What is the ruling on watching educational video films on massage that do not involve the baring of 'awrah (private parts)?

Video and photographic imaging are subjects of contemporary scholarly disagreement, with the preponderant opinion being their permissibility so long as they are not associated with something forbidden. If the films do not expose 'awrat (private parts) and do not cause fitnah (temptation/strife), then there is no harm in watching them for learning and benefit.
