You tap auto captions, wait, and nothing appears. Or the captions appear with the wrong words, or they look perfect in the preview and vanish from the exported video. Caption problems in Edits are common, and they have a short list of causes, but the fix depends on which shape yours takes.
The key fact about auto captions is that they are generated on the server, not on your phone. That means they need a stable connection, and it means a server problem or a staged rollout can break them for you while a friend’s captions work fine. Knowing that saves a lot of wasted reinstalling.

30-second answer: Retry on stable Wi-Fi first, then check the caption language setting and that captions are turned on for the clip. If the captions generate but look wrong, the audio is unclear and the text needs a manual edit. If nothing generates on any project, it is usually a rollout or server issue, and waiting is the real fix.

What you are seeing
Caption failure has four shapes. Nothing generates at all, and the caption button spins or errors: that is usually connection or server. Captions generate with the wrong words: that is audio clarity, not a broken feature. Captions look right in the preview but vanish from the export: that is a caption toggle or a style problem. Captions work on some clips but not others: that is the audio on the failing clips.
Work out which shape yours is before changing anything, because the fixes do not overlap. A connection fix will not repair a wrong-words problem, and a style fix will not help a server outage. The shape tells you where to start, and starting in the right place is most of the job.
Likely causes, ranked
- No stable connection during generation. Auto captions are generated on the server, so a dropped or weak connection stops them cold, even when the rest of the app works fine.
- Wrong caption language. If the language setting does not match the spoken language, generation fails or produces nonsense.
- Unclear audio. Background noise, mumbling, overlapping voices, or a distant microphone all make speech recognition guess, and guesses become wrong words.
- Captions turned off for the clip. Captions can be toggled per clip or per project, and a toggle left off looks exactly like a failed feature.
- A style that hides the text. White text on a bright background, tiny text, or a style with no background can make captions invisible while they are technically present.
- Staged rollout or server outage. Caption features reach accounts in waves, and server faults can pause generation for hours. When nothing else explains it, this is the honest answer.
Fixes, quickest first
- Retry on stable Wi-Fi. Switch to a steady connection and generate the captions again from the start. Do not switch networks halfway through.
- Check the caption language. Confirm the language setting matches the spoken language, then regenerate. A language mismatch is the most common cause of nonsense text.
- Confirm captions are turned on for the clip. Open the caption controls for the clip and the project and make sure the caption layer is enabled, not just generated.
- Regenerate after trimming the noisy start. Cut long silences, wind noise, or music-only intros before the speech, then regenerate. Cleaner audio gives cleaner words.
- Fix the style, then re-export. If captions show in the preview but vanish from the export, pick a high-contrast style with a background, then export a short test clip before the full project.
- Update the app, then wait. Check the store for an update, install it, and try again. If it still fails on every project, move to the rollout section below rather than reinstalling.
- Reinstall only as a last step. Export any finished work first, because drafts stored only on the device are at risk when the app is uninstalled.
When it is a rollout or server problem
Caption generation is one of the features most affected by staged rollouts: a friend can have a new caption style or a working generator weeks before it reaches your account, and nothing you do on your phone speeds that up. Server faults have the same shape, except they usually clear within hours.
The test is simple: generate captions on a brand-new project with a short, clear voice clip on stable Wi-Fi. If that works, your old project is the problem. If that fails too, check our updates page for the latest status, then wait and try again later. Reinstalling during an outage fixes nothing and risks drafts.
Prevent it next time
Record speech close to the phone in a quiet room, one voice at a time, and generate captions before you add music. Music under speech is the fastest way to turn good audio into guessed words. Our captions tutorial walks through the full caption workflow, including manual edits.
Build a caption check into your export habit: watch the exported file in your photos, not just the preview, and confirm the captions are visible there. Catching a missing caption layer before you post is a ten-second check that saves a re-upload.
Caption styles that stay readable
Most vanishing captions were never missing. The words are in the video, but the style makes them unreadable against the background, and the viewer assumes they failed. White text with no background disappears over a bright sky, and thin text disappears over a busy street scene. The fix is contrast, not a new feature.
Choose a style with a solid background or a strong outline, keep the text large enough to read on a phone held at arm’s length, and keep each caption line short. Two short lines beat one long line that wraps and crowds the frame, and a caption that sits over a plain part of the shot reads better than one over a moving face.
Test the style on your actual footage, not on the style preview. Export a five-second test clip, watch it on the phone, and only then apply the style to the full project. A style that looks good in the picker and unreadable on your footage is the wrong style for that footage.
Still stuck?
If the fixes above have not worked, run the two-project test. Generate captions on a brand-new project with a short, clear voice clip, then try the same clip in the failing project. If the new project captions and the old one does not, the old project’s audio or settings are the problem, and rebuilding that project’s caption track is faster than fixing it.
If neither project captions, the problem is the connection, the account, or the server, and the honest next step is to stop reinstalling in a loop. Check for an update, confirm stable Wi-Fi, and try again later. Manual captions are the fallback that always works: type the key lines yourself, and the Reel ships on time.

Frequently asked questions
Why are my Edits captions not generating?
Usually the connection dropped during generation, or the language setting does not match the spoken language. Retry on stable Wi-Fi and check the language setting.
Why do my captions show the wrong words?
The audio is unclear, noisy, or heavily accented, and the speech recognition guessed. Edit the text manually and re-record unclear lines in a quiet room.
Why do captions disappear after export?
The caption layer was turned off for the export, or the style made them invisible against the background. Check the caption toggle and the style contrast before re-exporting.
Do captions work without the internet?
No, auto captions are generated on the server, so they need a stable connection. Record and edit offline, then generate captions when you are back on Wi-Fi.
Why does my friend have captions but I do not?
Staged rollouts: a feature can reach one account before another. If the checks above all pass, waiting is the real fix.
Should I reinstall Edits when captions fail?
Only after the quicker checks. Reinstalling is slow, risks drafts, and rarely fixes a caption problem on its own.

Manual captions when auto captions keep failing
When auto captions refuse to generate and the Reel has to ship, manual captions are not a downgrade, they are the reliable route. Type the spoken lines yourself as a text layer, timed to the speech, and the result is often more accurate than a guessed transcript, because you know what was actually said. The trade-off is time, not quality.
Work in short lines and place them as the person speaks, not as a wall of text at the start of the clip. A good rule is one short sentence per caption, on screen for as long as it takes to say it, and never more than two lines at once. Viewers read captions in glances while they watch the video, so a caption that stays up too long feels stale and one that flashes past feels broken.
Keep the style consistent with the rest of the Reel: the same font, the same size, and the same position, so the manual captions do not look like an afterthought. If the Reel already has auto captions on other clips, match their look as closely as you can, and keep the manual lines in the same part of the frame.
Manual captions also solve the wrong-words problem permanently for that clip, because nothing is guessed. If a name, a place, or a brand keeps coming out wrong in auto captions, type it once by hand and it stays right. For short Reels, manual captions are often faster than regenerating auto captions three times and editing every line afterwards.
