UnverifiedThe root cause of uncontrollable motion in text-to-video models lies in the ambiguity of text descriptions, which is an under-constrained problem that can be addressed by using 3D block-out constraints.71% similarUnverifiedThe core limitation of traditional image-to-video (I2V) technology is that a single image can only provide spatial information and cannot encode motion intent in the temporal dimension, forcing the model to rely entirely on text prompts to infer the direction and magnitude of motion.70% similarUnverifiedText-to-video models involve trade-offs among image sharpness, motion smoothness, and prompt adherence, with the technical root cause being competition between fine-texture parameters and motion-pattern parameters for model capacity67% similar
