Convert WMV to JPG/JPEG Sequence
|
JPG/JPEG is a commonly used method of lossy compression
for digital photography (image). The degree of compression can be adjusted, allowing
a selectable tradeoff between storage size and image quality. JPEG typically achieves
10:1 compression with little perceptible loss in image quality.
WMV to JPG/JPEG Converter Software converts WMV to JPG/JPEG
sequence files. So, you could get every frame image of WMV in
JPG/JPEG format. You can also set output frame rate and JPG/JPEG resolution in
the software. The output JPG/JPEG files look something like the following screen
shot.
The software also supports other formats and portable devices such as OGG, DV, MP2, WebM (VP8), Android Tablet, MP3, OGM,
etc. The software could convert AVI to AIFF, MPEG to SWF, MOV to DV, MP4 to Android Tablet, MPEG to 3G2, and so on.
WMV to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is WMV?
A WMV file is the name commonly used for Windows Media Video files, which
are developed by Microsoft and compatible with all Windows operating systems.
The Microsoft Zune, Xbox 360, Windows Mobile-powered devices with Windows
Media Player, as well as many uncertified devices, support the codec. This
file is also found as a video/audio file on the Xbox. A number of programs
capture this file extension. 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. Creating WMV files is simple in Windows'
standard video-editing software Movie Maker. Movie Maker works only on
Windows-based systems, so if you would like to create WMVs on a Mac system,
you'll have to create a different movie file type first and convert to
WMV. The other formats, such as WMV Screen and WMV Image, cater for specialized
content. The technology was considered a stepping stone to true high definition
optical disc formats (HD DVD and Blu-ray Disc) and Microsoft never intended
the discs to be played on anything but personal computers. 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. Windows Media Format 11 adds support for HD video up to 1080P.
WMF 11 runs only on Windows XP and Vista. The file extension .WMV typically
describes ASF files that use Windows Media Video codecs. The loss of the
ability to restore licenses for WMV files in the Windows Media Player 11
was not positively received. In addition, the Microsoft Zune does not support
the standard Windows Media DRM system, rendering protected WMV files unplayable.
What is JPG?
JPEG stands for Joint Photographic Experts Group. It is a standard method
of compressing photographic images. We also call JPEG the file format which
employs this compression. Regardless of that selected image size in pixels,
the camera menu will also offer a smaller file size choice in bytes, related
to quality, via JPG file compression. This menu will offer a best quality
setting which is the largest file, and maybe intermediate sizes, and a
smallest but worst quality choice. The best (largest) JPG file size will
still contain JPG artifacts, but very mild, essentially undetectable, vastly
better than the smallest file choice. Even better, some cameras also offer
a RAW or TIF format to bypass JPG problems all together. These images may
be large, but memory cards are becoming less expensive, and larger or multiple
cards are by far the best quality solution. Many JPEG files embed an ICC
color profile (color space). Commonly used color profiles include sRGB
and Adobe RGB. Because these color spaces use a non-linear transformation,
the dynamic range of an 8-bit JPEG file is about 11 stops. The resolution
of the chroma data is reduced, usually by a factor of 2. This reflects
the fact that the eye is less sensitive to fine color details than to fine
brightness details. After subsampling, each channel must be split into
8*8 blocks. Depending on chroma subsampling, this yields (Minimum Coded
Unit) MCU blocks of size 8*8 (4:4:4 - no subsampling), 16*8 (4:2:2), or
most commonly 16*16 (4:2:0). In video compression MCUs are called macroblocks.
The resulting compression ratio can be varied according to need by being
more or less aggressive in the divisors used in the quantization phase.
Ten to one compression usually results in an image that cannot be distinguished
by eye from the original. 100 to one compression is usually possible, but
will look distinctly artifacted compared to the original. The appropriate
level of compression depends on the use to which the image will be put.
