The passage around this formula
…than merely adding up, and it is worth making explicit because it exposes an assumption rather than a vague sense of difficulty. A vision transformer front end tokenises an image of height H and width W at patch size P into = , and a video of T sampled frames multiplies that by T again. Any fixed context budget therefore forces a three-way trade between spatial patch size, temporal sampling rate, and clip duration — coarsen the patches, subsample frames, or truncate…
