Comparing Teaser And Theatrical Introduction

I already looked at Posters and Magazine front covers and analysed the conventions of them, now I will be analysing two existing films with teaser trailers and conventional theatrical trailers.The two films that I chose for this task is Transformers 'Age Of Distinction' and 'Minions'.I am going to to compare them and find the similarities and differences between them and in the end of this task it will show me what I need to put in my own teaser trailer to make it look real.
