Pre-FX & Digital Prop Tool
Free · In-App Purchases · Designed for iPad
The on-set prop tool built by filmmakers. Chroma keys, social simulations, custom UIs, and more. So your actors have something real to react to.
Stop losing production time to dead screens.
Prefx transforms your iPhone or iPad and any external display connected via USB-C/HDMI into a high-fidelity, interactive digital prop. Built by baffe, a creative production company, Prefx is the professional on-set tool designed to bridge the gap between live-set interaction and post-production precision.
Interactive Prop Themes
A library of fully customizable modules for every narrative need, governed by a global Clearance Toggle and tunable via the Signature Secret Menu.
• Stitch (Custom UI): Import your own designs or video plates to create a seamless, scrollable custom surface.
• Strike Up (Social Media): Scrollable feeds, profile grids, and realistic interactions for on-camera talent.
• Live Feed: Social broadcast simulation with looping video, scrolling comments, and animated viewer counts.
• Chatterbox: Scripted messenger simulations with adjustable reply timing, on-the-fly actor typing, and instant reset between takes.
• News: Scrollable digital news site with authentic headline and article layouts.
• CineVault: A high-fidelity VOD interface for "watching" content on-camera, now with full external display control, living where it was always meant to: your TV.
Clearance — Hero Mode vs. Villain Mode
One toggle flips every theme for legal clearance.
• Hero Mode: Platform-native typography and iconography for brand-consistent "good guy" devices.
• Villain Mode (True Neutral): 100% brand-neutral interface using open-source Inter typography and Lucide iconography, for antagonists or high-risk clearances.
Professional VFX Tools
• Chroma Key: High-visibility green, blue, and middle-grey backgrounds with optimized luminance for clean keying, fully supported on external displays so you can tune directly on the screen you're shooting against.
• Precision Markers: High-contrast markers for rock-solid matchmoving in After Effects, Mocha, or DaVinci Resolve, with full external display size support.
• Interactive Plates: Move tracking markers in real-time to simulate a live interface for the actor.
• UI Saturation: Desaturate interfaces on the fly to prevent color blowout on set cameras and specific LUTs.
On-Set Utility
• Emissive Lighting: Use any screen as a practical light source. Dial in color temperature with a Kelvin slider or use the RGB wheel for creative effects — now across any display size via external output.
• Status Bar Control: Set time, battery, signal, and wifi to exactly what the scene needs, across any theme, take after take.
• Privacy First: No data collection. No cloud processing. All assets stay local.
• Offline Ready: No internet required once installed.
• Global Support: Full UI in 12 languages.

Version 1.6.9 introduces Operator (Beta), a full fake phone OS built for on-set prop work. Pull up a convincing home screen, status bar, contacts, messages, and mail — all live on camera. Blackbox and Go timers let you fire on cue, and timed notification banners open directly into your saved Chatterbox conversations, keeping scripted interactions seamless and shoot-ready.
This update also patches a persistent timer crash that affected real device stability, fixes keyboard avoidance in the messages interface, and resolves CineVault poster accent color rendering and frame editor drag and face detection issues.
