Convert WebM to PNG Sequence
PNG (Portable Network Graphics) is a bitmapped image
format that employs lossless data compression. PNG was created to improve upon
and replace GIF (Graphics Interchange Format) as an image-file format not requiring
a patent license. The initialism PNG can also be interpreted as a recursive initialism
for "PNG's Not GIF".
WebM to PNG Converter Software converts WebM to PNG sequence files.
The software captures every frame of WebM video clips, and then exports the
frames to a serial of separated PNG files. You can also convert WebM to other
image formats such as BMP, JPG, and TIFF.
And, you can set output frame rate, and output image size with the software. The
output PNG files look something like this.
The software is also a video and audio converter that supports common formats
and portable devices such as Windows Phone, 3GP, SWF, MMF, CAF (Core Audio Format), 3G2, MP2, etc.
The software could convert M2TS to iPod, VOB to MKA, 3G2 to Xvid, DVD to PPM image sequence, 3GP to Android Tablet,
and so on.
WebM to PNG 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. The project releases WebM related software
under a BSD license and all users are granted a worldwide, non-exclusive,
no-charge, royalty-free patent license. Despite this, some in the industry
have called upon Google to provide indemnification against patent suits.
Logitech is planning to use WebM as part of a video calling service. 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. Google
acquired ON2, the original developer of VP8 technology. VP8 is now an open
and free technology. WebM features: Low computational footprint to enable
playback on any device, including low-power netbooks, handhelds, tablets,
etc.; Simple container format; Highest quality real-time video delivery;
Click and encode. Minimal codec profiles and sub-options. When possible,
let the encoder make the tough choices. WebM Project licenses VP8 hardware
accelerators (RTL IP) to semiconductor companies for 1080p encoding and
decoding at zero cost. AMD, ARM and Broadcom have announced support for
hardware acceleration of the WebM format. Intel is also considering hardware-based
acceleration for WebM in its Atom-based TV chips if the format gains popularity.
Qualcomm and Texas Instruments have announced support, with native support
coming to the TI OMAP processor. Chip&Media have announced a fully
hardware decoder for VP8 that can decode full HD resolution VP8 streams
at 60 frames per second.
What is PNG?
Portable Network Graphics (PNG, pronounced "PING") is a format
that employs lossless data compression. It was developed as the next format
to the Graphics Interchange Format (GIF), which was patented by Unisys
and Compuserve. PNG supports a 24-bit Red Green Blue palette for the Internet
and was approved by the Internet Steering Group in 1996. Image file stored
in the Portable Network Graphic (PNG) format; contains a bitmap of indexed
colors and uses lossless compression, similar to a .GIF file but without
copyright limitations; commonly used to store graphics for Web images.
The PNG format allows three different styles of transparency: one for indexed
color images and two for greyscale or truecolor images. PNG gives a much
wider range of transparency options than GIF, including alpha channel transparency.
This specification defines an Internet Media Type image/png. Unlike the
GIF89a, the PNG format doesn't support animation since it can't contain
multiple images. The PNG is described as "extensible," however.
Software houses will be able to develop variations of PNG that can contain
multiple, scriptable images. PNG file size can vary significantly depending
on how it is encoded and compressed; this is discussed and a number of
tips are given in PNG: The Definitive Guide. The only limitation of PNG
as compared to GIF is that it does not support animations. Unlike the JPEG
and GIF formats, the PNG format supports an alpha channel, or the "RGBA"
color space. The alpha channel is added to the three standard color channels
(red, green, and blue, or RGB) and provides 256 levels of transparency.
JPEG images do not support transparent pixels and GIF images only support
completely transparent (not partially opaque) pixels. Therefore, the PNG
format allows Web developers and icon designers to fade an image to a transparent
background rather than a specific color. A PNG with an alpha channel can
be placed on any color background and maintain its original appearance,
even around the edges.
