Convert DAT 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.
DAT to JPG/JPEG Converter Software converts DAT to JPG/JPEG
sequence files. So, you could get every frame image of DAT 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 iPhone, WMV, MKA, DivX, PPM image sequence, MPA, Windows Phone,
etc. The software could convert M2TS to Android Tablet, 3G2 to VOB (DVD Video), DVR-MS to Windows Phone, 3G2 to M4V, H263 to CAF (Core Audio Format), and so on.
DAT to JPG/JPEG Software supports batch conversion and, is compatible
with Windows 10/8/7/Vista/XP/2000.
What is DAT?
DAT (DATA) is a file format that stores video streams and are highly compatible
with Video CD (VCD) players. The disc format is also supported using Windows
Media Player Classic variations and VLC Media Player both support VCDs
natively. In a VCD, the audio and video streams are multiplexed in an MPEG
program stream (MPEG-PS) container. The VCD standard was created in 1993
by Sony, Philips, Matsushita, and JVC and is referred to as the White Book
standard. Though supplanted by the two aforementioned formats, VCDs are
still popular, particularly in the low cost market. 352x240 (or SIF) resolution
was chosen because it is half the vertical, and half the horizontal resolution
of NTSC video. Video specifications: Codec: MPEG-1; Resolution: 352x240
(NTSC), 352x288 (PAL/SECAM); Aspect Ratio: 4:3 (NTSC), 4:3 (PAL/SECAM);
Framerate: 29.97 or 23.976 frames per second (NTSC), 25 frames per second
(PAL/SECAM); Bitrate: 1,150 kilobits per second; Rate Control: constant
bitrate. By compressing both the video and audio streams, a VCD is able
to hold 74 minutes of picture and sound information, nearly the same duration
as a standard 79 minute audio CD. Video CDs are not popular in the US,
Canada and Europe, so its support is limited among mainstream software.
Windows Media Player prior to version 9 and QuickTime Player do not support
playing VCD directly, though they can play the .DAT files (stored under
MPEGAV for video and audio data) reliably, and plugins were available.
Video CD players should play the video from the DAT files without having
to open the files manually. Similarly, the audio frequency range is limited
to those sounds most clearly heard by the human ear.
What is JPG?
Compressed image format standardized by the Joint Photographic Experts
Group (JPEG); commonly used for storing digital photos since the format
supports up to 24-bit color; therefore, most digital cameras save images
as JPG files by default. JPEG 2000 has been published as an ISO standard,
ISO/IEC 15444. As of 2012, JPEG 2000 is not widely supported in web browsers,
and hence is not generally used on the Internet. Together with the Graphic
Interchange Format (GIF) and Portable Network Graphics (PNG) file formats,
the JPEG is one of the image file formats supported on the World Wide Web,
usually with the file suffix of ".jpg". You can create a progressive
JPEG that is similar to an interlaced GIF. ISO/IEC 15444-12 is identical
with ISO/IEC 14496-12 (MPEG-4 Part 12) and it defines ISO base media file
format. For example, Motion JPEG 2000 file format, MP4 file format or 3GP
file format are also based on this ISO base media file format. Image files
that employ JPEG compression are commonly called "JPEG files",
and are stored in variants of the JIF image format. Most image capture
devices (such as digital cameras) that output JPEG are actually creating
files in the Exif format, the format that the camera industry has standardized
on for metadata interchange. On the other hand, since the Exif standard
does not allow color profiles, most image editing software stores JPEG
in JFIF format, and also include the APP1 segment from the Exif file to
include the metadata in an almost-compliant way; the JFIF standard is interpreted
somewhat flexibly. The image is split into blocks of 8*8 pixels, and for
each block, each of the Y, CB, and CR data undergoes the Discrete Cosine
Transform (DCT), which was developed in 1974 by N. Ahmed, T. Natarajan
and K. R. Rao. A DCT is similar to a Fourier transform in the sense that
it produces a kind of spatial frequency spectrum.
