If the file is under 20 GB, you can use the http://myairbridge.com site to send it. You can also send it to us via a service like Dropbox or Google Drive (if you have an account with one of those services that gives you enough space), and then send us a link. If you send via Dropbox, please zip any QuickTime files first, as Dropbox will sometimes change their resolution data.
We've found these options work well for most situations, but if you'd prefer, we can also set up an account on our FTP server so you can upload directly to us. Let us know if you'd like that set up.
