text: Figure 7 V-JEPA training operates on a video clip flattened into a sequence of tokens. To convert a video clip of size 
  16 × 224 × 224 × 3 into a 1D token sequence, we apply a 3D convolution comprising d filters of size 2 × 16 × 16 with a temporal 
  stride of 2 and a spatial stride of 16, resulting in a tensor of shape 8 × 14 × 14 × d. Next we add absolute 3D sin-cos positional 
  embeddings to the spatio-temporal feature map and flatten it, resulting in a 1D token sequence of shape 1568 × d.
