MoG is a generative video frame interpolation (VFI) model, designed to synthesize intermediate frames between two input frames.

MoG is the first VFI framework to bridge the gap between flow-based stability and generative flexibility. We introduce a dual-level guidance injection design to constrain generated motion using motion trajectories derived from optical flow. To enhance the generative model's ability to dynamically correct flow errors, we implement encoder-only guidance injection and selective parameter fine-tuning. As a result, MoG achieves significant improvements over existing open-source generative VFI methods, delivering superior performance in both real-world and animated scenarios.

# Usage

We provide two model checkpoints: `real.ckpt` for real-world scenes and `ani.ckpt` for animation scenes. For detailed instructions on loading the checkpoints and performing inference, please refer to our [official repository](https://github.com/MCG-NJU/MoG-VFI).
