Capsai Tutorial: Auto-Generate Captions for Reels & Shorts

  1. visit capsai auto subtitle generator
    go to https://capsai.co/auto-subtitle-generator in your browser

  2. upload your reel or short
    click upload video to select your mp4 file or paste your instagram/tiktok/youtube short url

  3. choose your subtitle language
    from the language dropdown select the language you want (for example hinglish, hindi or english)

  4. start the auto-generation process
    click generate subtitles and wait a few seconds for capsai’s ai to transcribe and time‑sync your captions

  5. review and refine in the editor
    use the inline editor to correct misheard words, adjust punctuation, split long lines at natural pauses, and ensure each caption stays under two lines

  6. fine‑tune timing for perfect sync
    drag the start and end handles on each caption to align precisely with the spoken audio or key visual moments

  7. customize styling if needed
    if you plan to burn‑in captions, tweak font size, color, and add a semi‑transparent background or outline so text remains legible on mobile screens

  8. export your final output
    choose download srt to get a standalone subtitle file or select burn into video to export an mp4 with embedded captions

  9. upload to your preferred platform
    for instagram reels and tiktok use the burned‑in mp4; for youtube shorts upload the srt under subtitles in youtube studio

  10. preview and publish
    watch your captioned reel or short on both ios and android to confirm timing, readability, and placement before sharing with your audience
