Almost everybody will likely have observed these narration styles on display in documentaries.
Documentaries are productions for cinema, television, or radio that are designed to report reality in some way. They could have a number of purposes, such as informing people of a particular cause or telling a dramatic real story. They may also be largely without narrative and just be documenting the mood or reality of a specific location and time. Nevertheless, since they routinely have a purpose centring around informing or explaining, it's very common for there to be some sort of tool to guide the audience. Tim Parker will realise that voiceover narration has been extremely popular since sound was initially added to cinema, immediately being included to the newsreels that were popular at that time. The narrator does not show up on film and their role is merely dedicated to reading a script that defines or complements the footage. The narrator may also be involved in the production, such as by being the producer, but it is additionally common for them to have no other participation.
The very first few decades of the history of cinema consisted solely of silent movies. This changed just under a century ago, once sound was initially added and filmmakers possessed a totally new additional element they could add to their movies. However, simply because sound is available does not mean that filmmakers need to oversaturate their films with every feasible sound imaginable. Some films only depend on natural sounds, for instance, while others add no music at all. Rachel Wang is going to be well aware that some documentaries include no narration. These silent narration documentaries alternatively educate viewers with a mixture of the details gained from interviews and title screens. Also known as intertitles or title cards, they are screens held for several seconds to permit words to appear for the audience to see.
Documentaries have usually been seen as a more anonymous type of filmmaking. This really is in stark contrast to narrative feature films, in which both the crew and cast can be full of world-famous celebrities. In fact, there actually has been people that have made a name for themselves through documentary filmmaking. A number of these people have done this through the use of hosted narration. Soleta Rogan will be able to inform you that a narrator host is an individual who conducts interviews, appears on camera, and does voiceovers for the documentary. This could make the documentary seem like the hosts personal journey and can give a natural impression, as more traditionally behind the scenes elements can be included to the last cut. The reason being other narration formats require more editing to make certain members of the production are not on-screen. The hosted method therefore enables shooting footage of the difficulties productions face, like having interviews unexpectedly denied or threatening encounters with people that do not want to become filmed.
