The black hole is modelled by the Schwarzschild metric. The accretion disc is modelled by a volumetric disc following a Kepler velocity field and with blackbody radiation at virtually infinite temperature. The trajectory followed by the camera is calculated for an angular momentum grazing the photon sphere, and the axes of the camera are parallely transported.
The duration of the fall is realistic for a black hole of 30 000 solar masses, with a Schwarzschild radius of 100 000 km, and starting at a distance of 3 million km. The video stops when we hit the central singularity. I've slowed time down by a factor of 2x from 1:17 and then by a factor of 20 from 1:25 to get a better look at what's happening. We cross the horizon at 1:24, but it's impossible to perceive because nothing special happens at the horizon.
