+Egolearn video features.
+
+1. egocentric videos are extracted by VideoMAE_L14 at 8 fps.
+1. exocentric videos are extracted by InternVideo_MM_L14 at 8 fps.
+
+They are used for evaluating the egovideo-exovideo retrieval ability of [EgoInstructor](https://arxiv.org/pdf/2401.00789).
+
+Each file (e.g. 2cad4224-56c4-11ee-88ee-80615f12b59e.pth.tar) is a TxD feature vector, where T refers to the length of the video and D is 768.
+
+## 🏋️ How-To-Use
