Configuring the video codec type
On the Profile XP media platforms equipped with one or more Video Processor boards,
you can configure each of the codecs to be one of five types. The type principally applies
to the video compression used when recording. Any of these codecs can play all standard
definition clips of any of these supported format seamlessly, back to back, without any
configuration changes.
• DVCPRO 25 Codec — This type uses the DVCPRO compression format at
25Mbps. To configure a channel as DVCPRO 25, you must have at least one codec
configured as this type.
• DVCPRO 50 Codec — This type uses the DVCPRO compression format at
50Mbps. This codec type is available as a selection only if you have the license for
50Mbps operation. To configure a channel as DVCPRO 50, you must have at least
one codec configured as this type.
• MPEG Encoder — This type configures the codec to be an MPEG encoder for use
with MPEG recorder and MPEG D10 recorder channel types. It is important to
remember that these encoders have different capabilities than the encoders on the
Profile XP MPEG Encoder board. Video is encoded only at bit rates up to 25Mbps
or with the license, up to 50Mbps.
• MPEG Decoder — This type configures the codec to be an MPEG decoder for use
in playing out standard definition MPEG video.
• MPEG Codec — This type configures the codec to be an MPEG codec, able to
switch from Play to Record without using a second codec resource. The MPEG
codec supports video at bit rates up to 25Mbps, or with the license, up to 50Mbps,
including MPEG D10. Choose this configuration for use with MPEG Player/
Recorder or MPEG D10 Player/Recorder channels
NOTE: When you select or change a video codec type, you must restart the media
platform for the change to take effect.
To configure a video codec:
1. Choose Video Codec in the Configuration Manager window. The Video Codec
dialog box appears. The DVCPRO 50 codec type will not appear if you do not have
the 50Mbps license.
