The "Proxy Creation Failed" message in Capture One is a known issue that can affect various workflows. This error can appear for various reasons, including corrupted files, permissions issues, or catalog inconsistencies. This guide walks you through key troubleshooting steps to help resolve it.

Grant Full Disk Access and Accessibility Permissions

macOS may block Capture One from reading or writing files if permissions aren’t set properly.

  1. Go to System Settings > Privacy & Security.
  2. Open both Full Disk Access and Accessibility.
  3. Use the + button to add your current version of Capture One if it’s not listed.
  4. Unlock the pane with your password or Touch ID if needed.
  5. Restart your Mac after saving changes.

 

Test Other Sessions or Catalogs

To determine if the issue is file-specific or related to your current working document:

  1. Create a new session or catalog.
  2. Import the same RAW files that caused the error.
  3. If the error doesn’t occur, your original document may be corrupted or overloaded.

Import Files from Internal Drive

Corrupted SD cards or external drives often lead to proxy creation errors.

  1. Copy your image files from the SD card or external drive to your Mac’s internal drive.
  2. Import the copied files into Capture One from the internal drive.
  3. If successful, the issue likely stems from the original media source.

Run Catalog Repair

Capture One can repair structural issues in catalogs that may interfere with proxy generation.

  1. Open Capture One.
  2. Go to File > Repair Catalog.
  3. Follow the prompts and wait for the repair process to complete.

Check Drives for Errors

File system errors or failing drives can interrupt proxy creation. Use Disk Utility to verify and repair all drives involved:

  1. Open Disk Utility on your Mac.
  2. Select your internal drive and any external or DAS drives where images are stored.
  3. Click First Aid and run it on each drive.
  4. Review any warnings or errors reported and take appropriate action.

Contact Support

If none of these steps resolve the issue, please provide Capture One Support a sample files:

  • Pack the affected RAW file as an EIP file (see: Sharing EIP Files).
  • Send the file through the secure upload link provided in your support ticket.

This helps our team diagnose the issue based on your specific file and setup.
