Genre identification through convention analysis

Comedy

This genre of film usually has light-hearted trailers so it can set the tone for a fun and humorous movie. Although other film genres may have elements of comedy like action and dramas these will rarely occur within the trailer as they aim to maintain it as serious and action-packed as possible.

One of the most common conventions that can be found within this genre is upbeat music editing. In many comedy trailers there is upbeat music to set a light hearted and humorous tone but this music can suddenly stop to emphasize a funny moment or line of dialogue. This is not only humorous but it helps set up characters, for example at 0:52 in the 'Daddy's home' trailer,https://www.youtube.com/watch?v=2sgpwTBnuLo  the upbeat music is suddenly cut to emphasize the humour and nature of the step-dad's character (will Ferrell) as he takes a clear insult as a compliment.

Another convention is the alternate use of a climax. Climaxes in actions or dramas are used to visually stun the viewers with great action packed, gripping shots. However in comedies, climaxes can be used to do just the opposite. fast paced editing and tense music is used in the exact same manner but is used to set up an intentional flop for comedic effect, an anti-climax.

For example in the trailer 'Spy' https://www.youtube.com/watch?v=mAqxH0IAPQI  at 1:44 a climax is built up with fast paced editing and increasing music/ FX only for the main protagonist to fall off her motorbike in slapstick fashion. This is done for comedic effect as the build up made it look as though the climax was going to be epic, like in an action film, when actually the main protagonist fails at the most clinical moment which is done intentionally to emphasize the character's, and indeed the whole film's, humorous nature.
