There are several reasons why a couple may not be able to choose the music for their wedding film. One of the main reasons is copyright laws. In order to use a particular song in a wedding film, the filmmaker must have the legal rights to that song. This typically involves obtaining a license from the song's copyright owner, which can be a complex and time-consuming process. If the couple chooses a song that the filmmaker does not have the rights to use, it may not be possible to include that song in the film.
Another reason why a couple may not be able to choose their own music for their wedding film is that the film may not be able to be shared on social media. Many social media platforms have strict rules about the use of copyrighted music in videos, and they may not allow videos with unlicensed music to be shared on their platforms. This can limit the couple's ability to share their wedding film with their friends and family on social media.
Finally, even if the couple is able to choose the music for their wedding film and the film can be shared on social media, the filmmaker may have their own artistic vision and may want to use a different soundtrack to enhance the overall look and feel of the film. In this case, the couple may have to compromise and allow the filmmaker to make the final decision on the music.
