General Guidelines on Using FTP with AirSpeed 5000
174
To achieve and promote optimal stability and performance in your workflow, consider the
following:
- As discussed previously, to increase your “realtime” system performance, limit your
simultaneous FTP transfers to and from the system to no more than four (4).
- If you want to play clips while they are transferring via FTP to the server, try to avoid
performing Transfer Engine transfers at the same time as FTP transfers.
- Performing large deletes may slow the response of the system to inventory requests and
transfer activity. Instead, we recommend that you perform smaller deletions
periodically, or schedule larger deletions during times of lower activity.
- If you are experiencing slow system performance when performing multiple transfers,
try setting the Read/Write buffer size on your FTP client to a larger buffer size. We
recommend 256k. Other values will operate, but might not provide the best experience.
- If you are experiencing performance issues, check to see if your FTP client supports
throttling. If so, we recommend that you adjust the throttle settings in your FTP client to
allow for sustained bandwidth throughout the length of the transfer.
• The use of “Anonymous FTP” is not supported.
• FTP operates over Port 21. By default, this port is not blocked by a firewall. However,
depending on your client configuration, it might be necessary to open this port.
• The AirSpeed 5000 FTP server does not support Avid Media Browser.
• Once you have connected to your server, the media files available on the server can be found
in the directory /active/clips.
• File sizes, as viewed on the server from your FTP client might not match the file size of the
transferred MXF OP1A file. This could be because of the following reasons:
- The file size on the server is based on the format of the file on the server. That file is not
an MXF OP1A file. Therefore, transferring it via FTP creates a new MXF OP1A files
that is different from the source.
- If someone has set Mark IN and Mark OUT points, the clip will be different in size.
Only the media between the Mark IN and Mark OUT point will be transferred. To verify
the correct Mark INs and Mark OUTs for the clip, launch the AirSpeed 5000 Remote
Console application, open the Inventory pane, and review the clip from there.
• Due to compatibility issues across different products, you should avoid using these
characters: * | \ : “ . < > ? / % # [ - . For examples, see the following:
- In many cases, we will prevent these characters from being entered. For example, if you
type any of these characters * | \ : “ . < > ? /, transfers will fail.
- If you type a percent (%), it will be converted to an underscore (_) in the Clip Name,
and/or Video ID fields.
