Patters seen within trailers

Hi! On Friday I decided to look at a lot of trailers that really resonate in captivating the audience. So what I did was write specific points that I felt would be useful to include within my trailer that can aid in capturing my target audience.

1. First conversation introduces characters. The conversation is usually short but gives a true insight towards the motive of the protagonist. It is usually his or her voice accompanied with other pictures to establish the setting of the story better.
2. Usually includes one entire scene of the movie, which is normally the twist given to the movie. For instance, in The Hunger Games, they include almost the entire scene of the reaping when they choose Katniss's sister. Using this method allows the audience to fully capture what is happening to not have any doubts.
3. The conversation that follows usually includes the purpose of twist. Maybe an opinion from one of the characters towards what is happening.
4. The rest are mostly pieces of what is to come but it leads the audience with doubt and wonder.
5. Includes conversation of what characters believe in and their values. To give them each a sense of identity.
6. Usually other trailers of the same movie use the exact same scenes. The only difference is their tonality and voiceovers are different. They use different music and different timing where they might include a conversation or two that was not seen in the previous trailer.
7. Another take on trailers like in Jackie is just using a voiceover and its accompanies with dramatic music and different scenes.
8. Some scenes that are difficult to shoot can be represented with a black screen and the noise. For instance, a gunshot and a scream to represent a shooting.
