Quick fix first. Before anything else, confirm captions are actually turned on for the project, and that the audio they should transcribe is audible — captions need clear speech to work from. If the audio is quiet, noisy, or missing, fix that first (see the no-sound guide), then regenerate the captions. If the audio is clear and captions still will not generate, work through the steps below in order.
Captions in Edits are generated from the audio on your timeline, so most caption failures are really audio problems, language problems, or rollout problems wearing a caption disguise. This guide tells those apart, because each one has a different fix — and because the fix for a rollout problem is patience, not reinstalling.

The symptom, precisely
Describe the failure exactly. Captions that never appear at all suggest the feature is off, the audio is unusable, or the feature has not reached your account. Captions that appear but are wrong suggest audio quality or language mismatch. Captions that appear on the timeline but vanish after export suggest an export or rendering problem. Captions that work on one project but not another suggest the second project’s audio is the difference. Note which pattern you have before changing settings.
Likely causes, ranked
- Audio too quiet, noisy, or missing. Transcription needs intelligible speech. Whispered lines, heavy background music, wind noise, or a muted clip give the caption engine nothing to work with.
- Wrong language selected. If the caption language does not match the spoken language, transcription produces garbage or nothing at all.
- Captions not enabled or generated for the project. Captions are a per-project step: opening a project does not automatically caption it, and a setting that was off stays off.
- A staged rollout. New or updated caption features reach accounts gradually, so the same app version can show captions for one creator and not another.
- An outdated app or corrupt cache. A bad update or damaged temporary files can break transcription until the app is updated or the cache cleared.
- An export problem. Least common: captions visible on the timeline but missing from the exported file, which points to rendering rather than transcription.
Fixes in order, quickest first
Test caption generation after each step. Stop when captions appear correctly.
1. Confirm captions are enabled and generated for this project. Open the captions tool in Edits and check that caption generation has actually been run on this project — not just that the tool exists. The captions tutorial walks through the full flow. If generation was never run, run it now; if it was run and produced nothing, delete the empty caption track and run it again.
2. Check the language setting. Confirm the caption language matches the language actually spoken in the video. Mixed-language videos are a common trap: transcription set to one language will mangle or skip the other. If your video mixes languages, generate captions for the dominant language first, then correct the remaining lines by hand.
3. Improve the audio before regenerating. Raise the volume of quiet speech, lower background music under dialogue, and remove or replace clips recorded in heavy wind or crowd noise. A cleaner audio track often fixes captions that looked like an app bug — transcription quality follows audio quality directly.
4. Test with a short, clear clip. Create a small test project with ten seconds of clear, loud speech and generate captions for it. If the test captions work, your app and account are fine, and the original project’s audio is the problem. If the test captions also fail, the problem is the app, the account, or a rollout.
5. Update Edits and clear the cache. Install the latest version from the official store, and on Android clear the app cache. Restart the phone, open the test project, and generate captions again. A bad update is a real cause of broken transcription, and this step rules it out.
6. Check the export separately. If captions show on the timeline but not in the exported file, export a short test and play it in your gallery. If the test export also drops captions, try exporting with captions baked in rather than relying on a separate caption layer, and confirm the captions are visible before sharing.
7. Use manual captions as a workaround. When automatic captions will not cooperate, add the captions yourself as text on the timeline — the text and titles guide covers styling text so it reads like captions. Manual captions take longer, but they are fully under your control, they work regardless of rollout status, and they are often more accurate than automatic transcription for names, slang, and technical terms.
8. Reinstall as a last resort. Export finished work first and accept that on-device drafts may be lost. Reinstall only after the test clip, the update, and the cache steps have all failed.
When captions are a rollout problem
Caption features are a frequent rollout case: the same app version can offer captions to one creator and not to another, and a feature that worked can change behavior after a server-side update. The signs are: the test clip fails too, other creators report the same failure at the same time, and nothing on your phone changed. When you see that pattern, check our updates page and use manual captions in the meantime — reinstalling will not speed up a rollout, and repeatedly regenerating captions on the same broken build will not either.
Keeping captions reliable
Record speech close to the microphone, keep music under dialogue rather than over it, and generate captions early in the edit — not at export time — so a failure leaves you time to fix the audio or switch to manual captions before a deadline.
Frequently asked questions
Why do my captions show on the timeline but not on Instagram?
First check the exported file in your gallery: if captions are missing there too, the export dropped them, and step 6 applies. If the exported file has captions but the posted Reel does not, the captions were likely a separate layer that Instagram did not carry over — export with the captions baked into the video itself so they travel with the file.
Why are my captions wrong even though the audio sounds clear to me?
Transcription is pickier than human hearing: accents, fast speech, overlapping voices, and background music all degrade it even when you understand every word. Slow down slightly, separate overlapping speakers, and lower music under dialogue, then regenerate. Always proofread automatic captions before posting — names and numbers are the most common errors.
Do captions work for every language?
Not necessarily. Caption support varies by language and by rollout, and a language that works for one creator may not be available to another yet. Test with the short clear clip in step 4: if captions fail in one language but work in another on the same clip, language support — not your phone — is the limit, and manual captions are the workaround.
Why did captions work last week but not now?
That pattern points to an app update or a server-side change rather than your project. Update to the latest version, clear the cache, and test the short clip. If other creators report the same break at the same time, it is a rollout or server issue: check our updates page and use manual captions until it is resolved.
Should I reinstall Edits to fix captions?
Only as a last resort. Most caption failures are audio quality, language, or a missing generation step, and none of those are fixed by reinstalling. Reinstall after the test clip, update, and cache steps have all failed — and export your finished work first.

If captions still fail after these steps, note the result of the short test clip — whether it captioned correctly, failed, or produced wrong text — because that single result separates an audio problem from an app problem from a rollout problem, and it is the detail that makes any further help useful.
Editing generated captions rather than regenerating. When captions are mostly right, edit the wrong lines instead of regenerating the whole track: regeneration can introduce new errors in lines that were correct, and it costs another processing round. Fix names, numbers, and technical terms by hand, then watch the captioned video once through to catch timing slips — a caption that appears a second late is nearly as confusing as a wrong word. This edit-first habit also protects you when generation is slow or flaky: one good generation plus careful edits beats five regenerations.
Why captions are worth the trouble. Many viewers watch Reels with sound off, and captions are what keep those viewers watching past the first seconds. A video whose captions fail is not just an accessibility problem — it loses a large share of its audience silently, because viewers who cannot follow the speech simply swipe away. That is why this guide recommends generating captions early and testing them on a short clip before a deadline: captions are part of the video’s reach, not a finishing touch, and a caption failure discovered at export time is a problem you no longer have time to fix well.
One last check before you post. Watch the finished video once from start to finish with the sound off and only the captions to follow — if you can understand the whole video that way, the captions are doing their job. If any line confuses you, fix that line before posting: viewers who watch muted will have exactly the same confusion, and they will not turn the sound on to resolve it. This silent watch-through is the fastest final quality check a captioned video has, and it catches timing and wording slips that reading the caption list alone misses.
Caption problems are frustrating precisely because they look like a broken feature when they are usually a fixable input: clearer audio, the right language, and one fresh generation. Work the list in order, and most caption failures resolve without any drastic step at all.
