Research and Planning: What Is An OTS?

I need to include awareness of the conventions of an OTS into my blog - demonstrate that I understand what are the conventions and how they then apply to short films

I followed this link to complete the task relating to Se7en

for the second task complete the tasks but using only short films - deconstruct and analyse/compare the OTS to three different films.
