How to Automatically Generate Video Subtitles with AI: A Step‑by‑Step Tutorial

Adding accurate subtitles to your videos is easier than ever thanks to AI-powered tools. Follow this tutorial to transform your raw footage into fully captioned content in just a few minutes.

  1. Prepare your video file or URL
    Have your video ready in MP4, MOV, or another common format. If it’s already on YouTube or a similar platform, copy the public URL.

  1. Upload or paste the URL
    In the Capsai interface, click Upload Video or Paste URL, then wait for the file to process. Processing time typically ranges from a few seconds to under a minute, depending on length.

  1. Select your subtitle language(s)
    Choose one or more languages - Hindi, English, Hinglish - or combine them for bilingual captions. Multilingual support ensures you reach viewers across regions.

  1. Review and edit the auto-generated text
    Once the AI completes transcription, use the built-in editor to correct any misheard words, adjust timing, or tweak formatting. Look for speaker labels, punctuation, and line breaks to enhance readability.

  1. Customize styling and format
    Decide whether you want downloadable SRT/WebVTT files or burned-in subtitles. You can also adjust font size, color, and on-screen positioning to match your brand.

  1. Download or export directly
    Click Download to save SRT or VTT files for later use, or select Burn Into Video to create a permanently captioned file. The burned-in option is ideal for platforms that don’t support separate subtitle tracks.

  1. Upload to your platform
    For YouTube, access YouTube Studio → Subtitles → Add Language, then upload your SRT file. For Instagram Reels or TikTok, use your edited, burned-in video to ensure captions display properly.

  1. Add metadata and optimize for SEO
    Include a transcript or caption summary in your video description and website embed. Search engines will index these words, improving discoverability for relevant keywords.

  1. Publish and monitor engagement
    Share your captioned video and watch for increases in view time, watch completion rate, and viewer retention. Subtitles often lead to higher engagement, especially when viewers watch on mute.

This AI-driven workflow lets you generate professional-quality subtitles without manual transcription, saving hours of effort and making your content accessible to a wider audience.
