You speak, but your voice arrives a moment after your face moves. Or you hear a tap sound half a second after the button is pressed. Audio out of sync is distracting for viewers and makes a good tutorial feel unprofessional. The good news: the cause is usually one of a handful of things, and most are easy to fix.
Find the type of sync problem
How the delay behaves tells you a lot:
| What you notice | Likely cause |
|---|---|
| Same small delay from start to end | Bluetooth mic or headphones, or a fixed offset |
| Starts in sync, slowly drifts apart | Phone under strain, variable frame rate, or a long recording on a weak device |
| In sync in the recorder, out of sync after upload or in another app | Export or conversion issue |
| Out of sync only after cutting or speeding up parts | An editing step |
Causes while recording
Cause 1: Bluetooth microphones and earbuds
Bluetooth audio always has some delay, because sound is compressed and sent wirelessly. Many earbuds also have a lower-quality mic mode when used for recording. This often gives a constant offset.
- Use the phone's built-in microphone or a wired mic for narration whenever possible.
- If you must use wireless, test a short clip first and listen for delay.
- Disconnect Bluetooth headphones if you are not using them, so the phone doesn't route audio through them by surprise.
Our guide to screen recording with your voice on Android covers mic choices in more detail.
Cause 2: The phone is overloaded
Recording screen, microphone, internal audio and a camera bubble at 60fps is a lot of work. If the phone can't keep up, it may drop video frames while audio keeps going, so the two drift apart.
- Close apps you are not using.
- Try 30fps or a slightly lower resolution on older phones.
- Keep the phone cool and avoid battery-saver mode during recording.
- Turn off the camera bubble if you don't need it for that video.

Cause 3: Very long recordings
Small timing differences can add up over an hour. Recording long lectures or gameplay in parts of 15 to 30 minutes reduces drift and also protects you if something goes wrong. The long screen recording guide has a full routine.
Causes after recording: export and editing
Cause 4: Export and conversion
Some phones record with a variable frame rate, which some editors and converters handle badly. If your video is fine inside your recorder but drifts in another app:
- Export directly from your recording app instead of converting the file several times.
- Use a common format like MP4 for sharing.
- Avoid sending the file through a chat app before editing; they often re-encode videos.
See video export settings explained for formats and frame rates that play well everywhere.
Cause 5: Editing steps
When you speed up a section or cut in the middle of a word, the audio and video of that section must be changed together. If you speed up only the picture, your narration will no longer line up. Our guide to speeding up boring parts explains how to handle audio when you change speed.
In Cinematic Recorder, edits are non-destructive. If something looks wrong after an edit, you can undo or adjust it without touching the original recording.
How to fix a recording that's already out of sync
- Measure the offset. Find a clear moment, like a tap with a click sound or a word you say while pressing a button. Note how far apart they are.
- Constant offset? Many editors let you nudge the audio track earlier or later. Shift it by the measured amount and check several points.
- Drifting? Fixing drift after the fact is hard. It is often faster to re-record the section, or re-record just the narration over the existing video.
- Test before posting. Watch the start, middle and end of the final export.
Prevent it next time with Cinematic Recorder
Cinematic Recorder records microphone and internal audio together (internal audio needs Android 10+), and shows a live mic level meter so you can confirm your voice is coming through before you start. The countdown gives you a moment to settle, and the floating controls let you pause between sections instead of making one giant recording. See all recording features.
FAQ
Why is my audio out of sync only with Bluetooth earbuds?
Bluetooth adds a delay because audio is compressed and sent wirelessly. Use the phone mic or a wired mic for narration.
Why does the sync get worse later in the video?
That is drift, usually caused by an overloaded phone or a very long recording. Lower the frame rate, close other apps, and record in parts.
My recording is fine on the phone but out of sync on my computer. Why?
The other player or editor may handle the file's frame rate differently. Export a fresh MP4 from your recorder rather than converting it.
Can I fix sync without re-recording?
A constant offset can usually be fixed by shifting the audio. Drift is harder; re-recording the narration is often quicker.
Use a wired or built-in mic, keep the phone relaxed, and record long sessions in parts. Those habits prevent nearly all sync trouble.
