Theatrical vs Teaser Comparison

This is my analysis on theatrical and teaser trailers. After watching multiple films' theatrical and teaser trailers, I discovered that the tension in a theatrical trailer has small peaks throughout to keep the audience on the edge of their seats, and then increases rapidly near the end to create excitement and a buzz for the film. However, the tension in a theatrical trailer then drops down at the end. Whereas in a teaser trailer, the tension usually builds up throughout the whole trailer and leaves the audience tense without a feeling of equilibrium.

Typical music in a theatrical trailer matches the rate of the tension and will get louder when the tension increases, apposed to a teaser trailer where a typical convention of music is that it increases with the tension, and then once there is a very tense or jumpy part, it will go silent, and then the music with be back at the end.

You can see above how the length of a theatrical trailer is considerably longer and has many more cuts. The dialogue in a teaser trailer is minimal, if at all, and the credits are likely to be fewer than in a theatrical trailer.
