hzwer/ECCV2022-RIFE

Implements optical flow-based frame interpolation using an intermediate flow estimation network that operates at 30+FPS for 2X 720p video on consumer GPUs, supporting arbitrary fractional timesteps between frame pairs. The architecture uses a multi-scale flow predictor with cost volume refinement, enabling efficient real-time inference without per-timestep retraining. Integrates with video processing pipelines via CLI tools, Docker, VapourSynth plugins, and ncnn-Vulkan backends for cross-platform deployment including mobile and game engine applications.
