Convert WebM 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.
WebM to JPG/JPEG Converter Software converts WebM to JPG/JPEG
sequence files. So, you could get every frame image of WebM 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
The software also supports other formats and portable devices such as M4B (MPEG-4 audiobook), FLAC, Windows Phone, Xvid, Android Tablet, MMF, MP2,
etc. The software could convert XVID to PPM image sequence, RM to MKV, RM to 3G2, M2TS to TS, DAT to H.264, and so on.
WebM to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is WebM?
WebM defines the file container structure, video and audio formats. WebM
files consist of video streams compressed with the VP8 video codec and
audio streams compressed with the Vorbis audio codec. The WebM file structure
is based on the Matroska container. On 19 January 2011, the Free Software
Foundation announced its official support for the WebM project. Logitech
is planning to use WebM as part of a video calling service. In response,
the WebM Project decoupled patents from copyright, offering the code under
a standard BSD license and patents under a separate grant. The Free Software
Foundation, which maintains the Free Software Definition, has given its
endorsement for WebM and VP8 and considers the software's license to be
compatible with the GNU General Public License. In mid-2010, Simon Phipps,
a board member for the Open Source Initiative, expressed doubts as to whether
the original WebM license was an open-source license, since it had not
been submitted to the OSI for approval. VP8 is a highly efficient video
compression technology that was developed by On2 Technologies. Google acquired
On2 in February, 2010. For more information, see the -VP8 Video Codec"
section below. A WebM file consists of VP8 video and Vorbis audio streams,
in a container based on a profile of Matroska. Some video codecs require
content distributors and manufacturers to pay patent royalties to use the
intellectual property within the codec. WebM and the codecs it supports
(VP8 video and Vorbis audio) require no royalty payments of any kind. You
can do whatever you want with the WebM code without owing money to anybody.
Adobe Systems announced that its Flash Player will be updated to support
WebM, but no exact date was specified for its addition.
What is JPG?
Compressed image format standardized by the Joint Photographic Experts
Group (JPEG); commonly used for storing digital photos since the format
supports up to 24-bit color; therefore, most digital cameras save images
as JPG files by default. Blocks can be rotated in 90 degree increments,
flipped in the horizontal, vertical and diagonal axes and moved about in
the image. Not all blocks from the original image need to be used in the
modified one. Due to the densities of color- and brightness-sensitive receptors
in the human eye, humans can see considerably more fine detail in the brightness
of an image (the Y' component) than in the hue and color saturation of
an image (the Cb and Cr components). Using this knowledge, encoders can
be designed to compress images more efficiently. Entropy coding is a special
form of lossless data compression. It involves arranging the image components
in a "zigzag" order employing run-length encoding (RLE) algorithm
that groups similar frequencies together, inserting length coding zeros,
and then using Huffman coding on what is left. The PNG (Portable Network
Graphics) format is still more space-efficient in the case of images with
many pixels of the same color, such as diagrams, and supports special compression
features that JPEG 2000 does not. Motion JPEG 2000 (often referenced as
MJ2 or MJP2) also is under consideration as a digital archival format by
the Library of Congress. It is an open ISO standard and an advanced update
to MJPEG (or MJ), which was based on the legacy JPEG format. Unlike common
video formats, such as MPEG-4 Part 2, WMV, and H.264, MJ2 does not employ
temporal or inter-frame compression. Instead, each frame is an independent
entity encoded by either a lossy or lossless variant of JPEG 2000. Its
physical structure does not depend on time ordering, but it does employ
a separate profile to complement the data. For audio, it supports LPCM
encoding, as well as various MPEG-4 variants, as "raw" or complement
