Support

BCut supports most common video formats (MP4, MOV, MKV, AVI, WebM). If your video fails to load:

• Make sure the file isn't currently open or being written by another app.
• Try re-exporting the file from your recording software if it may be corrupted.
• Very long files (>2 hours) may take longer to prepare — give it a moment.

Transcription accuracy depends on audio quality and the selected language.

• Make sure the correct language is selected before processing.
• Recordings with background noise, music, or low volume will produce less accurate results.
• Using a higher-quality AI model (larger size) improves accuracy, especially for non-English content.
• Providing a short prompt with relevant names or terms can also help.

BCut runs AI transcription locally on your Mac, which is CPU/GPU-intensive for long videos.

• Longer videos and larger AI models take more time — this is expected.
• If the progress bar is moving, even slowly, the app is working normally.
• Close other heavy applications to free up resources while processing.
• If the app is truly unresponsive (no progress for more than 10 minutes on a short clip), force-quit and try again.

If BCut crashes on launch or while processing:

• Make sure you're running macOS 10.15 (Catalina) or later.
• Try re-downloading the latest version from bcut.app.
• If the crash happens consistently with a specific video file, please send us that file so we can reproduce the issue.
• Check Console.app (Applications → Utilities) for crash logs mentioning "BCut" — attaching these to your support email helps us fix the issue faster.

Models are downloaded directly to your Mac and can be several gigabytes in size.

• Check your internet connection and make sure you have enough free disk space.
• If the download stalls, click Cancel and try again — downloads resume from scratch.
• If downloads consistently fail, a firewall or VPN may be blocking the connection. Try disabling it temporarily.
