How to Add Subtitles to Instagram Reels

To put subtitles on an Instagram Reel you have two real options: use Instagram's own captions tool inside the app, or make the words yourself and burn them into the video with an editor before you upload. Scriptorium can do one useful part of the second route: turn the video's audio into a transcript or SRT file you can use as the text source. It does not add captions to video, and it does not connect to Instagram. This guide is honest about both, and about what we could not check.

What we could and could not verify

Instagram's help pages did not load as readable text for our checking tools, and search returned third-party guides rather than Instagram's own pages. So we cannot quote Instagram on the following, and we will not pretend to: the exact name and location of its captions tool, which languages it covers, whether it can be edited after you post, and whether a Reel can accept an uploaded SRT or VTT file. Check Instagram Help for the current rules on all of those. Third-party guides disagree with each other on the SRT question, which is a reason to test in the app, not to trust a blog, ours included.

Route 1: Instagram's own captions

Instagram has an automatic captions feature for Reels, which turns the speech in the video into on-screen text. We have not verified its steps on Instagram's own page, so open the Reel editor, look for the captions option, and check Instagram Help if you cannot find it. Whatever it produces, read every word against the audio before you post: names, numbers and anything said quickly are the common errors, which is true of every automatic tool, ours included.

• Strengths: it is built in and needs no other tool.
• Weaknesses: you are limited to what the app offers in style, language and editing, and you cannot take the text out as a file you keep (we could not confirm otherwise).

Route 2: a transcript as the source, captions burned in by an editor

Burned-in (open) captions are part of the picture itself, so every viewer sees them whatever their settings. Making them needs a video editor: CapCut, DaVinci Resolve, Premiere and similar tools can place text on video. We do not render captions into video. What we can do is supply the text.

1. Get the Reel's video file: the original export from your phone or editor, not a screen recording of the app. Scriptorium needs the file; it cannot take a link, an Instagram URL or your account.
2. Upload it to video to text. The no-account preview takes one file at a time, up to 15 minutes and 25 MB, with 3 tries a day, and deletes the file after 24 hours. Set the language, or use detection (33 languages available).
3. Correct the transcript. For short-form video, line breaks matter more than usual: shorter lines read better. See transcribing short-form video.
4. Export SRT, or plain text if your editor wants pasted words. We export TXT, timestamped TXT, SRT, VTT, Markdown, JSON and CSV.
5. Import the SRT into your editor if it supports SRT import (check its help), or paste the lines, then style and place them away from the area Instagram's own buttons cover.
6. Export the finished video with the captions in the picture and upload it as your Reel.

Should you upload an SRT to Instagram instead?

We could not verify that Reels accept a separate subtitle file, so we do not claim it. If you want to test it, do so on a private or draft Reel and see what the app offers; if there is no option to attach a file, you have your answer. Meanwhile, the route that always works is the one that does not depend on Instagram accepting a file: burned-in captions from an editor, or Instagram's own tool. SRT and VTT are explained in SRT vs VTT if you do reach a platform that takes subtitle files.

Practical tips for Reels captions

• Read them with the sound off. If the Reel is not understandable that way, shorten the lines.
• Keep text away from the bottom and edges, where the app's buttons and caption line sit.
• Check names and numbers twice; a wrong number on screen is worse than a missing one.
• Keep an editable copy of the text so you can fix a typo and re-export.
• If the audio is in Arabic or another language, set that language and review closely; automatic captions on dialect speech need a human check.

What we do not do

We do not add captions to a video, so a ready-to-post Reel with captions still needs an editor. We do not connect to Instagram, take links, or post for you, and we have no API. What we offer is the transcript step, which is also covered for general video in how to add subtitles to a video.

A review checklist for caption text

• Names of people, brands and places match how they are written elsewhere.
• Numbers, prices and dates match the audio exactly.
• No line carries more words than a viewer can read in the time it is on screen.
• Swear words, slang and dialect are written the way you intend, not as the recogniser chose.
• The captions do not cover the speaker's face, product or any on-screen text.

If you notice a mistake after posting, assume you cannot fix burned-in text: it is part of the picture, so you re-export and post again. That is a reason to review before you publish, not after.

If your editor has no SRT import

Many editors can import SRT, but not all, and import behaves differently between them; check your editor's help. If yours cannot, open the exported text file, copy a few lines at a time into the editor's text tool and set each one's start and end by eye against the audio. It is slower, but the timing in the SRT still tells you roughly where each line goes. For a 30-second Reel this is a few minutes' work. For a longer video, an editor with automatic caption import or Instagram's own tool will save time.

Why a transcript helps even if you use Instagram's tool

A transcript is also a record of what you said. You can search it, reuse it as a post caption or a blog paragraph, and check the on-screen text against it. Keeping the transcript is cheap insurance if you later re-edit the Reel.
