Captions & on-screen text
Subtitles: definition and examples
What is Subtitles?
Subtitles are lines of text displayed on screen that represent spoken dialogue, primarily to translate content from one language into another. On social video, they are common on multilingual channels or whenever a creator wants to reach audiences who speak a different language from the one used in the video.
When you'd use it
- 1When a video is recorded in one language and the target audience speaks a different language.
- 2When distributing a brand video across markets where localized text tracks replace a dubbed audio track.
- 3When a multilingual channel posts content in the creator's native language for an international following.
- 4When a campaign clip runs in a country where the spoken language differs from the majority language of the audience.
Example
A fitness creator shoots all content in English but wants to reach a Spanish-speaking audience in Mexico and the US. She exports the video with an SRT file, runs it through a translation service, and hard-burns the Spanish lines at the bottom of the vertical frame. The Spanish lines draw 40 percent of her total comments on that upload, from viewers who had never engaged with her English-language posts.
Use cases
- 1Adding translated text to a Spanish-language founder interview for an English-speaking audience.
- 2Localizing a product launch video into French and German text tracks for European distribution.
- 3Displaying translated dialogue lines on a clip from a brand event held in a foreign market.
FAQ
What is the difference between subtitles and captions?
Captions transcribe audio into text in the same language as the speaker, and are designed for accessibility including non-speech cues like [music] or [applause]. Subtitles translate dialogue into a different language and assume the viewer can hear the audio. On social platforms these terms are used loosely, but the practical difference is intent: accessibility versus translation.
How do I add subtitles to a short-form video?
Generate a transcript of the spoken dialogue, translate it into the target language, then either burn the translated lines into the video (open subtitles) or attach them as a separate SRT or VTT track the platform can toggle. Most editors and tools like CapCut, Premiere, and Bevyl auto-generate the transcript first, which you then translate and position inside the safe zone so the platform UI does not cover it.
What file format are subtitles?
The two most common subtitle formats are SRT (SubRip) and VTT (WebVTT). Both are plain-text files that pair each line of translated dialogue with a start and end timecode. SRT is the most widely supported across social and video platforms; VTT adds styling and positioning options used more often on the web.
Do subtitles help a video reach more people?
Subtitles widen the addressable audience by making a video understandable to viewers who speak a different language, which lifts watch time and shares from those markets. They also keep the video legible when it autoplays muted, so even within one language the on-screen text tends to improve retention, the signal the algorithm uses to decide how widely to distribute a clip.
