DVD ( Digital Versatile Disc ) is a newer version of compact disk ( CD ). DVD
has the same physical dimension of a CD with a data density about 8 times ( 4.7
GB ) of a CD ( 700 MB ). Furthermore, DVD could have two layers of digital
information on one side. A double sided, double layered DVD has a total of 18
GB data capacity. DVD video ( we usually just call it DVD ) is a standard format
for videos on a DVD. Videos are digitized and compressed into MPEG-2 data
stream ( MPG file ), at a variable bit rate ( 9.8Mbit/s max. for video +
audio, sampling at 48kHz ). The MPG file is then output to a special
format on a DVD along with other control files so that it is compatible with
set top DVD players . The video quality of a DVD , at a resolution of 720
X 480 for NTSC, is better than a Super VHS tape ( with a horizontal
resolution of 400 and 525 scan lines for NTSC system ). A single sided, single
layered DVD could have more than 2 hours of high quality video.
We provide the service of DVD authoring, tape to DVD conversion ( VHS to DVD, 8mm to DVD, Betamax to DVD,
miniDV to DVD, Laser disc to
DVD ) at an
affordable price. There are a few advantages for your videos on DVDs, instead
won't last long, but DVD could last for a long time as long as you don't
could access certain section of a video on a DVD much faster than video on
is much smaller in volume to store compared to a tape.
converted to DVD, you could make many copies of the video without losing
any video quality.
We convert the following kinds of video tapes to DVD: ( NTSC, PAL, or SECAM )
VHS-C and VHS to DVD, ( NTSC only ) super VHS to DVD, ( NTSC or PAL ) Digital8, Hi8,
8mm to DVD, ( NTSC or PAL ) mini DV to DVD, ( NTSC or PAL ) Betamax to DVD, ( NTSC
laser disc to DVD ( Click here
for details ). We also convert Super 8 / 8 mm films or
16 mm films to DVD ( Click here
for details ).
The simple process ( which is also used by most of other
service places and DVD recorders) to transfer video to DVD is real time digitizing and encoding
. The quality of
the encoded video is OK , but not the best . If your video is noisy, or full
of fast motions, there
will be compression artifact in the compressed video because the
microprocessor have difficult time to
do the high quality motion compression in a limited time frame.
All our DVD transfers employ
a better, but
lengthier way to encode the video: capture the video into a DV AVI file
first and then use sophisticate software to do the high quality compression to MPEG-2.
Unlike the simple process, which uses a fixed bit rate, here we use variable
video bit rates for a better quality to file size ratio. It is the process
they used to transfer high quality commercial movies to DVD. This
process takes three times more time than the simple process, but the
quality of the compressed video is noticeably better ( Less compression
artifacts ) , especially in cases of noisy and fast motions original videos.
There are 2 DVD standards : NTSC and PAL. NTSC DVD stores video at 720x480
pixels and 30 fps , while PAL DVD at 720x576 pixels and 25 fps. Normally we
transfer without standard conversions ( it means NTSC video to NTSC DVD and
PAL video to PAL DVD. ) If you choose Option VTD04 in the following table, we will convert
the video standards before MPEG compression and DVD authoring. We use
software conversion with pixels and motions interpolation to ensure high
quality. It takes another 2 hours for every hour of video and that is why we
have to charge extra for it. Please note that most service places use video standards
conversions box to do the job while capturing the video.
It doesn't take extra step and time. But the video has less details and the
motion is not as smooth .

Each DVD conversion includes a menu with a title of your choice and video
entry points ( chapter points ) at approximate equal time intervals. A
thumbnail of the picture at each entry point is displayed in the menu and you
can jump into that video section by selecting that thumbnail or
entering a number on your remote control which is displayed on the
thumbnail. We also include a slim DVD case ( unless you request other sizes of
case ) with printed covers on top (
picture of the main menu ), bottom ( instruction ) and side ( Title of your
VTD03 combines more tapes to the same DVD if the combined length of video is
less than 120 min. For example, if you want to transfer two tapes, 1 hour each, to
a single DVD, the cost would be $25 ( VTD01 + VTD03 )
We could create a custom menu with custom video entry points.
For this extra service, specify the starting time of the video sections
you want to jump in and add $ 1 / link .
