Convert H263 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".
H263 to PNG Converter Software converts H263 to PNG sequence files.
The software captures every frame of H263 video clips, and then exports the
frames to a serial of separated PNG files. You can also convert H263 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 M4V, 3G2, PPM image sequence, DV, OGM, SPX (Speex), MOV, etc.
The software could convert 3G2 to MP2, MKV to JPG image sequence, MP4 to M4R (iPhone ringtone), DAT to OGM, MOV to Xvid,
and so on.
H263 to PNG 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. The codec was first designed to be utilized
in H.324 based systems (PSTN and other circuit-switched network videoconferencing
and videotelephony), but has since also found use in H.323 (RTP/IP-based
videoconferencing), H.320 (ISDN-based videoconferencing), RTSP (streaming
media) and SIP (Internet conferencing) solutions. It was initially made
to serve H.324 based low-bitrate internet communication systems (videoconferencing
and telephony), but as new extensions were added to the further versions,
H.263 found use in other applications. H.263 is a hybrid of interframe
compression and intraframe transform coding. H.263 is a standard video-conferencing
codec. As such, it is optimized for low data rates and relatively low motion.
SQCIF is approximately half the resolution of QCIF. H.263 uses variable
length coding to be transmit symbols It has replaced H.261 for video conferencing
in most applications and also dominates Internet video streaming today.
4CIF and 16CIF are 4 and 16 times the resolution of CIF respectively. H.263
supports for a limited set of picture sizes: 128x96, 176x144, 352x288,
704x576, and 1408x1152. H.263 enhanced robustness against data loss in
the transmission channel There are now four optional negotiable options
included to improve performance: Unrestricted Motion Vectors, Syntax-based
arithmetic coding, Advance prediction, and forward and backward frame prediction
similar to MPEG called P-B frames. 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.
What is PNG?
PNG is an extensible file format for the lossless, portable, well-compressed
storage of raster images. PNG provides a patent-free replacement for GIF
and can also replace many common uses of TIFF. Indexed-color, grayscale,
and truecolor images are supported, plus an optional alpha channel for
transparency. Sample depths range from 1 to 16 bits per component (up to
48bit images for RGB, or 64bit for RGBA). Tagged Image File Format (TIFF)
is a format that incorporates an extremely wide range of options. While
this makes TIFF useful as a generic format for interchange between professional
image editing applications, it makes adding support for it to applications
a much bigger task and so it has little support in applications not concerned
with image manipulation (such as web browsers). It also means that many
applications can read only a subset of TIFF types, creating more potential
user confusion. Like a GIF, a PNG file is compressed in lossless fashion
(meaning all image information is restored when the file is decompressed
during viewing). A PNG file is not intended to replace the JPEG format,
which is "lossy" but lets the creator make a trade-off between
file size and image quality when the image is compressed. Typically, an
image in a PNG file can be 10 to 30% more compressed than in a GIF format.
A still another advantage of PNG is that it supports three image types
- palette based (2, 4, 16, or 256 color), true color (24-bit and 48-bit),
and gray scale (2, 4, 16, 256 or 65,536 levels of gray). Since PNG is a
lossless format, saving, opening and then resaving the file does not corrupt
the color quality of an image.
