Make an Instagram Reel accessible with captions

Instagram's caption sticker requires a creator to add it manually, so a meaningful share of Reels — including most reposts — have no captions at all, which is a real barrier for viewers who need them.

Transcribing the Reel's audio produces an SRT/VTT file for a caption track, plus a plain-text transcript for screen-reader users, who can't parse an on-screen sticker regardless of whether one was added. This is the same process whether the original had a caption sticker or not, since the output always comes from the audio.

  • Doesn't depend on whether the creator added Instagram's caption sticker at posting time.
  • SRT/VTT for a real caption track; plain text for screen readers, which can't read an in-video graphic.
  • Consistent process for brand/creator accounts standardizing accessibility across every Reel.

Instagram specifics

Typical length
Reels run roughly 15–90 seconds; feed video posts run longer, up to several minutes.
Worth knowing
Vertical 9:16 framing doesn't affect the transcript itself, since it's derived from the audio track rather than anything rendered on screen.

Best formats for accessibility

  • SRT a closed-caption track
  • VTT a closed-caption track for web players
  • TXT a plain-text transcript published next to the video, for screen readers

Workflow

  1. Transcribe the Instagram video.
  2. Export SRT/VTT and attach it as the video's caption track.
  3. Also publish the plain-text transcript on the page — a screen reader can read page text directly, but it can't parse a caption track embedded in a video player.

FAQ

The free tier includes 15 minutes of video a month, AI transcripts in any language, and TXT/SRT/VTT/JSON export — enough to run one Instagram video through and see the output before committing to anything.
