FFmpeg 8.1 for MuseScore Studio

Installers for MuseScore Studio 4.7 video export on Windows and macOS. These packages use the provider ID org.buanzo.ffmpeg8.1.

Downloads

Use these installers when MuseScore Studio asks for FFmpeg support. Only the MSI and PKG are linked here to keep the choice clear.

Windows / Microsoft Edge download warning: Edge may warn that the MSI "isn't commonly downloaded." That is a file-reputation warning from Microsoft Defender SmartScreen, not by itself a malware detection. Do not disable SmartScreen globally, and do not trust installers from unrelated sites. Keep the download only if it came from this page, has the exact filename below, and its SHA-256 hash matches the value listed here.

Platform Installer SHA-256
Windows 64-bit FFmpeg_8.1_for_MuseScore_Studio.msi 3f1a19d7278744674e9733600c833bf1719f85d89edec45dee5c8f2127f3c6e0

Verify the Windows Download

  1. Click the Windows MSI link on this page and wait for the browser download to finish.
  2. If Edge shows the "isn't commonly downloaded" warning, open the download item's menu and choose the option to keep the file. Microsoft documents this flow as Keep, Show more, then Keep anyway; exact wording can vary by Windows or Edge version.
  3. Do not point MuseScore Studio at an Unconfirmed *.crdownload file. That is a temporary browser download file, not the completed MSI.
  4. After the file is saved, confirm the filename is exactly FFmpeg_8.1_for_MuseScore_Studio.msi.
  5. In PowerShell, calculate the file hash: 
    Get-FileHash "$env:USERPROFILE\Downloads\FFmpeg_8.1_for_MuseScore_Studio.msi" -Algorithm SHA256
  6. Compare the result to this SHA-256: 
    3f1a19d7278744674e9733600c833bf1719f85d89edec45dee5c8f2127f3c6e0
  7. If the hash does not match, delete the file and download it again from this page.

Optional VirusTotal Check

You can upload the completed MSI or PKG to VirusTotal for an independent multi-engine scan. After upload, make sure the VirusTotal report is for the same SHA-256 hash shown above. A report for an empty file, a different hash, or a temporary .crdownload file is not evidence about this installer.

VirusTotal file reports are identified by SHA-256. The public reports for these installers are:

Do not treat VirusTotal as a permission slip for arbitrary downloads. Use it together with the source URL, filename, and SHA-256 comparison. If security software reports the file as malicious, stop and ask for help instead of forcing the install.
