Transferring a Clip Segment
007-4403-003 73
Note: If the clip cache resides on a striped XLV volume, the major alignment matches the
stripe size of the XLV volume.
Notifying the SGI Media Server
The SGI Media Server detects the clips when the clip is first loaded and every time the
SGI Media Server starts. The clips are then listed in mcclips.
If you place a clip in the clip filesystem, the first time you attempt to access the clip
through the SGI Media Server, it attempts to auto-detect the clip’s format and add it to
the clip list. However, until you attempt to access the clip, it will not be visible in a list of
clips you obtain from the Clip Manager. To see the clip immediately, use the following
command:
# vtrclip add clip-name
Note: There might be a delay because adding clips always has a lower priority than
playout or record.
You can also use the following MVCP command to notify the SGI Media Server of an
added clip:
# CADD clip-name
Transferring a Clip Segment
The vtrftpd utility honors in and out points on DIF clips for transfers from the real-time
filesystem on the server. You can transfer the segment of a clip between in and out points
instead of having to transfer the whole clip, saving transfer time and disk space in many
cases.
If a clip has no in or out point set, vtrftpd uses the following defaults:
• If the start point (beginning of the file) is invalid or missing, it is set to 00:00:00.00.
• If the in point is invalid or missing, it is set to the start point.
• If the out point is invalid or missing, it is set to the end of the file.
