LTX v2v Analysis: Fine Geometry Collapse and Flat Surface Hallucinations
Relevant_Meat_9418 · reddit · 2026-08-23
Testing LTX-2.5 for video-to-video retexturing aimed at preserving CAD-accurate geometry revealed that while composition holds, fine periodic geometry (like vent slats) collapses or flips, and blank flat surfaces hallucinate controls. Extensive sweeps ruled out guide strength, resolution, and prompts. The author hypothesizes a VAE resolution limit (32x compression leaving too few latent cells for details) or insufficient conditioning signals, seeking data on actual VAE compression ratios and minimum feature sizes.
