Link: http://arxiv.org/pdf/2510.25772

1. 📘 Topic and Domain: Visual effects (VFX) video generation using AI, specifically focusing on reference-based dynamic visual effect generation in the domain of computer vision and graphics.
2. 💡 Previous Research and New Ideas: Based on prior work in video diffusion models and VFX generation that used one-LoRA-per-effect approaches; introduces novel in-context learning paradigm that allows a single unified model to handle multiple effects.
3. ❓ Problem: Current VFX generation methods require training separate models for each effect type and cannot generalize to unseen effects, limiting scalability and creative freedom.
4. 🛠️ Methods: Developed VFXMaster framework using in-context conditioning with reference videos, attention masking to prevent information leakage, and one-shot effect adaptation for handling out-of-domain effects.
5. 📊 Results and Evaluation: Achieved superior performance compared to existing methods across multiple metrics (FVD, Dynamic Degree, VFX-Cons), with particularly strong results in effect fidelity and generalization to unseen effects.
