Elephant in the Fridge: Constant-Memory Frame Packing for Long Video Understanding

Shuo Gao, Chenhao Zheng, Zhongzheng Ren.

What does this repo contain?

This repo contains:

• Offline CLIP scores: Relevance between each frame and text query, calculated by CLIP-ViT-B/32.
• Offline frame feature: Visual feature extracted by CLIP-ViT.

How to use it?

To avoid massive online calculating, you can download these data and put these offline scores and feature in the local/ directory of the repo, or download wherever you want and link them to this directory.

Unzip the clip_scores.zip and frame_feature.zip file by this script:

unzip /path/to/clip_scores.zip
unzip /path/to/frame_feature.zip

Now you can run the evaluation on LongVideoBench, MLVU and VideoMME with their pre-calculated frame feature.
