Definition
Auto-generated captions use AI speech recognition (ASR / speech-to-text) to automatically transcribe spoken audio in a video and generate synchronized caption/subtitle tracks. Modern auto-captioning supports multiple languages and accents, speaker attribution, punctuation, and timing alignment. Captions are essential for accessibility compliance (ADA, WCAG), social media engagement (85% of Facebook videos are watched without sound), SEO (search engines index caption text), and reaching non-native speakers.
How Loopdesk Uses This
Loopdesk provides AI-powered auto-captioning in 108 languages with high accuracy across accents and dialects. Both Creator plans include monthly AI credits for caption generation, with pay-as-you-go top-ups when you need more. You can customize caption styling (font, color, size, position, animation), review and edit generated text before export, and choose from various visual styles. Captions are fully synchronized to your timeline and update automatically when you make edits.
