Description
In bug 668028 we implemented the ability for pitivi to export project files and associated media as a tarball.
Ideally, GES should allow that in its formaters and allow importing directly from a tarball (no need for the user to manually extract from the tarball, to load the project and to run the missing clips URI search thing).
