Outline

To address the high computational cost of long-duration video processing, this paper proposes a novel method called differential distillation. This method improves computational efficiency by retaining task-relevant information while removing redundant information. Based on this principle, the ViLAMP model, developed, processes long-duration videos with "mixed precision" through frame-by-frame differential keyframe selection and patch-by-patch differential feature merging. Keyframes retain complete information, while non-keyframes retain only the most important features, reducing computational overhead. Experimental results demonstrate that ViLAMP performs particularly well on long-duration videos, capable of processing ultra-long-duration videos of up to 10,000 frames on a single NVIDIA A100 GPU.

Takeaways, Limitations

Takeaways:
A novel method (differential distillation) that effectively addresses the computational cost problem of long-term video processing is presented.
Efficient implementation of mixed-precision processing through keyframe selection and feature merging.
Achieving cutting-edge performance even in ultra-long video processing
Efficient ultra-long video processing on a single GPU is possible.
Limitations:
Further research is needed to determine the generality of the proposed method and its applicability to other types of video data.
Further research is needed to optimize the keyframe selection and feature merging processes.
Optimized for specific GPU environments, so performance may degrade on other hardware environments.
