Eliminating generative video drift, where AI-generated sequences degrade into incoherent shapes and logic after about 30 seconds

"current models trained on perfect data but generate imperfect images, each new frame relies on the prior so small errors compound until video collapses... overcome by error recycling: identify gap between generated frames/ ground-truth data, feed errors back into model during training, teach AI to recover from imperfections/ return to logical sequence... 2 outputs: open-source Stable Video Infinity generates stable/ high-quality videos lasting several minutes, LayerSync multimodal self-correcting internal logic"
