YouSendIt‘s Final Cut Pro plug-in is a useful editor to editor collaboration tool. Right-click on a clip or a sequence in the FCP project, and choose Export > Send by YouSendIt. YouSendIt’s plug-in gathers the necessary source files in a queue, offering the option of including the project file as well.
Files are not compressed, and playing a sequence requires that the receiver must have FCP and all necessary codecs installed. It’s not much of a review and approval or general collaboration tool, but it might be useful for moving small projects via email without having to worry about attachment size limits.
YouSendIt has taken a first step towards making NLE collaboration over the web viable for small shops, but it’s not there yet. This is a huge growth opportunity, but also an opportunity missed. A Squeeze, ProCoder, or Compressor plug-in would be more useful to small shops.
