How to Add Auto B-roll and Emojis to Captions in Submagic

Beyond captions, Submagic can read your transcript and suggest B-roll clips and emojis tied to keywords, which keeps viewers watching. This guide shows how to add both without overdoing it.

• A Submagic project with captions generated and corrected
• A clear sense of which words to emphasize
• Restraint, since too many effects hurt retention

Step 1: Open the B-roll panel

In the editor click B-roll. Submagic scans your transcript and proposes stock clips matched to keywords it found, placing them at the right moments on the timeline.

Step 2: Accept, swap, or remove clips

Review each suggestion. Accept the ones that fit, swap weak matches for something better from the library, and remove any that feel random. Aim for a few well-placed cutaways rather than a wall of stock.

Step 3: Tune B-roll duration

Drag the edges of each B-roll clip on the timeline so it covers only the relevant phrase. Two to three seconds is usually plenty before cutting back to you.

Step 4: Add emojis to captions

Open the Emojis panel. Submagic suggests emojis above keywords, for example a fire emoji over a hot take. Toggle the ones you like; remove anything that looks forced.

Step 5: Preview and export

Play the whole clip to confirm B-roll and emojis land on the right beats and never cover the captions. Then export at 1080p.

Result: a flat talking-head clip gained three tasteful cutaways and a couple of emoji accents, lifting watch time without feeling cluttered.
