Q1. What type
of video encoder card is Snazzi* III
DVD Creator ?
Answer :
Snazzi* III DVD Creator is the latest
MPEG Compression Card for Professional
quality DVD encoding. It comes with
Stereo Audio, Composite-Video (RCA)
and S-Video (Y/C) inputs and accepts
AV inputs from any camcorder, VCR,
LD/VCD/DVD Players as well as TV source.
The encoded video can be edited and
to be used for burning to a DVD Disc,
VCD/SVCD disc, multimedia CD-ROM compilation
and Video Streaming.
Answer :
MPEG is the de facto compression technology
used to store a very large amount
of digitized AV data into a substantially
smaller file size. Some to the tune
of 200-1000 times. The key advantage
is that despite the high compression
ratio, it is able to reproduce very
high quality output. All DVD movie
and broadcast video make use of this
technology.
Q3.
What is the purpose of our 1394 Instant
DVD product ?
Answer :
1394 Instant DVD is a firewire encoder
developed to suit users who own the
latest DV (or Digital) camcorders.
The video is transferred digitally
from the camcorder into the computer
as well as being encoded digitally
to the DVD format in real-time. This
allows the high quality digital video
to be compressed to a file size about
20% that of the original AVI-DV file
size. The advantage of using 1394
Instant DVD is that you can control
your camcorder functions from your
computer. It also allows direct transfer
of Video in and out of the PC. With
the right software, the unique feature
is in it's ability to transfer video
directly from your DV camcorder to
your DVD Disc. With this you can share
your home video with others using
a regular DVD player or to send to
anyone else who owns a DVD player.
Q4.What is the difference between
linear editing and non-linear editing?
Answer :
For linear editing, it involves editing
directly from one tape to another.
The tape has to be sequentially wound
and rewound to carry out the editing
process. For non-linear editing(NLE),
a video encoder card is used to transfer
the video to PCs hard disk in digital
format which allows the editing process
to be carried out in a randomly accessible
manner. This speeds up the whole editing
process.
Answer :
Desktop Video is utilizing your computer
to create videos. You can use your
computer to overlay titles & graphics,
add sound tracks, control your camcorder,
perform digital video effects, and
perform many computer assisted editing
functions on your videos.
Answer :
Video Encoder Card converts video
from Analogue to digital and at the
same time compresses it to the MPEG
format to be stored into your hard
disk for purpose of editing, streaming,
burning to a VCD/SVCD/DVD or streaming.
You can edit the video and play it
back to tape and display the finished
movie on your computer screen or TV
screen. Top
Q7.
What is a CODEC ?
Answer :
CODEC stands for Compression/Decompression.
It is the method used by video encoders
to digitize the video and store in
hard disk. The most commonly used
CODECs today are DV and MPEG.
Q8.What is the preferred PC processor
speed required for Non-Linear Editing
?
Answer :
The processing speed of PC is important
for determining the rate of render
and editing work. With a hardware
encoder like the Snazzi* I and Snazzi*
III you will not require a high speed
pc to achieve the high quality of
video encoding. The encoding processes
are all done by the Hardware on the
card. A typical PII - 450MHz machine
will be able to do a good job. However
for Non-linear Editing the processor
speed of PC will determine how fast
it takes for the video to be rendered
(producing the final video file).
The more powerful your PC processor
speed, you shall be able to do rendering
and editing work at a much faster
rate. Our recommended processor speed
to achieve better result would be
PIII 650 MHz + or greater with 128
MB RAM + 4MB 3D Graphics Card or better.
Answer :
Firewire is a new digital
interface standard (IEEE-1394) that
allows super HI speed data to be transferred
up to 400 mbps (33 times your USB1.1
port). The purpose is to allow digital
video (DV) signal which runs at 25
mbps to be transferred directly into
your hard disk, edit it and output
the final DV video back to the Camcorder.
Since the entire transfer process
stays in digital format, you will
enjoy zero loss in quality and retaining
the quality of your finished video
to be identical to its original source.
