Convert MJPG to WMV

MJPG to WMV Conversion Software converts MJPG files to WMV. The software is an easy to use and professional video converter. MJPG 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 MOV, H.264, iPad, Xvid, MKV, PSP, Creative ZEN, PS3, etc. It could convert MJPG to 3GP, VOB to WebM, DVD to FLV, MPG to Xvid, EVO to BlackBerry, VID to OGV, and so on.

MJPG to WMV Conversion Software supports batch conversion that enables you convert bulk MJPG files to WMV at a time. The software is full compatible with 32-bit and 64-bit Windows 10/8/7/Vista/XP/2000.

MJPG to WMV Conversion Software is compatible with Windows 10/8/7/Vista/XP/2008/2003/2000

What is MJPG?
MJPG stands for Motion JPEG. MJPG is an informal name for multimedia formats where each video frame or interlaced field of a digital video sequence is separately compressed as a JPEG image. It is often used in mobile appliances such as digital cameras.

MJPG is frequently used in non-linear video editing systems. Reproduction of this format at full speed requires fast JPEG decoding capability.

MJPG is also commonly used by IP based video cameras via HTTP streams by using the multipart/x-mixed-replace content type or via RTP.

The PlayStation game console has integrated MJPGdecompression hardware in order to play in-game FMV sequences. The Playstation Portable handheld game console can play MJPG from the Memory Stick Pro Duo under the .avi extension with a resolution of 480x272. It can also record clips in MJPG via its Go!Cam camera. Nintendo's Wii game console can play MJPG-encoded videos off an SD card using its Photo Channel. The SanDisk Sansa e200 and the Zen V digital audio players play short MJPG videos.

The AMV video format, common on cheap "MP4" players, is a modified version of MJPG.

In addition to portable players (which are mainly "consumers" of the video), some digital cameras can create such videos. For instance:

in August 2008, Nikon announced the D90, the first D-SLR to record video. The format used is MJPG. The D90 uses three different motion JPEG formats: 320x216 pixels, 640x424 pixels and 1280x720 pixels.
in June 2009, Pentax announced that the upcoming K7 camera will use MJPG in resolutions 640x416, 1280x720, and 1536x1024. The data rate for the MJPG files created can be up to 74 Mbit/s.

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 and 1080p.
