Como resolver travamentos do Kaltura Capture na inicialização?
Kaltura Capture is widely used in universities, enterprises, and digital learning platforms for recording lectures, tutorials, and presentations. While the tool is loved for its ease of use and integration with Kaltura MediaSpace, some users face an annoying problem: Kaltura Capture freezing on startup. When this happens, the app refuses to launch, hangs on loading, or closes unexpectedly, preventing users from recording time-sensitive videos.
This article explains what Kaltura Capture is, how it works, common reasons it freezes, and—most importantly—effective ways to fix the startup freeze issue.

3. How to Resolve Kaltura Capture Freezes on Startup ?
When Kaltura Capture freezes at launch, it usually comes from a corrupted cache, outdated components, or conflicts with other apps. Below are the most reliable solutions.
3.1 Delete the Kaltura Capture Cache Folder
This is the most common fix. The cache often becomes corrupted after an incomplete upload or forced shutdown.
Windows:
Navigate to:
C:\Users\<YourUser>\AppData\Local\Kaltura\Capture\
Delete the entire folder named
Capturar
.
macOS:
Go to:
~/Library/Preferences/Kaltura/
Delete the
Capturar
pasta.
Restart Kaltura Capture.
3.2 Remove Temporary Session Files
Kaltura logs and temporary sessions sometimes create conflicts.
Delete these folders:
Windows:
%AppData%\Kaltura\Capture%LocalAppData%\Kaltura\Capture
Mac:
~/Library/Application Support/Kaltura/Capture
Then restart the program.
3.3 Reinstall Kaltura Capture Properly
Uninstalling doesn’t always remove old configuration files.
Passos:
- Uninstall Kaltura Capture
- Manually delete all remaining Kaltura folders
- Download the latest version from your LMS or MediaSpace
- Install fresh
3.4 Reset the Kaltura Configuration File
The config.json file stores device preferences. If corrupted, the app fails to boot.
Delete or rename:
- config.json in the Capture folder
Kaltura will recreate it on launch.
3.5 Disable GPU Hardware Acceleration Conflicts
Some older or integrated GPUs cause startup freezes.
Consertar:
Update your graphics driver, or force the app to run with the integrated GPU on laptops.
3.6 Close Background Applications

- Ampliação
- Teams
- Webex
- Estúdio OBS
- Gaming overlays (NVIDIA ShadowPlay, Xbox Game Bar)

Close these programs and relaunch Kaltura Capture.
3.7 Run as Administrator (Windows)
Some Windows environments require elevated permissions.
Right-click Kaltura Capture → Run as administrator .
3.8 Check For Missing System Permissions (macOS)
On macOS, the app may freeze if permissions weren’t granted.
