Why am I getting "Unable to process audio" errors during lipsync?

Last updated: March 10, 2026

Context

You may encounter audio processing errors when using the lipsync feature in Sync. These errors typically appear as "Unable to process audio. Please try again with different audio" or "Unable to process audio file. The file appears to be corrupted or improperly encoded."

Answer

This issue has been largely resolved with recent fixes pushed by the development team. However, if you're still experiencing problems, here are the steps to troubleshoot:

  1. Check your audio format: Ensure your audio file is in a supported format. Convert your audio to MP3 or WAV format if needed. You can find the complete list of supported media formats in the compatibility documentation.

  2. Verify audio file integrity: Make sure your audio file is not corrupted. Try re-exporting or re-encoding your audio file.

  3. Check lipsync settings: If you're using the "lipsync only the active speaker" option with multiple characters in your video, try unchecking this setting. This can resolve issues when some characters (like those with helmets or robots) cannot be properly processed for lipsync.

  4. Try a different audio file: Test with a simple, known-good audio file to determine if the issue is file-specific.

If you continue to experience this error after trying these steps, please contact support and provide your job ID or the specific audio file you're trying to use so the team can investigate further.
