Captions that move with your message.
Give your videos a voice that stands out on any platform. With automated captions in Air, you can dynamically render and customize styled text directly onto your video assets, making your content more engaging and accessible without needing external editing tools.
Air generates automated captions from the video asset’s transcript and permanently renders the styled text into every exported video frame. Unlike optional closed-caption or subtitle tracks, burned-in captions are part of the video image and remain visible wherever the video plays. Unlike the side-panel transcripts in the Video Intelligence tool, which are used for searching and reviewing text within your workspace, burned-in captions are permanently embedded into the video itself. This ensures your captions remain visible when you download the video or share it externally with clients.
Burned-in captions are useful for social media, marketing campaigns, and client presentations where videos are often watched on mute. By styling and rendering captions directly within Air, you can prepare your video assets for external platforms and ensure they work.
From asset modal
Burned-in caption rendering requires an eligible paid plan and consumes workspace credits for each render. For general information about workspace credit balances, see Explore Credits.
You can find automated captions in the Captions tab of the video asset viewer.
Output choices
After rendering, choose whether to download the rendered video, create it as a separate Air asset, or save it as a new version of the source asset. Download provides the rendered file, a separate asset keeps the result distinct in Air, and a new version places it in the source asset’s version stack. Captioned outputs saved to Air retain provenance associated with the render.

Air requires both a valid font and a valid variant before saving. When you change the font, Air selects an available default variant for that font. The controls below cover text appearance and placement, active-word highlighting, shadow, cue length, line wrapping, and timing.
Customization | Description | Options |
Size | Controls how large the caption text appears on screen, in points | 8-96 |
Color | Use color to set the color of the caption text. Depending on the style selected, the color will have a default selection. A color can be customized using a hex code or by clicking within the color swatch to modify. |
|
Position | Determines where on the video frame the captions are placed |
|
Drop shadow | Toggles a shadow effect behind the text to improve readability against busy backgrounds |
|
Highlight active word | Toggles emphasis on the word currently being spoken. When enabled, highlight color sets the emphasis color, and highlight lead adjusts its timing. |
|
Cue length: max words per cue | Limits how many words can appear in a single caption cue before it breaks into a new one | 1-24 |
Line wrapping: max chars per line | Limits the number of characters allowed on one line of a caption before wrapping | 10-80 |
Line wrapping: max lines per cue | Limits how many lines of text can display at once within a single caption cue | 1-4 |
Timing: max cue duration | Sets the maximum length of time (in milliseconds) a single caption cue can remain on screen | 500-15000 |

↩️ Reset
The circular arrow at the top of a style preset resets that preset’s controls to their default values, including font, variant, size, color, position, highlighting, shadow, cue length, wrapping, and timing.
🎛️ Customizations / Collapse
The sliders/toggle icon next to the reset button expand or collapse an individual style preset’s customization controls. Collapsing presets you are not reviewing keeps the panel focused while you compare styles.
