About DVD
DVD generally stands for Digital Video Disc or Digital Versatile Disc.
DVD, providing large space and interactive content, has been widely used
as data storage of video, audio, games, presentation, and so on. For
DVDs with movies, there are three kinds of files under the VIDEO_TS
folder, i.e. VOB, IFO, and BUP files. A VOB contains data for video
(generally MPEG-2), audio and subtitles. IFO Files contain the data for
player navigation, such as the start of a chapter, the control of
subtitle, and so on. BUP files are just backup files of the IFOs.

About AVI
AVI stands for Audio Video Interleave. Defined by Microsoft, it can
work as a container to be embedded with different codec, such as DivX,
XviD, etc. The AVI video generally brings high quality, but occupies
larger disk space. It is suitable for further video editing.

'Pavtube DVD Ripper' (http://www.pavtube.com/dvd_ripper/) offer several
options for AVI with uncompressed codec and less compressed codec. The
uncompressed codec is available for the profile "Losseless uncompressed
avi". The profile is set with recommended settings, and you can also
change the output format by clicking the "Settings" button. There are
six video codec for uncompressed AVI: BGR24, RGB555, YUY2, UYVY, and
RGBA32.

RGBA32 completely stores 4 color components: R (Red), G (Green), B
(Blue), and A (Alpha). If a video does not include alpha channel, the
alpha channel here will not come into effect.
BGR24 completely stores 3 color components: RGB. If a video does not
include alpha channel, the effect of RGBA32 is the same as BGR24, but
the output file with RGBA32 will be a quarter larger than that with
BGR24. If a video includes alpha channel, but is encoded with BGR24, the
alpha channel will be lost, i.e. there is no transparency.
RGB555 does not store all the 3 color components: RGB. There are 5 bits
for each color component (8 bits for that of RGBA32 and BGR24). It does
not display the gradual color change effectively.
YUY2 is different from RGB series. It uses YUV color space with 3
components: Y (luminance component),
U (chrominance component), V (chrominance component), not RGB. The file
with YUV2 is a bit worse than that with RGBA32 or BGR24, but better than
RGB555.
UYVY is the same as YUY2, but the storing sequence is different. The
file with UYVY is the same as that with YUY2.

The output quality differs slightly. The following comparison works as
a reference.
RGBA32 >= BGR24 > YUY2 = UYVY > RGB555

Please choose the codec according to the source file. You'd better
choose BGR24 if there is no alpha channel with the video, as the effect
is the same as that with RGBA32. Choose RGBA32 if there is alpha
channel.

There are 5 profiles for AVI with less compressed codec, AVI ? Audio
Video Interleaved, XVID Video, DIVX Video, AVI with DV Codec, Creative
Zen Player Video.

The profile for Creative Zen Player Video is particular for Creative
Zen with preset image dimension and video bit rate. You can choose the
codec from DivX and XviD.
DV AVI can be transferred to digital camcorder.
The video codec: MS MPEG4 V3, MS MPEG4 V2, and MJPEG here are for "AVI
? Audio Video Interleaved".

The compressed codec in Pavtube DVD Ripper are based on YUV color
space. Generally speaking, with the same bit rate, the quality of the
compressed codec shows up the following
H.264 >= XVID > MS MPEG4 V3 / V2 > MJPEG
DivX is a commercial codec, and the ripper uses the free DivX 3.

Please note that you shall install related codec if you want to play
the output AVI on computer, such as DivX, XviD.

You change also change other settings like Bit Rate, Video Size, Frame
Rate, etc. to make it work as what you expect. Click on "Save as", if
you want to save the format for future references with the parameters
you set. Click the "OK" button, and the format will be applied to all
the files. Click "Reset" to get the default parameters of the profile.

output AVI files. Pavtube DVD Ripper also offers other settings for you
