Software Overview
You can set the length of the chunk, so that media is available shortly after capturing has
started. At each chunk interval, more media is available, adding to your previous media. The
AirSpeed supports chunking by creating clips of the material at a predetermined duration
times and by periodically checking in captured material through the Avid Unity
MediaManager client interface.
AirSpeed captures short chunks of media up to a transition time, then from the transition
time forward, media is captured at your selected Chunking Period. For example, if the
Chunking Period is set to 3 minutes, the Transition Interval to 1 minute and the Short
Chunking period to 15 seconds, media checks in at 15, 30, 45, 60, 240, 420 seconds, etc. See
the following illustration.

In the AirSpeed workflow, even though MXF media is streaming to Avid Unity, metadata
becomes available according to the Channel tab chunking settings. MXF media follows the
same chunking model as the OMF media. To have access to the captured MXF media as
soon as possible, set your Short Chunking Period to the minimum value of 15 seconds and
both the Transitional Interval and Chunking Period to 3 minutes.
Chunking values are set in the Setup > Channel tab of the AirSpeed UI. For chunking time
constraints, see “Channels Tab” on page 85.
RetroLoop
RetroLoop™ provides the ability to capture material for a predetermined, user-selectable
amount of time before an unknown event occurs. RetroLoop captures media continuously in
a loop, using a predetermined amount of storage space. Start capturing media using the
RetroLoop feature; when the event happens, start a normal capture and capture as much of
the event as you want. The end result is a clip that contains material before and after the
event.
For information about entering RetroLoop mode, see “RetroLoop Mode” on page 112.

You must initiate RetroLoop using the AirSpeed front panel.
