The studio compares configured camera settings using simplified source formulas. Its underwater branch requires both a water refractive index above one point zero five and positive depth. A flat guard in saltwater assigns magnification one point three three three and field constriction about twenty five percent. A dive dome assigns one and zero instead. At two hundred pixels per magnification unit, the two bars are two hundred sixty six point six and two hundred pixels. These are source assumptions, not tested housing performance, waterproof limits or a diving safety recommendation. Recording budget converts the configured bit rate from megabits to megabytes by dividing by eight. One hundred seventy megabits per second becomes twenty one point two five megabytes per second. Two hundred becomes twenty five, and one hundred thirty five becomes sixteen point eight seven five. At twelve pixels per megabyte per second, the bars measure two hundred fifty five, three hundred, and two hundred two point five. Usable card size is set to ninety three percent of the entered decimal gigabytes. A two hundred fifty six gigabyte card therefore uses two hundred thirty eight thousand eighty megabytes. At one hundred seventy megabits, dividing by twenty one point two five and sixty, then flooring, gives one hundred eighty six minutes. Real media rate and capacity may differ. The source computes stick and blind zone angles, but its invisible flag uses a separate diameter threshold. Diameter at most twenty four point five millimeters passes at any extension. A diameter up to twenty eight point five passes only when extension reaches one hundred centimeters. Compare a twenty eight millimeter stick at ninety nine centimeters and one hundred: the flag changes at the threshold, even though the geometry changes continuously. At three pixels per centimeter the extension bars measure two hundred ninety seven and three hundred. That boolean is a heuristic, not rendered seam inspection. The JSON manifest exports entered rig settings and derived numbers, rather than an actual camera video.
