B-Roll: When to Use It, When to Skip It (A Practical Guide)

B-roll is one of those things that everyone says you should use, but nobody explains when NOT to use it. I've seen shorts that are 90% B-roll, and they feel like a slideshow. I've also seen shorts with zero B-roll that feel engaging because the speaker is compelling.

So when should you actually use B-roll?

The Rule: B-Roll Should Illustrate, Not Decorate

Here's my simple rule: use B-roll when it adds information that the speaker isn't conveying through words alone.

Good B-roll usage:

Bad B-roll usage:

The 2-Second Rule for B-Roll

Each B-roll clip should last 1-3 seconds maximum. Any longer and the viewer starts wondering what they're supposed to be looking at.

I aim for 2-second B-roll clips. Long enough to register, short enough to keep the pace up.

Where to Place B-Roll

B-roll works best at transition points:

B-Roll Sourcing

Where do you get relevant B-roll without paying for stock footage?

ApexClip actually handles this automatically — it detects when B-roll would be helpful (based on semantic analysis of the transcript) and suggests relevant placement windows.

The Anti-Pattern: B-Roll Addiction

I've seen creators who can't stop adding B-roll. Every 2 seconds, there's a new clip. The result? The video feels disjointed. The viewer can't focus on what the speaker is saying because they're constantly processing new visuals.

Less is more. Use B-roll when it adds value. Skip it when the speaker is compelling enough on their own.
