RIFLEx
RIFLEx enables training-free 2× temporal length extrapolation in video diffusion transformers by reducing intrinsic frequency components in positional encodings to prevent temporal repetition and slow motion artifacts. The method requires only a single line of code modification and achieves high-quality video extension from 129 to 261 frames without additional training.
