What is b-roll, and how does it differ from a-roll?

B-roll is supporting footage that adds context to your main shots. A-roll carries the core story, such as interviews, narration, or the demo itself. You use b-roll to establish place, cover cuts, and guide attention while the main audio continues. Think of b-roll as the visual helper that makes the lesson or message land.

When should I choose AI b-roll instead of stock footage or a live shoot?

Choose AI b-roll when you need specific, custom shots that stock libraries do not cover or when you want to move faster than a live shoot. You save time and budget whenever a quick generated clip beats a full production day. For high-stakes stories that require real people or real locations, schedule a live capture or use licensed stock. Many teams mix all three so every scene fits the goal and budget.

Which AI models can create b-roll, and how do they compare?

Modern text-to-video models can generate short b-roll clips from clear prompts. OpenAI's Sora family focuses on realistic motion and longer coherent shots, making it a strong choice for naturalistic scenes. Google's Veo models target high-quality video with creative control and, in their latest versions, support for richer audio. Capabilities change fast, so it is best to review the latest model pages in Visla and pick the option that matches your brand look, clip length, and budget.

What is b-roll?

B-roll is supporting footage that complements your main audio and A-roll (your main footage). You use it to show context, mask edits, or illustrate a point while the narration keeps flowing. Think hands on a keyboard, a city skyline, or a lab close-up: just simple shots that give context to your larger story.
