You can set the start, in, and out points of a clip using the command site editpoints.
By default, these attributes are not transferred with the clip.
Proxy Transfers
As mentioned previously, a get command with the FTP client on a server will do the
wrong thing by writing the file to the data partition of your real-time filesystem. Avoid
this use of ftp with vtrftpd. Instead, use proxy transfers between servers, as described
in the following paragraphs.
FTP allows an FTP client to control the daemon on two servers. The FTP client can be on
either of the servers or on a third server. Typically, the FTP client connects both servers
with a control connection, instructs one of the daemons (vtrftpd) to open a data
connection with the other, and then initiates the transfer between the two servers. The
two vtrftpd processes then correctly read and write the real-time files while
performing GRIO reservations.
The simplest way to achieve proxy FTP transfers is to use the vtrftp command, a Perl
FTP client that performs passive FTP transfers between servers. The vtrftp command
copies the start, in, and out points. Enter the following command sequence to use proxy
FTP with the UNIX ftp client:
server1 4# ftp server2
