Gaussian SplatKing vs GREYSET

Gaussian SplatKing is a capture app for Gaussian splatting and radiance field reconstruction. It produces reconstruction-ready input data for any downstream pipeline and, for LiDAR captures, refines camera poses and trains a Gaussian splat on the device. Capture • Photo and video fire the 0.5x ultra-wide and 1x wide lenses simultaneously. A single-lens (1x) option, with RAW (DNG) photo capture, is available in Settings. • LiDAR mode pairs ARKit depth with the 1x wide lens, writes native COLMAP files (cameras, images, sparse points) on-device, and shows the point cloud as it accumulates. • 4K/30 HEVC video with Standard and Max Fidelity modes; optional undistorted video exports. • Auto photo cadence for walk-through capture, with a selectable interval. • Manual controls applied to both lenses: ISO, shutter speed or shutter angle, white balance, exposure, AF Lock, manual focus distance, tap-to-focus; a minimum shutter speed. • Optional capture location metadata, off by default. • iPhone and iPad. Process • Pose refinement: after a LiDAR capture, camera poses are refined on-device (feature matching and bundle adjustment) and recorded in the export. Free for everyone. • Train Splat (SplatKing Pro): train a Gaussian splat from a refined LiDAR capture on the device. No upload, no account. Output is an .spz file with an in-app viewer. Export • Every capture is a zip with media, metadata, COLMAP files where applicable, and splatpack.json, shared through the Files app or the share sheet to any pipeline. • Session quality summaries and per-file quality flags. SplatKing Pro is a one-time purchase that adds focus peaking, an RGB histogram, capture presets, the capture-interval selector, and on-device training. Everything that is free today stays free, and Pro never changes free capture quality. Analytics are anonymous and, in regions that require consent, off unless you opt in. Capture content never leaves the device unless you share it.

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.
