Screen recording stops unexpectedly? What to check
Find why a long screen recording stopped, check whether the clip was saved, and prevent another interruption with a few browser and power checks.
Your screen recording stops before the meeting, lesson, or walkthrough is over. Sometimes the recording file is still usable. Other times, the computer went to sleep, the shared screen ended, or the browser ran out of room to finish the file.
Use the Screen Recorder to make a short test and check each part of the setup before recording again. It records a screen, window, or tab, with optional system sound, microphone, and camera. It does not work on phones.
Check the recording setup
- Open the Screen Recorder on a computer and choose whether to capture a screen, window, or browser tab. Select the sound, microphone, or camera options you need.
- Make a short test recording, about 30 seconds. Speak or play sound if you need audio, then wait for the tool to finish producing the recording before leaving the page.
- Play the test file. Check that the picture and sound are present and that the recording lasts as long as expected.
- Before a longer session, check that the computer has free storage and will stay awake. Close apps and browser tabs you do not need.
- During the recording, keep the recorder page and the selected source open. Do not stop screen sharing from the browser's sharing controls.
A short test helps separate a problem with the capture setup from one that appears only after the computer has been recording for a while.
What the result means
The test ends when the computer sleeps or the display turns off
The computer may be entering a low-power state, even if you did not choose to stop recording. A sleeping computer cannot keep capturing. A display turning off does not always mean the computer is asleep, so check whether the recording itself ends, not just whether the screen goes dark.
The recording ends when you close a tab or stop sharing
The browser can end capture when the selected source closes or screen sharing stops. If you are recording a tab, keep that tab open. If you choose a window or screen, do not use the browser's sharing controls to stop the share.
The file is shorter than the session, or will not play
The browser or computer may have stopped before it could finish the recording file. Long recordings use storage and system resources. A nearly full drive, a busy computer, or a browser problem can interrupt capture or file creation.
The picture continues but the sound stops
The screen capture may still be running while a microphone or audio source disconnects. Check the microphone connection and permissions separately. If you selected a tab or screen with audio, confirm that the source itself is still playing sound.
How to prevent another interruption
- Keep the computer awake. On Windows 11, open Settings › System › Power & battery › Screen and sleep and set a longer sleep time while plugged in. On macOS, open System Settings › Lock Screen and set a longer display-off time. Check power-saving options in System Settings › Battery on a Mac laptop, and do not close its lid during a recording.
- Make space on the drive. Remove or move files you no longer need, then restart the browser before trying again. On Windows 11, check Settings › System › Storage. On macOS, check System Settings › General › Storage. Leave more room than you expect the recording to use, since file size depends on the content and recording settings.
- Reduce the computer's workload. Close extra tabs, video calls, games, and large downloads. A busy computer may struggle to capture and encode video for a long time. If the computer is hot or its fans are running hard, let it cool and try a shorter test first.
- Check the selected source. Start a new recording and choose the screen, window, or tab you actually need. Keep both the recorder page and the captured source open. If the browser shows a sharing indicator or controls, avoid selecting its stop-sharing option until you are finished.
- Reconnect audio devices. If the picture records but the microphone does not, check the cable or Bluetooth connection and select the intended microphone in the recording setup. On Windows 11, open Settings › Privacy & security › Microphone. On macOS, open System Settings › Privacy & Security › Microphone. Allow the browser if prompted.
- Review screen-capture permission on a Mac. If macOS blocks or interrupts screen capture, open System Settings › Privacy & Security › Screen & System Audio Recording and allow the browser. The wording can differ on older macOS versions. Quit and reopen the browser after changing this permission.
- Restart and update the browser. A fresh browser session can clear a stalled capture. Save any other work first, then update the browser through its own settings and repeat the 30-second test.
Why there is no single maximum recording time
A browser recording does not have one universal time limit that applies to every computer. How long it can run depends on the browser, available storage, memory, video content, and whether the computer stays awake. A screen with fast-changing video can also take more work to capture than a mostly still document.
For an important or lengthy session, use shorter segments and check each one before continuing. If a recording stops, wait for the tool to finish creating the file before closing the page. Recordings made with the Screen Recorder stay on your device, and nothing you record is uploaded.
