Tracking Marker vs GREYSET

This app is intended to help post-production with screen replacements in film- and video-production. If you are reading this you will probably know what it is about. We decided to keep it as simple as possible. Current tested devices: • Iphone 6 or higher • Ipad 2 or higher. Enjoy.

GREYSET turns your iPhone into a real film camera for AI filmmaking. Point your phone, walk around, and operate a virtual camera inside your 3D previz scene — then export the camera move as a reference for AI video tools like Seedance, Kling or Veo. HOW IT WORKS • Open the GREYSET web app on your computer (greyset.app) and build a quick greybox scene — characters, props, action. • Scan the QR code with this app. Your phone becomes the camera. • See the live render from your computer right on the phone, framed exactly like the final shot. • Walk, pan, tilt — real handheld motion, captured in 3D. • Tap REC to record a take. The camera move lands in your scene, ready to export. FEATURES • Real AR camera tracking — your steps become dolly moves • Live viewfinder streamed from your desktop scene (or low-lag on-device AR preview) • Lens picker (16–135 mm), Handheld / Steadicam / Dolly movement styles • Joysticks for fine moves: truck, jib, pan & tilt • World scale 1:1 / 1:2 / 1:4 — shoot your set like a miniature for drone-style moves • Works offline too: AR demo scene + local take recording, no account needed GREYSET is built for filmmakers, DOPs and AI-video creators who want real camera language — not prompt roulette.
