Hey
whats up? When i was first going to type this up i was thinking
it was going to be very long and detailed, i then realized upon
typing it out, it is really very simple and only a few steps
are required.
For quite a longtime now i have been using a Dazzle (dazzle
usb) to capture and create my video cds. The main problem most
people who are new to video cd making, and/or the Dazzle unit
is how to make your vcds look good using a Dazzle. The problem
is that majority of people are using the Dazzle's "video
cd template" to make their vcds and if you do use this,
your result will look horriffic.So to help you out below i will
list some steps (and other stuff) you should use in order to
get the most and best picture from your Dazzle device. This
is mainly for mpeg 1, however mpeg 2 can still follow the same
procedures. However i should let you know now that doing my
method it can be VERY timely. It is always an issue of quality
vs time. If you want quality you have to sacrifice a lot of
time. I also wanted you to know that i did not list fine details
in this for encoding. As everyone does things a little different
and i want to keep this short and very basic so everyone can
use the info.

How
to make a good looking VCD using a Dazzle Capture Card
STEP 1:
The method i use.
First and foremost, i highly recommend using a small portable
fan and have it blowing on the Dazzle. This keeps the device
cool and helps stop frame dropping and/or possible audio and
video off sync.
Next we are going to change some settings in the Dazzle software.
Change the template to "movie quality" and change
the bitrate to 2900 (or however many zeros follow) also making
sure "high" is also checked. By doing this you are
increasing the data rate(bitrate) at which the Dazzle will capture.
If you have a slower pc, i would also check the "post process".
What that does is after you record your clip it will put the
audio and video together. Doing it that way takes a lot of stress
off your pc and is mainly for those with a slower machine, this
way you can capture long clips with no problems. If you can
uncheck the "monitor while recording" this also helps
the pc make a better capture. Once this is all done watch your
captured clip and you will see a big difference then when you
captured using the video cd template. I also never have the
sharpeness set higher then "1" doing so will add extra
noise and other artifacts to your clip. Trust me, "1"
is high enough.
STEP 2:
Here is where the time factor will come in. In order to make
your clip at vcd rate (ntsc bitrate for a video cd is 1150,
I beleive Pal format is 1120, but i could be wrong about that)
or Xvcd, etc, you now need to take your captured clip and run
it into a program known as an "encoder". Encoders
are programs that convert one format to another. Using an encoder
( i highly recommend using the TMPG encoder, it is very good
and info as well as links for it can be found on the site you
are on now), you would input your clip, play with the settings
in the encoder(another story and issue all together, not it
is not hard to do) and encode. THIS IS WHERE the time will come
to play, your clip can take anyhwere from 2-16hrs depending
on how long it is, the speed of your PC and if any filters or
such are used. For most of my clips i use filters (this gets
rid of virtually any and all noise from your clip). the TMPG
encoder's filtering system is the best i have ever come across.
Encoding time for me is on average about 8hrs for a 30min clip,(running
550mhz intel pent 3) but the result is very worth it.
STEP
3:
Once your encoded clip is done, you need a cd burning program
that burns video cds. adaptec, Nero, NTI, winon cd, video
pack 4, etc are just a few that allow this. For you nonstandard
bitrate users (making a vcd with a higherbitrate then normal),
NTI and nero, and video pack 4 allows this. Now take your
burned clip and watch it onyour PC, dvd player or where ever
you plan on playing it--enjoy. that is all their is to it.

How
to make an XVCD using a Dazzle Capture Card
Lets say
you want to make an XVCD (bitrate 2500) but you do not want
to encode it. YOU CANNOT simply capture at that rate with the
dazzle and burn it (unless it is only going to be played on
a pc). If you do, and you want to play it on a homedeck dvd
player, the audio will skip horribly. the reason is that Dazzle
does not give it the proper audio buffer rate for a higher clip.
to fix this, here is what you do: Using the tmpg encoder input
your clip. Now on the right change the setting to "system
audio only" (it has to be system and not just audio), and
using your backspace key erase the info that is shown on the
"video input" line for the Tmpg, this way only the
audio part of your clip can be seen. Encode the audio clip.
Tmpg encodes sound very quickly. Once this is done you take
your sound clip and using the tmpg tools section, remux (remuxing
is taking the video from one clip and the audio from another
and putting the two together) the new sound with your picture
(make sure the vcd nonstandard template is selected). Now you
have your 2500 clip all set. Burn it have fun
In closing,
using the methods described above you can make very good looking
video cds with the Dazzle. I too do not like the time it takes
to encode clips, but it is either that or having very bad/not
so good results using Dazzle's vcd template.

