B-Roll

B-roll refers to supplementary footage that is intercut with the main footage, called A-roll, to add visual interest, context, and professional polish to video productions. While A-roll typically features the primary subject such as an interview or main action, B-roll provides cutaway shots like establishing shots of locations, detail shots of hands working, reaction shots, or relevant imagery that illustrates what the speaker is discussing. B-roll also conveniently covers edit points and jump cuts.

Three-Point Lighting

Three-point lighting is the fundamental lighting setup used in video, film, and photography consisting of three light sources positioned strategically around the subject. The key light is the primary and brightest light, placed to one side creating the main illumination and shadows. The fill light, placed opposite the key, softens shadows without eliminating them. The back light or rim light, positioned behind the subject, separates them from the background by creating an edge highlight on hair and shoulders.
