The following sections explain rules.
About configuring rules
The Rules Automation Settings page dynamically offers the appropriate options
based on the currently selected source, as follows:
Rules when the source is high-res material
These rules create MPEG, thumbnails, storyboards, and Real Media proxy from
high-res material. This is also known as a “scavenge” operation and is similar to
Sequential encoder functionality. Depending on the desired behavior of the system
you may have to create multiple rules for the MPEG creation. There are two types of
rules, as follows:
• Create while Recording — This rule causes MPEG to be created while the system
is still encoding the high-res material.
• Recreate Proxy if Content is Modified — This rule will cause the system to delete the
proxy associated with high-res material if the material has its content modified. It
will then recreate the MPEG proxy for the material. Note: This rule is normally not
configured for Open SAN systems. It should be configured for K2 storage systems.
The following takes place by default with both these types of rules:
• When the Rules Wizard starts up, it traverses a high-res device MDI to see if there
is any material that does not have MPEG proxy associated with it, according to the
currently configured rules. The Rules Wizard will only check the system once after
startup to see if it needs to create any of this proxy.
Rules when the source is MPEG proxy
These rules create thumbnails, storyboards, and Real Media video from MPEG proxy.
This is similar to Image Support Server (ISS) functionality. Most systems only create
thumbnail and storyboard material.
Tips for configuring rules
• Configure one rule per folder or “location”. Multiple overlapping rules that access
the same folder can produce looping behaviors and other unexpected results.
• If using SmartBin Encoders or Single-channel Encoders for ingest, don’t use
Advanced Encoder rules for ingest.
