Hi, thanks for your great job! I notice that there are two ways to load the video data: 1.extrated frames 2. on-the-fly decoding Could you please provide some details about the difference in their loading speed? And how much memory space will the extracted frames take up (e.g. K400)?

Hi, Minghao,

Thank you for your interest in our work. I haven't specifically tested the speed of the two loaders, "extracted frames" and "on-the-fly decoding," in this context. In fact, all models discussed in this paper were trained using extracted frames. However, if you are using a solid-state drive (SSD), the speed difference between the two loaders may not be significant. If you choose to use extracted frames for training, it would require approximately 1 T of disk space for the K400 dataset.

Thank you for your reply, your advice is helpful to me!
