The passage around this formula
Video inherits the same per-tile arithmetic and multiplies it by time. Google is again the most specific vendor to check, because Gemini’s video-understanding documentation breaks the rate down by component: at default media resolution, each sampled frame (taken at one frame per second) costs about 258 tokens and the accompanying audio track costs about 32 tokens per second, for a documented total of “approximately 300 tokens per second of video.” At the model’s low-resolution setting, the same second costs about 100 tokens — 66 for the frame plus 32 for audio [ 6 ] . In the notation above, that is . where t is duration in seconds, f the sampling rate, and…
