FCPX Sharing full Library using Compressor

Thus technique definitely isn't for all! It's quite complex (though the video is a very clear step by step) AND requires the additional programme Compressor to work.

Ideally you can build and share a main Library first, then share additional clips as they come in, keeping file names and tags identical so that project files (the tiny XML files) can be shared via email. But this is an alternative if there's going to be gap in meeting up. The idea is to radically reduce (to 20%) the file size of the source video clips for easy online sharing. Once complete, a shared project file can be re-linked to the original full size media.
