Videography can take on many shapes, including digital animation, slideshows, and imaging technology to incorporate into the final product. For example, explainers are often employed to explain large concepts like complex projects or corporate organizations. Related to this are tutorials, which use videography to describe how to use products or services more narrowly. Interviews are effective communications tools to transmit first-hand information to audiences. Vlogs are the video equivalent of blogs and are incredibly popular modes of expression, often employed in social media to promote products and services. Live video streaming is hugely important for running professional corporate meetings and broadcasting events such as concerts. Aside from traditional camera videography, tools such as drone videos and 360-degree footage are becoming more popular.
