The passage around this formula

The documented token economics make the architectural claim concrete rather than rhetorical. Gemini’s video pricing bundles the visual and audio streams into one per-second cost: cvideo≈(f×τframe)+τaudioc_{\text{video}} \approx (f \times \tau_{\text{frame}}) + \tau_{\text{audio}}. where, at default resolution, the sampling rate f is one frame per second, each frame costs τframe\tau_{\text{frame}} ≈\approx 258 tokens, and the audio track costs τaudio\tau_{\text{audio}} ≈\approx 32 tokens per second — giving cvideoc_{\text{video}} ≈\approx 290 tokens per second, close to the approximately 300 tokens per second Google documents directly for default-resolution video [ 5 ] . The formula is unremarkable arithmetic, but what it exposes is the real assumption underneath the “native” claim: a single…
