
Video Source
is for those systems that support more than one type of input connector, this option specifies
which video connectors to capture from.

Composite - RCA type connector, usually colored yellow.

S-Video - standard S-Video source.

RGB - component RGB source.

YUV - component YUV source.

SDI - digital SDI source.

Audio Input
is used by those systems which support more than one audio connector.

Line In - this input is the unbalanced line level source. This connector is typically a 1/8" diameter phone plug
connecter.

Balanced - this input is balanced source. This connector is typically an XLR type connector. In fact, for
stereo audio, there should be two XLR connectors.

AES - digital AES source

Embedded AES - digital AES audio embedded with the SDI video signal. In this case, both the audio and
video will be coming in on the SDI video connector.

Video Aspect Ratio
for capture cards that support it is used to specify the aspect ratio of the video source.

Bitrate
- the MPEG-2 video encoder can be configured to use a constant bit rate encoder or a more advanced
variable bit rate encoder. The variable bit rate encoder will typically produce better results than the constant bit
rate encoder but the file sizes may be slightly less deterministic.

Audio Algorithm
- specifies the encoder to be used on the audio stream. This option may be set to be set
to MPEG audio but in virtually all cases, will be set to AC3. The default DVD bitrate for stereo (two-channel)
Dolby Digital is 192 kbits/sec. The bitrate can be set as high as 640 kbits/sec.

Bitrate Computation

Auto - this option will usually be used which will automatically compute the optimal bitrate for the DVD length
selected. The maximum value that will be used for the target bitrate is 8000 kbps. If a higher bitrate is
desired, the manual bitrate computation method should be chosen.
