## What is Screen Check?

See the intended shot while there is still time to adjust the setup.

Screen Check – Green Previs brings live green-screen and blue-screen previsualisation together with practical planning tools for film crews. Preview your performer against a background, inspect the key, and explore framing and lighting before recording a previs take.

LIVE PREVIS
• Preview green-screen and blue-screen composites.
• Use Smart Background for a person-focused preview without a physical screen.
• Choose preset backgrounds or import your own photo and video plates.
• Fine-tune key strength, edge softness and despill.
• Inspect the preview with matte views, waveform and false-colour tools.

PLAN THE SETUP
• Estimate camera coverage, screen spill and lighting evenness.
• Explore sensor sizes, focal lengths and framing.
• Work with metric or imperial measurements.
• Save setups and organise scenes for the shoot.

RECORD AND SHARE
• Record previs takes with optional scratch audio.
• Save and share stills, recordings and production reports.
• Export camera-track information for post-production workflows.
• Share the live composite with another iPhone or iPad using Director’s Monitor.

PROCESS ON YOUR DEVICE
Camera processing and supported AI Set Review run on device. Screen Check does not upload your footage to a developer-operated service. You control when to export files or share a monitor feed.

REQUIREMENTS
Requires iOS or iPadOS 26 or later. LiDAR features require supported hardware. AI Set Review requires a compatible device and an available Apple Intelligence on-device model; some features require newer system versions. Live camera capture and tracking require physical devices.

Director’s Monitor requires another device running Screen Check and a reachable local or peer-to-peer network. The current monitor connection has no transport encryption or pairing code. Use a trusted network and stop sharing when finished.

Screen Check is a previsualisation and estimation tool. Results depend on your device, subject and setup, and should be checked against your production requirements.
