Video Bit Rate:
You will notice that you have the ability to select a video capture rate of up to 15 Mb/sec. You will
also notice that any bit rate over 9 Mb/sec. is red in color. This is because any bit rate above 9
Mb/sec. is not supported by DVD players and DVD burners. We allow you to capture at higher
rates because some users may want to have the capability to capture at the highest rate possible
and don’t have DVD burning as a project goal. Just keep in mind that if you want to burn your
video onto a CD or DVD disk, don’t use a setting higher than 9 Mb/sec. or lower than 2 Mb/sec.
DivX Custom Settings:
Set Video format to DivX and you now can select the following capture resolutions:
DivX Profile
NTSC PAL
Portable 352 x 240 352 x 288
Home Theatre 640 x 480 640 x 576
Note: DivX video is highly compressed and takes more CPU Umph (power) than MPEG-1 or
MPEG-2 captures. Therefore we have set the minimum CPU spec as follows:
DivX Profile CPU Speed
Portable 1.8 GHz or faster
Home Theatre 2.4 GHz or faster
Since captures at lower CPU speeds will not be acceptable, CapWiz will not allow DivX captures
on slower machines.
DivX Audio
DivX is a video codec only. Our friends at DivX networks have set the standard for compatibility of
DivX files with DivX certified playback devices to use either MP3 audio or MPEG-1 Layer 2 (MP2)
audio. CapWiz supports hardware compression of MPEG-1 Layer 2 audio.
The audio sampling rate can be selected by the user as 44.1 kHz or 48 kHz and the audio bit rate
setting ranges from 192 kbps to 384 kbps. A higher bit rate will make the resulting file size larger.
Custom Settings Caveats
We have provided lots of flexibility in the manner in which you can capture video at various
resolutions and audio/ video bit rates. We have provided this flexibility because many customers
have asked for this kind of capability. However, think about your project goal before you begin
recording. If your intent is to capture video to be burned to CD or DVD disk, then capture at
resolutions and bit rates that are “Legal” for burning and playing back in players. If not, you may
find that you have spent hours capturing video only to find that it the DVD authoring software will
not directly burn it, or your player will not play it back.
