Convert H263 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.
H263 to JPG/JPEG Converter Software converts H263 to JPG/JPEG
sequence files. So, you could get every frame image of H263 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 Xvid, SWF, OGV, PPM image sequence, MP4, MP3, Android Tablet,
etc. The software could convert DAT to AC3, OGV to AIFF, DVD to FLAC, FLV to VCD, OGV to OGG Vorbis, and so on.
H263 to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is H263?
H.263 is a video codec standard originally designed as a low-bitrate compressed
format for videoconferencing. Its first version was completed in 1995 and
provided a suitable replacement for H.261 at all bitrates. The next enhanced
codec developed by ITU-T VCEG (in partnership with MPEG) after H.263 is
the H.264 standard, also known as AVC and MPEG-4 part 10. Since the original
ratification of H.263 in March 1996 (approving a document that was produced
in November 1995), there have been two subsequent additions which improved
on the original codec by additional optional annexes (extensions). For
example, the H.263v2 added a deblocking filter via Annex J. H.263 is a
standard video-conferencing codec. As such, it is optimized for low data
rates and relatively low motion. 4CIF and 16CIF are 4 and 16 times the
resolution of CIF respectively. H.263 supports five resolutions(CIF (Common
Interchange Format), QCIF (Quarter Common Interchange Format), SQCIF, 4CIF
and 16CIF). The original version of the RealVideo codec was based on H263
video up until the release of RealVideo 8. It has replaced H.261 for video
conferencing in most applications and also dominates Internet video streaming
today. H.263 is a provisional ITU-T standard, it is due to be published
sometime in 1995/1996. The coding algorithm of H.263 is similar to that
used by H.261, however with some improvements and changes to improve performance
and error recovery. H.263 has since found many applications on the internet:
much Flash Video content (as used on sites such as YouTube, Google Video,
MySpace, etc.) used to be encoded in Sorenson Spark format (an incomplete
implementation of H.263), though many sites now use VP6 or H.264 encoding.
What is JPG?
Standard computer file format for storing graphic images in a compressed
form for general use. JPEG images are compressed using a mathematical algorithm.
A variety of encoding processes can be used, depending on whether the user's
goal is the highest quality of image (lossless) or smallest file size (lossy).
The JPEG and GIF formats are the most commonly used graphics formats on
the Internet for lossy and lossless data compression, respectively. A simple
or "baseline" JPEG file is stored as one top-to-bottom scan of
the image. Progressive JPEG divides the file into a series of scans. The
first scan shows the image at the equivalent of a very low quality setting,
and therefore it takes very little space. Making image files smaller is
a win for transmitting files across networks and for archiving libraries
of images. Being able to compress a 2 Mbyte full-color file down to, say,
100 Kbytes makes a big difference in disk space and transmission time!
And JPEG can easily provide 20:1 compression of full-color data. If you
are comparing GIF and JPEG, the size ratio is usually more like 4:1. On
the other hand, JPEG may not be as well suited for line drawings and other
textual or iconic graphics, where the sharp contrasts between adjacent
pixels can cause noticeable artifacts. Such images may be better saved
in a lossless graphics format such as TIFF, GIF, PNG, or a raw image format.
The JPEG standard actually includes a lossless coding mode, but that mode
is not supported in most products. The file extensions for this format
are .JPEG, .JFIF, .JPG, OR .JPE although .JPG is the most common on all
platforms. Regular JPEG is "lossy", meaning that the image you
get out of decompression isn't quite identical to what you originally put
in. The algorithm achieves much of its compression by exploiting known
limitations of the human eye, notably the fact that small color details
aren't perceived as well as small details of light-and-dark. Thus, JPEG
is intended for compressing images that will be looked at by humans. If
you plan to machine-analyze your images, the small errors introduced by
JPEG may be a problem for you, even if they are invisible to the eye. The
JPEG standard includes a separate lossless mode, but it is rarely used
and does not give nearly as much compression as the lossy mode.
