Video output connector compatibility
The following table shows which video output connectors are active depending on the
play channel video type setting. Use the table when making cable connections. To
change play channel video type, refer to
“Adjusting video output timing” on page 45 .
Guidelines for selecting video data rate
The type of video and how it will be used largely determines the video data rate setting
you should select. It is important to understand the type of material you will be
playing and select the appropriate setting. Generally set as high as possible to obtain
the storage capacity needed. Also consider the following:
• Sports footage (video containing lots of motion) requires significantly higher video
data rates than an interview show.
• Clips with lots of chrominance, typical of many commercials, require higher data
rates to maintain quality.
• Higher data rates should be used for any production work that requires multiple
generations or when the material is subject to up-conversion to HDTV.
NOTE: Information about iDDR system storage capacity for different video data
rates, see
“Product overview and key features” on page 21 .
