Convert DVR-MS 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.
DVR-MS to JPG/JPEG Converter Software converts DVR-MS to JPG/JPEG
sequence files. So, you could get every frame image of DVR-MS 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 VOC, WMV, DV, SPX (Speex), M4R (iPhone ringtone), CAF (Core Audio Format), MP2,
etc. The software could convert FLV to WMV, RM to Windows Phone, RM to M4B (MPEG-4 audiobook), WebM to M4V, AVI to OGM, and so on.
DVR-MS to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is DVR-MS?
DVR-MS (Microsoft Digital Video Recording) is a proprietary video and audio
file format, developed by Microsoft. The extension was originally used
by Zach Johnson who at the time was a developer for the television recording
engine for Microsoft Windows XP Media Center Edition. They can also played
within Windows Media Center, which is included with Windows Vista Home
Premium and Ultimate editions. The files are used with Microsoft's Windows
Media Center, which can be used as a DVR to view and capture TV shows through
your computer. An update is available for Windows Media Player 11 in Windows
Vista to add playback support for WTV. Unprotected DVR-MS files (files
not marked in this way) can be played back on any device running Windows
XP with Service Pack 1 or later Windows operating systems, hotfix 810243
for Windows XP RTM (which adds DVR-MS support to DirectShow), and on Windows
Mobile 6. The format extends these standards by including metadata about
the content and digital rights management. Some early freeware applications
which convert the files can be found from third parties such as at The
Green Button. DVR-MS is the file type used for video that has been captured
from television through a digital video recorder. A simple registry tweak/hack
also exists for allowing the Windows XP version of Windows Movie Maker
to natively import/edit DVR-MS files. The DVR feature of Windows XP Media
Center Edition, Windows Vista and the Windows 7 version of Windows Media
Center create files in this format. Zach Johnson, a developer for Microsoft
Windows XP, was the first to use the DVR-MS file extension. When you use
Media Center to capture television footage, the video files are saved in
the DVR MS format.
What is JPG?
JPEG (usually pronounced JAY-pehg) is also a term for any graphic image
file produced by using a JPEG standard. A JPEG file is created by choosing
from a range of compression qualities (actually, from one of a suite of
compression algorithms). The JPG file is wonderfully small, often compressed
to perhaps only 1/10 of the size of the original data, which is a good
thing when modems are involved. However, this fantastic compression efficiency
comes with a high price. JPG modifies the image pixel data (color values)
to be more convenient for its compression method. Tiny detail that doesn't
compress well (minor color changes) can be ignored (not retained). This
allows amazing size reductions on the remainder, but when we open the file
and expand the data to access it again, it is no longer the same data as
before. This lost data is like lost purity or integrity. It can vary in
degree, it can be fairly good, but it is always unrecoverable corruption
of the data. This makes JPG be quite different from all the other usual
file format choices. This will sound preachy, but if your use is critical,
you need a really good reason to use JPG. JPEG 2000 is the latest series
of standards from the JPEG committee. The original standard for digital
images (IS 10918-1, popularly referred to as JPEG) was developed 15 years
ago, and with the major increase in computer technology since them, and
lots of research, it was felt to be time for a new standard capable of
handling many more aspects than simply making the digital image files as
small as possible. It is difficult to describe the JPG quality losses,
except by seeing an example image (next page). JPG does not discard pixels.
Instead it changes the color detail of some pixels in an abstract mathematical
way. JPG is mathematically complex and requires considerable CPU processing
power to decompress an image. JPG also allows several parameters, and programs
don't all use the same JPG rules. Programs vary, some programs take shortcuts
to load JPG faster but with less quality (browsers for example), and other
programs load JPG slower with better quality. Final image quality can depend
on the image details, on the degree of compression, on the method used
by the compressing JPG program, and on the method used by the viewing JPG
program.
