The “Active Game” recording mode only records when Overwolf detects that you are in-game and the game is your active window.
You will see this message if you try to record your desktop while using this mode.

How to fix it:

1. Start your game, then press the Record button again.

2. Or change the setting in Overwolf:

   • Go to Settings → Capture

   • Change Record active game to Record monitor
     This will record everything displayed on your monitor, whether you’re in-game or not.

This message appears when the driver for your selected encoder is outdated.

If you’re using a hardware encoder (Nvidia NVENC, AMD AMF or Intel Quick Sync) update your GPU drivers:

• For Nvidia drivers, click here
• For AMD drivers, click here
• For Intel Quick Sync, click here

Restart your system after installing drivers. If you skip the restart, the error may continue.

Also verify that your graphics card meets Overwolf’s minimum recording requirements.

This error appears when your chosen combination of codec, preset, resolution and FPS is too demanding for your system.

What to do:

• Lower the recording settings until you find what works best for your PC.

• If possible, use a hardware encoder (NVENC, AMF, Quick Sync) since they reduce CPU load and allow for higher-quality recordings.

Overwolf does not have permission to create or save files in the selected location.

Solution:

Perform a clean reinstall of Overwolf.

Before uninstalling, back up your recording files if possible (If you're unsure reach out to the app developers for instructions: https://support.overwolf.com/en/support/solutions/articles/9000185804-support-for-3rd-party-apps) 

This appears when:

• The game is not supported by Overwolf (You can view a list of supported games Here.)

• The game is supported, but recording is disabled for it.

Check the supported games list to confirm.

Additional reason:

Some games use DirectX 8 (DX8) rendering, which Overwolf does not support for recording.

The drive selected in your recording settings has run out of space.

Solutions:

• Free up space by moving or deleting files.

• Change the target folder (Make sure to create a backup of your recording files before making any changes.)

  • Click the wrench icon on the video recorder

  • Under Video folder, select Browse or Change

  • Choose a new location

Overwolf cannot detect any available video encoder (hardware or software).

Fix:

Perform a clean reinstall of Overwolf (Back up your recordings before uninstalling.)

If the issue remains, contact us for assistance.

This message appears when an unexpected or unknown error occurs.

It shouldn’t happen, but if it does, please contact us and we’ll help you resolve it.

Due to technical limitations, Overwolf cannot record and stream at the same time.
We plan to add this feature in the future.

For now, choose either recording or streaming.

This appears when the recorder is already busy (for example, starting a new session).

Fix:

• Close the video recorder and reopen it, or

• Restart Overwolf

Only one Overwolf app can record at a time. You can find further information Here.
Stop the other recording app and try again. 

This can occur for several reasons, please try the troubleshooting steps Here.

If troubleshooting doesn’t help, please contact us for further assistance. 

The mf.dll file is required for Overwolf’s video recording to work correctly.
Windows N editions do not include Windows Media Player by default, which means this DLL is missing.

To fix this, download the Media Feature Pack for your Windows version:

• Windows 7 (Support was removed by Microsoft)
• Windows 8.1
• Windows 10

If you attempt to record using an unsupported sound format, Overwolf will show a recording error.
Switch to a supported audio format and relaunch Overwolf to resolve the issue.
