This is an optional macOS-only helper for true 10-bit exports when the browser can’t encode HEVC Main10.
How you use it:
1) Download the macOS app.
2) In Match Grade, click Desktop 10-bit Job to download cinematic_desktop_job.json.
3) Open the app, choose the job JSON, choose your source video, export 10‑bit.
Optional: export any LUT in 10‑bit
The desktop exporter can also apply any external .cube LUT (for example, a LUT generated in the Color Grade tool).
In the app, choose your Job JSON, then choose LUT Override and pick your .cube.

If macOS blocks the app
1) Make sure you drag the app out of the DMG into Applications.
2) Try: right‑click the app → Open.
3) If it’s still blocked: System Settings → Privacy & Security → Open Anyway.
Optional (Terminal): remove quarantine from the app you installed.
sudo xattr -dr com.apple.quarantine "/Applications/CinematicDesktopExporter.app"If your app is not in Applications, run the same command but use the real path to the .app.
