About QuickTime import delay
When you copy a file into a K2 HotBin, the HotBin watches for the file to close and
the copy operation to stop, which should indicate the file is complete, before it begins
to import the file into K2 storage. However, Final Cut Pro repeatedly opens and closes
any QuickTime file as it exports the file, so it is possible that the K2 HotBin can detect
a file closed event and begin to import the file before Final Cut Pro is done. If this
occurs, the K2 HotBin import for that file fails.
To avoid this problem, when you configure a K2 HotBin you can configure the
QuickTime import delay setting. This setting allows you to adjust how long a
QuickTime file must be idle (no data being written to the file) before the HotBin
begins to import the file into K2 storage. The recommended default value is 15
seconds. If you have problems with failed imports and you suspect that Final Cut Pro
is holding on to the file with pauses longer than 15 seconds, you should increase the
QuickTime import delay time and re-try the import. The HotBin process constrains
the QuickTime import delay range to between 10 and 60 seconds.
Using Final Cut Pro on a K2 storage
Read the following topics to use access and edit K2 media with Final Cut Pro.
Operation guidelines
Take the following into consideration as you use Final Cut Pro on K2 storage.
• Do not use the K2 AppCenter "Erase Unused Media" operation on clips that you
are accessing on K2 storage.
Media access
1. From the Macintosh system on which you are running Final Cut Pro, access K2
media as follows:
• If your access method is file transfer via Flip4Mac (FTP), in Final Cut Pro click
File | Import | Grass Valley... .
• If your access method is file transfer via direct file copy, open the Macintosh
Finder.
• If your access method is edit-in-place, in Final Cut Pro click File | Open .
2. Browse to the location of the media in your K2 bin structure.
The QuickTime reference path/file is named according to the convention \name>\\.mov.
If accessing media on a K2 version 7.x system, all the files associated with the clip
are in the \\ directory.
3. Do one of the following:
• If your access method is file transfer via Flip4Mac (FTP), transfer the
QuickTime reference file to the local Macintosh system, then open the file in
Final Cut Pro and Save As to the location of your work in progress.
