14 Motion Design B-Roll Ideas for Talking-Head and Explainer Videos
Fourteen motion design B-roll ideas for talking-head and explainer videos, from kinetic type and animated charts to chapter cards, and which line of your script each one fits.
A talking head holds attention for a while, then the eyes drift. B-roll is how you buy that attention back. The trouble is that most B-roll advice stops at "add stock footage", and stock footage is bad at the parts of an explainer that matter most: the number, the claim, the three steps, the comparison.
Motion design B-roll is built from the script itself. Below are fourteen shot ideas you can use over a presenter or a voiceover, with the kind of sentence each one is for. Read your script line by line and you will usually find a match for every cutaway.
Start with the script, not the footage
Before picking shots, mark three kinds of lines in your script:
- Lines with a number ("churn fell 18%", "three times faster").
- Lines with a structure: a list, a sequence, a before and after.
- Lines you want remembered: the thesis, the punchline, the call to action.
Those lines are where B-roll does real work. Everything else can stay on the speaker.
1. Kinetic type for the line that matters
Set the key phrase on screen word by word, timed to the voice. Keep it to five or six words, one or two fonts, and let one word change colour or scale on the beat. This is the single most reusable motion design shot: it works for hooks, theses and sign-offs, and it reads with the sound off.
2. The counter that lands on the number
When the speaker says a figure, show it counting up from zero and stopping exactly as the word is spoken. Add the unit and a short label underneath ("monthly users", "per clip"). A counter turns an abstract number into a moment, and it costs a few seconds of screen time.
3. A chart that builds with the sentence
Bars that grow one by one as each item is named, or a line that draws itself left to right while the narration walks through the years. The rule: the chart should reveal at the pace of the sentence, never all at once. If the viewer can read the whole chart before the speaker finishes, it is too early.
4. An illustrated story beat
Explainers often pause for an anecdote: "In 1854, a doctor in London noticed...". A chart cannot show that, and stock footage shows the wrong doctor. A simple drawn scene, with a character and a setting, carries the story and keeps the visual style consistent with the graphics around it. If a story section grows long enough to be its own video, it is worth looking at tools that turn a finished script into a narrated, animated video scene by scene, with the same characters throughout, and cutting from that.
5. Icon row for lists of three
"It is cheaper, faster and easier to change." Three icons appear left to right, each popping in on its word, each with a one-word label. Lists of three are everywhere in scripts, and this shot handles all of them with the same template.
6. Process diagram with moving arrows
For "first this, then that, then the result", draw boxes connected by arrows and animate a dot travelling along the path as each step is named. It makes a sequence feel like a system, which is usually what the speaker is trying to explain.
7. Before and after split
A vertical wipe across the frame: the old way on the left, the new way on the right. Works for workflows, designs, prices and habits. Keep labels short and let the wipe happen on the word "now" or "instead".
8. The establishing shot
Not every cutaway needs to be a graphic. When the script moves to a place or a mood ("by the time the night shift starts..."), a few seconds of real-looking footage sets the scene better than any icon. This is where generated footage is useful: ClipBee describes itself as an AI stock footage generator where you describe the shot and get a royalty-free clip back, which suits this kind of atmosphere shot. Use these sparingly; one or two per video is plenty.
9. Quote card
When you cite someone, put the quote on screen with the name and source underneath, and highlight the three words that matter. Animate the highlight, not the whole card. Quote cards add credibility and give the viewer something to read while the claim sinks in.
10. Map or route line
Locations, supply chains, a product shipping from A to B: a flat map with a line drawing itself between points beats a globe spinning in space. Label only the places the script names.
11. Product UI with callouts
For software or app explainers, show the actual screen, zoom to the part being discussed, and add a callout box with the feature name. Slow, smooth zooms read better than fast ones; the viewer needs time to find the cursor.
12. Chapter cards
A full-screen card with a number and a short title ("2. Why it breaks") marks a new section. In a long explainer, chapter cards act like signposts and give the speaker a natural place to cut.
13. Background loop behind the speaker
If the presenter is on a plain background, a slow, low-contrast motion loop behind them (soft shapes, a subtle grid, drifting gradients) makes the frame feel produced without pulling focus. Keep it dark and slow.
14. The logo or product reveal
End on the brand: the logo assembling from shapes, or the product name set in kinetic type. Pair it with the call to action from your script, word for word.
Which idea fits which line
| Line in your script | Shot to use |
|---|---|
| A number or percentage | Counter (2) or chart (3) |
| A list of three | Icon row (5) |
| "First, then, finally" | Process diagram (6) |
| "Instead" / "compared with" | Before and after split (7) |
| A story or anecdote | Illustrated story beat (4) |
| A place or a mood | Establishing shot (8) |
| A quote or a source | Quote card (9) |
| The thesis or the hook | Kinetic type (1) |
Cutting the vertical version
Most explainers now get a second life as Shorts, Reels and TikToks, and the same B-roll can do double duty there if you design for it. Keep text inside the centre of the frame so a 9:16 crop does not slice it, and make sure every graphic still reads on a phone screen. For short faceless explainers built from scratch rather than cut down, Faceless Reels' Doodle Explainer template turns questions and facts into hand-drawn doodle videos with narration, visuals, music and subtitles, which is a different but related look to the shots above.
A quick checklist before you export
- Every number in the script has a visual.
- No graphic appears before the line that introduces it.
- Text stays on screen long enough to read twice.
- One visual style across all fourteen shot types: same fonts, same colours, same easing.
- The speaker is back on screen for anything emotional or personal.
