ABOUT SCHEDULES
A schedule is a list of one or more clip events to be processed in a recurring 24-hour period. Each
schedule also has information about Pipeline selection and settings, and optional publisher specifications.
Each schedule is displayed in a different window in Pipeline Control (Mac OS X) or a different tab
(Windows). Because Pipeline Control is a multi-document application, you can open, edit, and execute (in
Playout or Capture mode) several schedules at the same time. The number of media files you can capture
or play out simultaneously is based on the power of the CPU and disk write speed in your computer and
your network bandwidth (Network and Hard Disk Performance Requirements on page 29).
Creating Schedules. To create a schedule, select File > New Schedule. To save a schedule, select File >
Save or Save as, name the document and select a folder to save it in. When you save a schedule, it is
saved as a document. You can copy schedule documents in the Finder, move them to other folders, or
other computers. You can treat Pipeline Control’s schedule documents just like you do any other
document.
When you close a schedule window, if it isn’t named you’ll be asked to name it. If you’ve changed it, you’ll
be asked if you want to save changes
Each schedule contains several important groups of information: a selected Pipeline and its settings, plus
a list of one or more clip events arranged in a 24-hour timeline, along with their file names and optional
metadata, and optional publishers. Pipeline Control uses the schedule information you’ve configured, to
execute each clip event at the correct time, to either capture the clip, or play out the clip.
Schedules are Symmetrical. That is, if you capture a given schedule, Pipeline Control runs the schedule
and ingests encoded media from a specific Pipeline’s SDI port based on the clip events you’ve created in
the schedule, and saves it as a specific type of file, based on your settings. You can also play out the same
schedule, and the reverse events occur: each file you specify with a clip event is opened at the correct time
and the media is played out to the specified Pipeline for decoding and playout as SDI.
You can make as many schedules as you need to organize your workflows or tasks efficiently. You might
create schedules for each Pipeline you’re using, or you might create schedules for a specific set of clips
you need to capture or play out each day (or shift). Or, create schedules based on how you want the media
encoded, for use in an edit system, for example.
Note
Active schedules (schedules in Preview, Capture, or Playout mode) must first be
placed in Idle mode to close them. You may be interrupting a clip event, so check first.
