HY-Himmel Technical Report: Hierarchical Interleaved Multi-stream Motion Encoding for Long Video Understanding

Researchers introduce HY-Himmel, a hierarchical video-language framework that efficiently processes long videos by separating semantic and motion encoding tasks. The system uses sparse keyframes for visual grounding while a lightweight adapter extracts motion information from compressed video data, achieving better performance than dense-frame baselines while reducing token usage by 3.6x.

A Projection-Based Surrogate Gradient Interpretation for Neural Codec Wrappers

Researchers propose a new interpretation of surrogate gradients for training neural codec wrappers, showing that the SCALED method can be understood as a first-order approximation of video codecs. The technique enables end-to-end learning of pre- and post-processing networks alongside conventional codecs, achieving significant compression improvements of up to 23.59% BD-Rate reduction on x264.
