Convert M4V 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.
M4V to JPG/JPEG Converter Software converts M4V to JPG/JPEG
sequence files. So, you could get every frame image of M4V 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 MP2, OGM, AIFF, MPA, SWF, OGG, MPG,
etc. The software could convert WebM to WAV, OGG to ALAC (Apple Lossless), FLV to Xvid, AVI to PNG image sequence, 3GP to DivX, and so on.
M4V to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is M4V?
M4V files are digital videos that have been especially compressed for playback
on iPod and iPhone devices. It is also playable by the Android operating
system with its video player. MPEG-4 is a multimedia container format.
To play a protected M4V file, your computer must be authorized (using iTunes)
with the account that was used to purchase the video. There are two definitions
for the term M4V. The first is that raw MPEG-4 Visual bitstreams are named
.m4v. The second, and much more likely, is that you have legally downloaded
a video file from the Apple iTunes store and it has the M4V extension.
These files can be movies, TV shows or music videos and all will include
Apple's FairPlay DRM copyright protection. The M4V video file can be embedded
on a website in HTML code by using the <video> tag. This tag, introduced
in HTML5, makes it simple to embed an M4V file. Although the format is
used by the Apple iTunes Store to distribute video, third-party videos
can be encoded as M4V files since it is an open format. M4V can be read
by all Mac products, like iPhone and iPod Touch, but it is not widely readable
in non-Mac devices and programs. It is most commonly used to store digital
audio and digital video streams, but can also be used to store other data
such as subtitles and still images. The copyright of M4V files may be protected
by using Apple's FairPlay DRM copyright protection. Under QuickTime, M4V
video with FairPlay attached to it is identified as AVC0 Media. M4V files
are video files that are most commonly associated with Apple iTunes. If
a file is protected, unauthorized users may be unable to view, open, edit,
delete or otherwise access the file.
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. Another important aspect of JPEG is that decoders
can trade off decoding speed against image quality, by using fast but inaccurate
approximations to the required calculations. Some viewers obtain remarkable
speedups in this way. (Encoders can also trade accuracy for speed, but
there's usually less reason to make such a sacrifice when writing a file.)
A number of alterations to a JPEG image can be performed losslessly (that
is, without recompression and the associated quality loss) as long as the
image size is a multiple of 1 MCU block (Minimum Coded Unit) (usually 16
pixels in both directions, for 4:2:0 chroma subsampling). Utilities that
implement this include jpegtran, with user interface Jpegcrop, and the
JPG_TRANSFORM plugin to IrfanView. 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.
JPEG works well when compressing full color or grayscale images. The human
eye has difficulty seeing the distortion in a JPEG image. Thus the image
looks almost exactly like the original, even though some of the image data
has been lost. JPEGs store information in 24-bit color depth, which can
contain as many as 16 million colors. GIF, by comparison, is an 8-bit image
compression format, which contains just 256 colors. By saving a complex,
24-bit image as a JPEG, there is considerably less distortion than if it
were saved as a GIF. The smaller the image is when it is viewed, the less
the viewer will be able to see any JPEG distortion.
