Convert AVI 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.
AVI to JPG/JPEG Converter Software converts AVI to JPG/JPEG
sequence files. So, you could get every frame image of AVI 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
shot.
The software also supports other formats and portable devices such as H.264, VOC, CAF (Core Audio Format), 3G2, MP2, MPG, WebM (VP8),
etc. The software could convert OGV to AIFF, DVD to FLV, MPEG to FLV, DVR-MS to FLAC, M2TS to TS, and so on.
AVI to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is AVI?
Audio Video Interleaved (also Audio Video Interleave), known by its initials
AVI, is a multimedia container format introduced by Microsoft in November
1992 as part of its Video for Windows technology. By way of the RIFF format,
the audio-visual data contained in the "movi" chunk can be encoded
or decoded by software called a codec, which is an abbreviation for (en)coder/decoder.
Upon creation of the file, the codec translates between raw data and the
(compressed) data format used inside the chunk. One of the first terms
a digital video freshman gets to know is codec. However, with the introduction
of DirectShow, AVI became a very flexible and powerful architecture. In
particular, the Indeo CODEC, popular for video compression on PCs, has
not been ported to Mac OS X. AVI and codec are inseparable. AVI is simply
a file format, that doesn't itself define how the video inside the file
was made and how it should be opened. Video container or wrapper format
created by Microsoft; stores video data that may be encoded in a variety
of codecs; typically uses less compression than similar formats such as
.MPEG and .MOV. So now there are hundreds of avi files that look similar
but are completely different inside. There is slight overhead when used
with popular MPEG-4 codecs (Xvid and DivX, for example), increasing file
size more than necessary. The first sub-chunk is identified by the "hdrl"
tag. This sub-chunk is the file header and contains metadata about the
video, such as its width, height and frame rate. It is a special case of
the RIFF (Resource Interchange File Format). For WAV audio files, Broadcast
Wave extensions were designed to standardize post-production metadata,
but an equivalent for AVI files has not emerged.
What is JPG?
JPEG (pronounced "jay-peg") is a standardized image compression
mechanism. JPEG stands for Joint Photographic Experts Group, the original
name of the committee that wrote the standard. JPEG compresses either full-color
or grayscale images, and works best with photographs and artwork. For geometric
line drawings, lettering, cartoons, computer screenshots, and other images
with flat color and sharp borders, the PNG and GIF image formats are usually
preferable. JPEG 2000 images should - if stored as files - be boxed in
the JPEG 2000 file format, where they get the .jp2 extension. The part-2
extension to JPEG 2000, i.e., ISO/IEC 15444-2, also enriches this file
format by including mechanisms for animation or composition of several
code streams into one single image. Images in this extended file-format
use the .jpx extension. A freely available tool called packJPG is based
on the 2007 paper "Improved Redundancy Reduction for JPEG Files."
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. These assertions are tested on a large
set of randomized input images, to handle the worst cases. The former IEEE
1180-1990 standard contained some similar precision requirements. The precision
has a consequence on the implementation of decoders, and it is critical
because some encoding processes (notably used for encoding sequences of
images like MPEG) need to be able to construct, on the encoder side, a
reference decoded image. In order to support 8-bit precision per pixel
component output, dequantization and inverse DCT transforms are typically
implemented with at least 14-bit precision in optimized decoders.
