Capturing in DivX with Virtual
Dub
1.1
Getting started:
When
capturing in realtime DivX you will need some power in your PC system.
But I think
that my computer has more than enough power to mannage the capturing.
My computer
that I used in this guide:
AMD Athlon
1200Mhz
512MB RAM
GeFORCE 2
Pixleview
878 (TV IN)
Download
and install these software.
Those
softwares can be found at http://www.digital-digest.com
1.2
Settings
When you
have installed the softwares start your original TV software and choose the
channel you want to capture from.
Then start
VirtualDUB, go to “File” and choose Capture Mode. If you can see the TV
picture and here the sound, evreything is ok. Now we are going to choose the
DivX Codec. Go to “Video” and choose “Compression” and select “DivX ;-) MPEG-4
Low Motion”. Now press the configure button and choose the bitrate. (You can
use a DivX Bitrate Calulator to calculate the final file size. For ex. if you
want to put the movie on a CD later.)
I used 900
KiloBit/sec when I recorded a moive that was 86 minutes long and I got the
final size to 649 MB.
Now click
ok till you got back to the main window. Now go to “Video” and “Set custom
format”, now you can choose the resolution, my advice is to use 512x384 or
640x480 pixles since we want the best quality. Go back to main window and
choose “Capture” and “Settings” to setup the FPS. The FPS should be 25.0 (PAL)
and check so that “Capture audio” is marked (unless you want no sound).
When you
are back at the main window go to “Audio” and choose “Compression”.
When capturing
you must use the PCM format and for the best quality, use:
PCM,
44 100 Hz; 16Bits; Stereo. (We will compress the audio later in this
guide.)
1.3
Capture
Now the
setup is finnished and we are ready to capture. Go to “File” and choose
“Set
capture file”, enter where you want to save the movie and click ok.
Go to “Capture”
and choose “Capture Video” too start capturing.
When you
are capturing in DivX you should close all other programs to get the best
result.
To finnish
the capture press any button on your mouse and the capturing will stop.
2.1
Edit
Now you
should have an AVI file, locate the file and you will see that the file is
bigger than you thought, don’t worry nothing is wrong. The AVI file is big
because that we haven’t compressed the audio yet. Now open VirtualDUB and go
to “File” choose
”Open video file”, locate and open the captured file.
Now we are
going to compress the sound to make the file size smaller.
Go to
“Video” and select “Direc stream copy”, and now go to “Audio” to select
“Full
processing mode”. Select “Compression” under the “Audio” menu and choose
“Divx ;-)
Audio” now you can choose a lot of different bitrates. For normal quality
select “128 kbps, 44KHz, 16kb/s”.
Now go to
“File” and “Save as avi”.
2.2
Finnished
Now
everything is done and you should have a playable avi file.
If your
movie is lagging try to capture at lower resolution but that will decrase the
quality.
Yoy should
always make a test to see if it works before you start capturing.
If you not
are using PAL and want to capture anyway, I strongly recomend that you read
