Convert OGV 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".
OGV to PNG Converter Software converts OGV to PNG sequence files.
The software captures every frame of OGV video clips, and then exports the
frames to a serial of separated PNG files. You can also convert OGV 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 MP2, Android Phone, iPhone, 3G2, Windows Phone, TS, PPM image sequence, etc.
The software could convert RM to iPhone, AVI to OGG Vorbis, WebM to WebM (VP8), AVI to WMV, DVR-MS to MP3,
and so on.
OGV to PNG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is OGV?
OGV, or Ogg Vorbis Video, is an open-source format, which means anyone
can freely modify the format without having to worry about copyright. It
began as a 2006 Google Summer of Code project, and it has been developed
on both the Nios II and LEON processors. Theora is well established as
a video format in open source applications, and is the format used for
Wikipedia's video content. However, the proposed adoption of Theora as
part of the baseline video support in HTML5 resulted in controversy. Theora
is a free and open video compression format from the Xiph.org Foundation.
The predecessor On2 TrueMotion VP3 was originally a proprietary and patent-encumbered
video codec developed by On2 Technologies. Theora is an open and royalty-free
lossy video compression technology being developed by the Xiph.Org Foundation
as part of their Ogg project. Based upon On2 Technologies' VP3 codec, Theora
competes with MPEG-4, WMV, and similar low-bitrate video compression schemes.
As originally recommended by HTML 5, these browsers support Theora when
embedded by the video element: Mozilla Firefox, Google Chrome, SeaMonkey,
Konqueror, Opera, WebKitGTK+, and Midori. Theora also does not support
interlacing, or bit-depths larger than 8 bits per component. VP3.1 was
introduced in May 2000 and followed three months later by the VP3.2 release,
which is the basis for Theora. Theora scales from postage stamp to HD resolution,
and is considered particularly competitive at low bitrates. It is in the
same class as MPEG-4/DiVX, and like the Vorbis audio codec it has lots
of room for improvement as encoder technology develops. Xiph.Org, the developers
of the OGV format, provide a DirectShow codec pack that enables software
developers to include support for OGV files in both open-source and commercial
What is PNG?
Portable Network Graphics (PNG) format has a "lossless" compression
scheme. This type of format does not lose any data that refers to the image
during saving. This translates to a clearer, more realistic representation
of the illustration when viewing. PNG supports up to 8 pixel bits and has
full-range transparency and interlacing that is two-dimensional. Because
of this, upon opening, the image will load completely--initially as a low
resolution image--and then "build up" its full quality resolution
potential on the screen. In addition to the now-obsolete benefit of being
royalty free, the PNG image format has a number of technical advantages
over the GIF format. The original PNG specification was authored by an
ad-hoc group of computer graphics experts and enthusiasts. Discussions
and decisions about the format were done exclusively via email. Because
JPEG uses lossy compression, it suffers from generation loss, where repeatedly
encoding and decoding an image progressively loses information and degrades
the image. Because PNG is lossless, it is a suitable format for storing
images to be edited. While PNG is reasonably efficient when compressing
photographic images, there are lossless compression formats designed specifically
for photographic images, lossless JPEG 2000 and Adobe DNG (Digital negative)
for example. However these formats are either not widely supported or proprietary.
An image can be saved into JPEG format for distribution so that the single
pass of JPEG encoding will not noticeably degrade the image. 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.
