Audio Frequency
You can select between the following:
• 48.0 KHz (MPEG-1 L2)
• 44.1 KHz (MPEG-1 L2)
Note: Select 48.0 KHz (MPEG-1 L2) if you want to capture MPEG-2 for DVD disc.
Audio Bit Rates
The audio format is always compressed in MPEG-1 Layer 2 audio. CapWiz also
automatically sets the audio sampling rate to 44.1 kHz for VCD and SVCD settings and
48 kHz for DVD video. We give you the choice to select the audio bit rate for your custom
video captures in the range from 192 kbps to 384 kbps.
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 the DVD authoring software will not directly
burn it, or your player will not play it back.
VCD, SVCD and DVD Legal Settings (check our web site for FAQ's and other updates to this list):
