What is B-Roll?
B-roll is supplemental footage that adds visual interest and context to your main video content (A-roll).
In video production, "A-roll" is your primary footage—usually a person speaking to the camera or the main action. B-roll is everything else: cutaway shots, atmospheric footage, close-ups, and visual aids that make your video more engaging.
B-roll serves multiple purposes:
1. **Visual Variety**: Prevents viewer fatigue from watching one static shot
2. **Hide Cuts**: Covers jump cuts when you edit out mistakes or pauses
3. **Illustrate Points**: Shows what the speaker is describing
4. **Set the Mood**: Establishes atmosphere and context
For EdTech creators, B-roll might include:
- Screen recordings demonstrating software
- Stock footage related to the topic
- Animated graphics or diagrams
- Photos or images with Ken Burns effect
Examples
- A finance YouTuber shows stock charts while discussing market trends
- A cooking tutorial cuts to close-ups of ingredients being prepared
- An EdTech course shows animated diagrams while explaining concepts
