text: One Clip vs Multiple clips. We examine the impact of changing the temporal coverage of a model during downstream 
  evaluation on K400 action classification. In Table 14, we evaluate VideoMAE and V-JEPA models using an attentive 
  probe with access to either the feature map of 1 clip randomly sampled from the video, or the concatenated feature 
  map of 8 clips randomly sampled from the video. To sample 8 clips from a video, we first divide the video into 8 
  equal length temporal segments, and sample 1 clip at random from each segment. A single clip corresponds to 
  2 
  ≈ 
  seconds of a video on average, while 8 clips correspond to 
  16 seconds. The video encoders processes each clip 
  separately to produce a clip-level feature map, which are then concatenated at the input to the attentive probe.

  Increasing the temporal coverage from 1 clip per video to 8 clips improves the performance of both V-JEPA and 
  VideoMAE on K400 action classification. We therefore use the multiclip attentive probing setup as our default 
  evaluation pipeline.
