Convert H264 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".
H264 to PNG Converter Software converts H264 to PNG sequence files.
The software captures every frame of H264 video clips, and then exports the
frames to a serial of separated PNG files. You can also convert H264 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 FLV, 3G2, M4V, MPG, H.264, 3GP, iPad, etc.
The software could convert 3GP to MMF, RM to PPM image sequence, AVI to SPX (Speex), 3G2 to DivX, M2TS to M4B (MPEG-4 audiobook),
and so on.
H264 to PNG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is H264?
The H.264 video codec supports high definition video and audio and it can
be used with many different file formats such as MP4, MPEG, AVI and MOV
to name just a few. A specific decoder decodes at least one, but not necessarily
all profiles. The decoder specification describes which of the profiles
can be decoded. For example, H.264 has been reported to give the same Digital
Satellite TV quality as current MPEG-2 implementations with less than half
the bitrate, with current MPEG-2 implementations working at around 3.5
Mbit/s and H.264 at only 1.5 Mbit/s. To ensure compatibility and problem-free
adoption of H.264/AVC, many standards bodies have amended or added to their
video-related standards so that users of these standards can employ H.264/AVC.
The product of this partnership effort is known as the Joint Video Team
(JVT). An encoder converts video into a compressed format and a decoder
converts compressed video back into an uncompressed format. From January
2005 to November 2007, the JVT was working on an extension of H.264/AVC
towards scalability by an Annex (G) called Scalable Video Coding (SVC).
Developed for use in high definition systems such as HDTV, Blu-ray and
HD DVD as well as low resolution portable devices such as Sony's PSP and
Apple's iPod, H.264 offers better quality at lower file sizes than both
MPEG-2 and MPEG-4 ASP (DivX or XviD). The final drafting work on the first
version of the standard was completed in May 2003. On the other hand, for
spatial and quality bitstream scalability (i.e. the presence of a sub-bitstream
with lower spatial resolution/quality than the main bitstream), the NAL
(Network Abstraction Layer) is removed from the bitstream when deriving
the sub-bitstream.
What is PNG?
PNG is a popular digital image format whose compression algorithm does
not degrade the quality of the file. PNG, like GIF, is capable of transparency,
so it is used frequently in web design--though its popularity has not reached
that of the prolific GIF format. True color 24 bit images are one of fifteen
color options in PNG format. Images can be created using color palettes
or 8 bit grayscale. Pixel data with 8 bit values can index into palettes
containing up to 256 colors, and with fewer colors pixel values can be
1, 2 or 4 bits. For specialist requirements PNG also offers 48 bit true
color and 16 bit grayscale. The PNG compression algorithm is one of the
best that can be found. Unlike standard JPEG images, PNG compression involves
no loss of image data, so there is no smudging or blurring. In some cases,
filtering can compress the image data even more. Each horizontal line in
an image can have one of five filter types associated with it. Whether
specifying a filter helps in a particular case depends on the image content.
In most cases the default setting is best ( adaptive filtering ). GIF intrinsically
supports animated images. PNG supports animation only via unofficial extensions
(see the section on animation, above). PNG uses a 2-stage compression process:
pre-compression: filtering (prediction); compression: DEFLATE. JPEG-LS
is a "near-lossless" image format by the Joint Photographic Experts
Group, though far less widely known and supported than the other lossy
JPEG format. It is directly comparable with PNG, and has a standard set
of test images. On the Waterloo Repertoire ColorSet, a standard set of
test images (unrelated to the JPEG-LS conformance test set), JPEG-LS generally
performs better than PNG, by 10-15%, but on some images PNG performs substantially
better, on the order of 50-75%. Thus, if both of these formats are options
and file size is an important criterion, they should both be considered,
depending on the image.
