You exported, opened the file, and there is nothing on the audio track. Before you re-export with different settings, it is worth knowing what CapCut itself says about missing sound — because the little the official documentation does say points at your source files and their formats, not at the export panel.
What CapCut's documentation actually covers here
The help center page closest to this problem is "Why Is the Audio Not Playing in CapCut?" (capcut.com/help/audio-not-playing, updated 24 March 2026). Two of the causes it lists are worth quoting exactly, because they are the ones third-party articles paraphrase into something CapCut never said.
It is also worth knowing what is not there. CapCut's help center documents no audio export settings at all — no sample rate, channel layout, audio bitrate or audio codec option, and nothing about exporting audio only. If you are hunting for an "audio quality" dropdown to blame, check the official documentation for what your version's export panel actually offers rather than assuming one exists.
The two causes CapCut states in its own words
"Some imported videos may not contain audio, especially screen recordings or compressed files."
"Certain audio formats may not be fully compatible, leading to playback failure."
Note how heavily both are hedged. "May not contain audio", "may not be fully compatible" — CapCut is describing possibilities, not diagnosing your project. Any article that turns these into "CapCut strips audio from screen recordings" has added a certainty the source does not carry. What they do point at is the source file and its format.
Start with the one nobody checks: does the clip have audio at all?
The first quote is the blunt one — "Some imported videos may not contain audio, especially screen recordings or compressed files." Screen recordings and compressed files are the two examples CapCut names, and they are named together, not ranked.
Settle this before anything else: a file with no audio stream has no sound to put on the timeline in the first place. The fastest test is to pull the audio out of the original file. If an extractor returns nothing, there is no audio stream — answered in seconds, before you spend twenty minutes on volume sliders.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
This runs inside your browser tab: the file is read from disk and processed locally, so a private screen recording is not uploaded anywhere. If an MP3 comes back with real sound in it, the audio exists and the problem is somewhere in CapCut. If the tool has nothing to extract, you need to re-record or re-export the source with audio enabled.
Check what your export range actually includes
If you exported a section rather than the whole timeline, the range itself is worth re-checking. CapCut's page on exporting part of a video explains: "If you only need to export a specific section of your video instead of the entire timeline, you can use In and Out markers to define the exact range you want to export."
The documented steps are to press Shift + X, then "Move the playhead to where your clip should start and press I to set the In marker" and "Move the playhead to where your clip should end and press O to set the Out marker." CapCut adds: "(You can press I and O in any order.)"
The page does not say which platform this applies to — only "on your keyboard" — so do not assume it is desktop-only. Whatever range those markers define is what lands in the file.
Format problems: the extension is not the format
CapCut's second quoted cause stays general — "Certain audio formats may not be fully compatible, leading to playback failure" — and it does not name a specific codec on that page, so treat any list of "bad codecs" you find elsewhere as unattributed unless it cites CapCut directly.
What CapCut does publish is a table of common supported formats. On the audio side it lists MP3, AAC, WAV, M4A and FLAC — with FLAC carrying the note "supported in some versions". The table is headed "Common Supported formats", not a complete whitelist, and CapCut adds: "Availability may vary depending on your device, operating system, and CapCut version. We recommend keeping CapCut updated to the latest version to ensure the best compatibility."
The more useful line comes from the same page: "CapCut supports a range of common video and image formats, but some formats or encodings are not supported at the moment. Even if your file is labeled as MP4 or JPG, its actual format may not match the extension, and therefore cannot be recognized by CapCut."
The word to notice there is encodings. CapCut is saying the container can be right while what is inside it is not — which is exactly the case where a file looks like an ordinary .mp4 and still misbehaves. Renaming does not help either: "Simply renaming a file's extension (for example, changing another format to '.mp4' or '.jpg') does not change the actual file format. As a result, the file may still fail to import into CapCut."
CapCut's own recommended fix is conversion, in its words: "Use a trusted third-party transcoding or conversion tool," then "Convert the video or image into a format supported by CapCut," then "Import the converted file into your project and continue editing." Its page on video not showing gives the PC version of the same advice: "Reimport the video file or convert it to a common format, such as MP4." For a QuickTime file from a Mac or iPhone, MOV to MP4 handles that in the browser; for a standalone audio file CapCut's table does not name, OGG to MP3 and FLAC to MP3 land you on MP3.
CapCut's two format lists do not match each other
One thing worth knowing before you trust any format list: CapCut's own site gives two different ones. The help center table above lists five video formats — MP4, MOV, AVI, MKV and M4V. CapCut's online video converter product page, on the same domain, says: "CapCut free video converter supports a wide range of imported formats, including MP4, 3GP, MPEG, MOV, AVI, WMV, FLV, and more," and elsewhere on that page, "It supports 1000+ formats including MP4, MOV, and WebM while maintaining original quality."
Those are claims about different things: the product page is marketing copy for the online converter tool, while the help center table documents the editor. When the two disagree, the help center table is the one written about importing into CapCut — which is why a file "CapCut supports" according to one page can still fail to import according to another.
What CapCut does not document about audio
Across CapCut's help center there is no published information on audio export parameters, on which specific encodings are supported or unsupported, or on whether CapCut re-encodes imported media. If a guide gives you exact answers to those, it is not getting them from CapCut.
How to tell it worked
Play the exported file outside CapCut. CapCut makes this point for image quality on mobile — "Play the exported video on a computer or external player—not just in the CapCut app—to confirm true quality" — and the same habit removes the app from the equation for sound.
If the exported file has audio in an external player, you are done. If it does not, go back to the source-file test above: no export setting can add an audio stream that was never in the clip. Other export symptoms have their own official answers — see CapCut export failed in the browser and CapCut export error codes.
FAQ
Why does my CapCut video have no sound after exporting? CapCut's help center page on audio not playing states that "Some imported videos may not contain audio, especially screen recordings or compressed files," and that "Certain audio formats may not be fully compatible, leading to playback failure." Start by extracting the audio from your source file to see whether it has any, and check that your export range covers the audio clip.
Does CapCut remove audio from screen recordings? CapCut does not say that. What it says is that "Some imported videos may not contain audio, especially screen recordings or compressed files" — the audio is often missing from the recording itself before CapCut ever sees it. Extract the audio from the original file to check.
Which audio formats does CapCut support? Its help center table lists MP3, AAC, WAV, M4A and FLAC, with FLAC marked "supported in some versions". The table is headed "Common Supported formats" rather than a full list, and CapCut notes availability varies by device, operating system and CapCut version.
Can I change audio bitrate or sample rate when exporting from CapCut? CapCut's help center does not document any audio export settings — no sample rate, channels, audio bitrate or audio codec options appear on the official pages. Check the official documentation for what your version's export panel offers.
Will renaming my file to .mp3 or .mp4 fix the import? No. CapCut states that renaming an extension "does not change the actual file format," so the file may still fail to import. Convert it properly instead — see all Clapr tools or the rest of the fix guides.
