and CD distribution,
voice (telephone, videophone) and broadcast television applications.
MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related
standards, adding new features such as (extended) VRML support for 3D rendering,
object-oriented composite files (including audio, video and VRML objects), support
for externally-specified Digital Rights Management and various types of interactivity.
AAC (Advanced Audio Coding) was standardized as an adjunct to MPEG-2 (as Part
7) before MPEG-4 was issued.
MPEG-4 is still a developing standard and is divided into a number of parts.
Companies promoting MPEG-4 compatibility do not always clearly state which "part"
level compatibility they are referring to. The key parts to be aware of are MPEG-4
part 2 (including Advanced Simple Profile, used by codecs such as DivX, Xvid,
Nero Digital and 3ivx and by Quicktime 6) and MPEG-4 part 10 (MPEG-4 AVC/H.264
or Advanced Video Coding, used by the x264 encoder, by Nero Digital AVC, by Quicktime
7, and by high-definition video media like Blu-ray Disc).
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
