3 Video and Audio Stream Configuration

3.1 DV Stream

Figure 6: DV stream settings

DV Type: Use this setting to change your DV type. Note that PAL DV IEC chroma sampling is 420 while
other variants of DV have a 411 sampling.

Bit rate: DV IEC bit rate is always 25Mbps, while DV SMPTE bit rate can be 25, 50 or 100Mbps.

Video System can be PAL or NTSC (25 and 50 Mbps bit rates). DV SMPTE at 100Mbits/s (DVCProHD) can
be 720 progressive lines at 50 or 59.94 frames per second; 1080 progressive or interlaced lines at 50 or 59.94
frames per second.

Audio Embedded: Use this setting to define the status of the audio channels embedded in the DV stream. The
“Undefined” setting should be used when you want your plug-in to be able to process DV streams whether or
not they contain audio.

Nb Audio Channels: The number of audio channels embedded in the DV stream is usually constrained by
your DV type and bit rate. However, DV IEC allows 2 or 4 audio channels.

Audio Sampling Frequency: The audio sampling frequency can be set to 32, 44.1 or 48 kHz depending on
the DV type and number of audio channels.

Audio Quantization: The audio quantization is automatically configured to 12 or 16 bits depending on the
previous settings.
