Audio Bit Rate:
Choose the audio bit rate you like here.
Audio bit rate is expressed in kilobits per second.
Frame Rate:
NTSC system uses 29.97 FPS (Frame Per
Second) while PAL system uses 25 FPS.
Variable Bit Rates:
Checking this box will use variable
bit rates to record. Usually, this will have better video
quality. However, CPU loading is higher as well.
Audio Frequencies:
Standard DVD audio frequencies
are 48 KHz while other formats use 44.1 KHz.
Lock current channel while recording:
Checking this
box will disable the channel switching. Unchecking this
box can change channel while recording.
Note
Switching channel while recording doesn’t mean you can
record two channels simultaneously. Instead, it is to
record another channel after the switch.
CODEC
CODECs encode to and decode from video files, usually
with a compression scheme, examples include, MPEG-4
and DiVX CODECs. In addition to the CODEC supplied
by Compro, ComproPVR can use third-party CODECs
that are already installed on your system. Select “Use
Customer Encoder” in other to use third-party CODECs.
Note
If you would like to record video in MPEG-4 format, you
must supply your own MPEG-4 CODEC. You can
download MPEG-4 CODEC from the following web sites.
