Temporal Coherence And Motion Smoothing

via “modular motion module-based temporal coherence enforcement”

[TPAMI 2025🔥] MagicTime: Time-lapse Video Generation Models as Metamorphic Simulators

Unique: Implements temporal coherence as a modular component operating on latent representations during diffusion sampling (not as post-processing), using optical flow constraints to enforce smooth motion and appearance consistency across frames while preserving the ability to generate significant visual transformations.

vs others: More principled than frame interpolation or post-hoc smoothing because temporal constraints are applied during generation rather than after, preventing artifacts and ensuring that the model learns to generate temporally coherent sequences rather than fixing incoherence retroactively.
