AI BriefingHow to Add Captions to Videos
Key point
This guide explains how to automatically add captions to videos using ElevenLabs' AI Caption Generator.
Details
Captions are a key factor in increasing retention for muted viewers, improving accessibility for hearing-impaired and non-native speakers, and enhancing content discoverability through platform search indexing.
ElevenLabs' AI Caption Generator uses the Scribe speech recognition model to generate captions with word-level timestamps in seconds. The tool distinguishes up to 32 speakers, supports over 90 languages, and can tag non-verbal audio events such as laughter or applause.
The caption generation process is as follows:
- Video Upload: Upload videos in various formats, under 10 minutes and 50MB
- Caption Generation: Scribe transcribes the audio and aligns timing per word to generate captions
- Review and Edit: Click on the transcribed text to edit, split/merge segments, and assign speaker labels
- Export and Apply: Import the caption file into editing software like CapCut or Premiere Pro to burn it into the video, or upload it as an SRT file via the captions tab in YouTube Studio
Uploading a manually generated file is more advantageous than using YouTube's automatic caption generator for improving the accuracy of proper nouns and technical terms, and videos with burned-in captions are more effective for short-form content like Shorts.
