Adding captions isn’t just about accessibility. It’s one of the highest-impact things you can do for engagement. Most social video plays with the sound off. Captions keep viewers watching. This guide covers everything from generating accurate captions to styling them so they stop the scroll.

​
Step 1: Generate captions

1

Import or record your video

Tap + on the Captions home screen and import a video, or record one using the built-in camera.
2

Choose your language

Select the language being spoken in your video. If multiple languages are spoken, choose Multiple Languages.
Choosing the right language dramatically improves transcription accuracy. Don’t default to English if your video is in another language.
3

Choose translation (optional)

If you want captions in a different language than what’s spoken, select the target language here. Captions will transcribe and translate in one step.→ See Dubbing & Translation for the full translation workflow.

Generate

Tap Generate captions. The AI transcribes your audio in seconds. Review the output in the timeline.

​
Step 2: Fix errors

Captions are AI-generated, so names, niche terms, and unusual words sometimes need fixing.
  • Tap any word in the captions to edit the text
  • Fix timing by dragging the start/end handles in the timeline
  • Add missing captions by scrolling to a blank area, tapping Add, and typing
→ Edit Spelling & Timing · Adjust Timing

​
Step 3: Style your captions

This is where you make your captions stand out.
1

Open the Style panel

Tap Style in the caption editor to browse presets. There are dozens of styles, from clean minimal text to bold animated captions.
2

Pick a style

Scroll through the options and tap to preview. The style applies to all captions in your video.
Bold, high-contrast styles (white text with a dark outline or background) tend to perform best on social media because they’re readable on any background.
3

Customize the style

After choosing a preset, you can adjust:
  • Font and size
  • Color (text and background)
  • Position: drag captions anywhere on the frame
  • Word effects: highlight the active word as it’s spoken
→ Word Effects · Move, Resize & Rotate

​
Step 4: Animate with Keyframes (optional)

Want your captions to move or animate across the screen? Use Keyframes to set a start and end position. Captions handles the animation between them. This works especially well for hook moments at the start of a video, or to guide the viewer’s eye to important words. → Using Keyframes for Dynamic Captions

​
Export

Tap Export when you’re happy with the result. Your captions are burned into the video, so no separate subtitle file is needed.

​
Tips

  • Shorter lines read faster. Captions that break at natural speech pauses are easier to follow than long lines.
  • Check your captions on mobile. What looks good in the editor may be too small on a phone. Preview on your device before posting.
  • Use word effects for emphasis. Highlighting the active word keeps viewers tracking the caption even at faster speech rates.
