Multiple Simultaneous FTP Operations
FTP client programs that allow multiple simultaneous data transfers should be set to allow only
one data connection at a time.
While it is possible to log in from multiple clients, it is only acceptable to perform multiple file
transfers when the system is idle or playing or recording on a single channel.
File Sizes Reported in FTP Listing
The size of a clip reported in the file listing depends on the file type you are going to download
from the server. In any case it is a close approximation of the amount of data that will be
required to store the downloaded file. See the discussion of the .mxf and .vfc file types.
Overwriting Files
It is the responsibility of the client application (Windows Explorer, FlashFXP, etc) to ask the user
if they want to overwrite a file.
Note that some types of files (such as .mov and Targa) change their file extensions when they
have been transferred into the server. In these cases, the FTP client cannot warn of a file
overwrite. It is important to take extra care when using these types of files not to overwrite
necessary files.
Interrupted and Resumed Transfers
If a transfer is interrupted (for example, by a dropped connection) the transfer must be restarted.
Resumption of a partial transfer is not possible.
Transfer of Edited Segments
The server sets MARK-IN and MARK-OUT points in a clip as “edit pointers.” For all edit
operations within a given server, these pointers produce “virtual edits” that save disk space, and
the time it would take to re-write the marked region as a new file.
When transferring clips via FTP, depending on the method used, either the material between
the edit points or the entire clip is transferred.
