Frame Chase Capture
237
Conventional Capture
A conventional capture creates media files (one for each track) in a temporary location ( Avid
MediaFiles\MXF\1\Creating
on a media storage volume). These media files are not available
for check-in to Interplay while the capture is in progress, and you cannot view or edit the files.
When the capture ends, the files are moved to their final location (
Avid MediaFiles\MXF\1 ).
Only then are the files checked in to Interplay and made available for use.
Frame Chase Capture
A Frame Chase capture creates media files directly in Avid MediaFiles\MXF\1 and creates a
special type of clip known as an in-progress clip. In-progress clips are represented by In-progress
master clip and In-progress audio clip icons.

An initial check-in to Interplay takes place 10 seconds after the capture begins. Subsequent
updates to Interplay occur at intervals that you define in the Capture Settings dialog box.
As soon as the initial check-in takes place, the in-progress clip is available for viewing and
editing on any applications in the workgroup. Portions of the clip’s media that have already been
captured are visible in monitors, while portions of the clip that have not yet been captured are
represented in monitors by a “Capture in Progress” slide.
Metadata associated with the clip (including information such as comments and markers added
during capture) updates at the defined intervals. For example, you might be capturing an
in-progress clip with the update interval set to 1 minute. A comment you enter 5 minutes and
20 seconds after capture begins is associated with the clip in Interplay (and therefore available to
any applications in the workgroup) in the update that occurs 6 minutes after capture begins.
Your Avid editing application and Interplay might not know the true length of a capture in
advance (because you can end a capture at any time). So the length of an in-progress clip is based
on the expected duration of the clip when capture begins. This duration is either the duration
indicated by IN and OUT points set in the Capture tool, or, if no marks are set, is a default
duration that you define in the Capture Settings dialog box.
When the capture ends, a final update to Interplay occurs. This update changes the clip’s type
from an in-progress clip to a conventional master clip, and if necessary changes the clip’s
duration to the actual length of the capture.
You can also refresh AMA in progress clips when performing an edit while capture. From the
Bin menu, select Refresh In-progress AMA Clips.
