AI filmmaking's spatial continuity problem: LTX 2.5 invents rooms when the camera moves
iJohnnyRobert · reddit · 2026-11-03
An LTX 2.5 user details the biggest pain point in general AI filmmaking: spatial awareness and continuity. When the camera moves, the video model 'makes stuff up' between keyframes — adding doors, windows, and objects that shouldn't exist — even when start/middle/end frames are provided. Reference images from GPT Image and Google Flow (Nano Banana 2) are themselves often spatially inconsistent, forcing fade transitions instead of continuous shots, and generating multi-angle views of the same location takes many retries. The poster asks whether full spatial continuity for sets is achievable without 3D-modeling every location — one setup that lets characters walk down the same street twice and have it look identical.
