This video can be use for different purpose but the primary audiences are:

SANOU MSF information kit
Staff inductions in the field and HQ
Trainings
MSF external presentations (schools, conferences, events, etc.)
Face 2 Face, local antennas or groups of volunteers, motivation days, etc.

But the concept could also work for external channels such as your websites, youtube pages, facebook, etc. Just make sure that it is explained clearly in an introduction text, that the film was done primarily for MSF staff or future staff.