Filters
and TMPGEnc
OK, I have recieved a lot of email asking about this, so although
i will try to keep this as brief and to the point as possible,
in the end it will still be up to you as to what to set the
filters to and what works best for you.
The main filter i use in Tmpg is the noise filter, as this
can virtually wipe out any video noise you may encounter,
making your clip look that much better. Although be warned
using the filter on too high a setting can cause your picture
to get blurry and may add noise to the picture instead.
Here is the settings i generally use, as i have done quite
a bit of testing clips over and over with filters. My main
PC was destroyed so i have not made anything in a while. The
last version of Tmpg i had, had the noise filter broken into
3 small sections (still, range, and time axis). I am assuming
they are still going by these names, if not then the "still"
was the top setting, "range" was the middle setting,
and "time-axis" was the bottom setting. Whatever
number i made the "still" setting, i kept the "time
axis" setting the same, with the range being the variable.
Also their is a "high quality" box just under the
3 settings-- make sure you check this off to give it that
extra boost for your picture. AND make sure the "enable
filter" box is checked as well
OK, Breaking this down a little more--
1: if your clip is extremely good quality(aka dvd rip or somewhere
in that area--NO filters are needed
2: if your clip looks pretty good-very good, i would set the
filters to the following: STILL-between 1-8, RANGE-1, TIME
AXIS-between 1-8
3: if your clip looks half way good-decent, i would set the
filters to the following: STILL- between 1-8, RANGE-2, TIME
AXIS- 1-8
4: if your clip looks ok-poor: STILL 1-4, RANGE-3, TIME AXIS
-1-4
5: if your clip looks fair-below: STILL 1-3, RANGE 3-4, TIME
AXIS -1-3
Again
that is pretty much how i set the filters in a nutshell. What
i noticed happens when you make the filters too high(lets
say for still/time and making them 20 or higher) It caused
more noise in my picture and it can "soften" the
pic too much that it will make it look worse. Also in darker
lit scenes when the filter is sometimes too high it will show
up highly in the background and this is something you do not
want. The RANGE pretty much is the main setting. If you set
that high, you will not need to use a high number for the
other filters as the "range" will now cover more
of the area using a stronger filter.
THE
TMPGENC MACRO BRICK NOISE SETTING(aka soften block noise setting)
This setting on the TMPG(and it is found under the "quantize
matrix" tab of tmpg) will and can reduce the "block
noise" commonly associated with video cds(mainly at normal
rate, but not all the time).
Again i have found with a lot of testing that if you have
this feature on, i keep the intra and non intra blocks the
same number. Older versions of TMPG kept the setting at 35
for both. This is a good rate to use, actually 35-40 was ok.
Going higher (at least from what i found) resulted in extra
block noise that i did not want.
ALSO while under the "quantize matrix" tab, click
on the "floating point dct" box, this will help
produce a better picture for you.
FOR HIGRATES/XVCDS/SVCDS - i never really use the soften macro
noise filter, as the bitrate is high enough to compensate
for any brick noise that would have been made using the normal
rate vcd setting.
ALSO i did not use this filter for anything with the quality
of a dvd rip.
TMPCENC
AND ANIMATED FEATURES
This is pretty interesting, for this section take everything
i have mentioned above and throw it out of the window!!! For
some odd reason on more bland drawn cartoons with not many
details(ex GI.JOE, The Simpsons,
the older Transformers cartoons, etc) if you come close to
blasting each of the noise filters, it actually made the picture
look 100 times better then what i ran in!!! I could not believe
it. I would set the STILL and TIME settings anywhere from
80-100, and the range 3-4. Macro blocknoise close to 100(but
its still ok to leave this at 35, as i found out later the
close to 100 setting isnt needed for it). My clips became
very vibrant and rich in color, some minor detail was lost,
but it made the picture look as if i just taped it from a
high source and not taken from 14-16 year old Beta/ex rental
tape--to put it simply, it looked better then the original!!!
Again blasting the filters like this only seems to benefit
older cartoons.
ANIMATED features with a lot of detail (ex Akira, ghost in
the shell, heavy metal,etc) i would follow the settings i
mentioned above that i use for movies, as blasting the filters
with these types of animated cartoons will cause it to look
like havoc.
Have fun!!! Hope this helps some of you out, remember despite
it being a hassle, constant testing will let you know what
settings are right for you. thanks again!!
