Here’s A Quick Recap Of Where We’ve Been So Far:

By now, you’ve made a lot of progress:

• You’ve picked your channel style (talking head, faceless, or AI avatar)

• You’ve chosen your core tools (CapCut, HeyGen, etc.)

• You’ve brainstormed dozens of Shorts ideas

• You’ve written a few scripts you’re ready to record

• And you know you’ve got the tools to write an irresistible verbal hook that capture your viewers attention from the start

Now it’s time to start bring your videos to life.

To do that, we’re going to start creating the visual assets you’ll need in your video: background footage, extra video clips (called B-roll), images, and animations.

Because aside from just hitting record and talking into a camera, you need supporting footage to make your Shorts more dynamic and engaging—to keep your viewers attention throughout your Short.

What Is B-Roll?

B-roll is extra video or images that help tell your story.

Think of it like adding color to a black-and-white sketch. It’s how you paint emotion, emphasis, and clarity into the picture. The visuals reinforce what you’re already saying in your script.

If your viewer hears “Here's how I organize my day,” and sees a quick animation of a calendar getting filled in, that’s b-roll. If they hear you say “I hit a wall after writing 3 scripts in a row,” and see a photo of someone rubbing their eyes at a laptop, that’s b-roll.

And it doesn’t always have to be video.

B-roll can be:

• A photo

• A chart or infographic

• A looping animation

• A drawing

• Even subtle text or visuals that play behind your voice

If it helps the viewer see what you’re saying, it counts.

Why B-Roll Matters (Even In Short Videos)

In writing, you use bold text, bullet points, or formats like 1 / 3 / 1 to keep your reader engaged.

In video, you use visuals.

B-roll is how you hold attention. It breaks up the monotony of a talking head. It reinforces what you're saying. It hides jump cuts, smooths transitions, and—most importantly—it keeps people watching.

And you don’t need a lot.

Just 1 to 3 well-timed visuals can make a huge difference in how polished your video feels.

As a general rule, aim to show something new every 3 to 5 seconds—even if it’s subtle. That’s why almost every high-performing Short you see on TikTok, Instagram, or YouTube has captions, cutaways, or quick visuals baked in.

Now—how you use b-roll depends on the format of your Short:

• Talking Head: B-roll cuts away from your face so viewers aren’t staring at you the entire time. It adds variety and helps you visually explain what you're saying.

• Faceless: B-roll is the video. There’s no anchor visual, so your b-roll clips need to do 100% of the storytelling work.

• AI Avatar: You’ve got a “host” on screen, but the b-roll still plays the same role—it supports your voiceover and gives the viewer something fresh to look at every few seconds.

Next, I’ll show you how to actually use b-roll—and how to create it from scratch using AI tools like Sora.
