What type of footage is primarily considered as supplemental or alternative?

C-roll is primarily considered as supplemental or alternative footage because it is used to enhance the storytelling aspect of a video production. B-roll provides additional context and visual interest, helping to illustrate points made in the main narrative, which is typically captured in the main shot footage. This type of footage allows editors to cut away from the primary subject, giving the audience a broader understanding of the topic and keeping the visual engagement high.

While main shot footage forms the backbone of the story, audio clips serve as sound elements rather than visual supplements. Text overlays can provide information or context but are not considered footage per se; they are graphical elements added to enhance the visual presentation. B-roll, therefore, stands out as the type that specifically serves as supplementary or alternative content, enriching the primary footage and contributing to a more polished final product.
