Create Proxy MPEG Rules
These rules create MPEG material from a Profile or M-Series movie. This is also
known as a “scavenge” operation and is the same as Sequential encoder functionality.
Depending on the desired behavior of the system you may have to create multiple
rules for the MPEG creation. There are four types of rules for MPEG creation, as
follows:
•
Exists when Rules Wizard starts up —
This rule will cause the Rules Wizard to
traverse a Profile/M-Series MDI to see if there are any Profile/M-Series files that
do not have MPEG asset associated with it. The Rules Wizard will only check the
system once after startup to see if it needs to create any of these assets.
•
Is recording
— This rule causes MPEG to be created while the system is encoding
the Profile/M-Series asset. This MPEG will only be created if you have an
Advanced Encoder configured in the system.
NOTE: The “is recording” rule should not be configured with the “is created
(closed)” rule referencing the same Profile/M-Series storage location. Also if any
other process is associating MPEG and the high-resolution material together this
rule should not be configured for that location.
If you want to reserve an Advanced encoder to only create MPEG for assets that
are created by the ingest you will need to have the MPEG material be created in a
separate folder than the other scavenge MPEG material and configure the advance
encoder's to only use this folder.
•
Is created (closed)
— This rule causes MPEG to be created after the Profile/
M-Series asset is done recording. It is most commonly used with Sequential
Encoders. Refer to
.
NOTE: The “is created (closed)” rule should not be configured with the “is
recording” rule referencing the same Profile/M-Series storage location.
•
Has its content modified
— This rule will cause the system to delete the proxy
material associated to a Profile/M-Series movie if the movie has its content
modified. It will then recreate the MPEG material for the asset. Note: This rule is
normal not configured unless the site’s workflow frequently modifies content in an
asset.
Systems will usually have either “Is recording” or “Is created (closed)” rule set up (not
both) for directories that are being monitored for the scavenge process.
