To determine the time needed to record a video clip to an SDI recorder, define the duration of the clip (Event Duration) and the Playback Rate. The SDI recorders are limited to specific rates. 720HD is usually 60fps and 1080HD is usually 30fps.

This program calculates the optimum focal point between two objects in the field. When the lens is focused to the optimum distance, the nearest and farthest objects of interest will have equivalent levels of sharpness.
Units are assumed to be the same for all values.
Distances are not measured from the end of the lens but rather from the image sensor. Many cameras use the Phi symbol for the image sensor/plane: φ

Solve Tilt from Hinge
Sets the tilt angle needed to put the focus-plane pivot (the “hinge”) at a chosen distance J in front of the camera: θ = asin(f / J). Most users don’t need this — use “Solve from scene” instead.

Tilt swings the plane of sharp focus off parallel (hinge rule J = f / sin θ) so a receding subject plane can be held sharp wide open. Shift slides the image circle across the sensor to correct converging lines or stitch a wider frame — watch the coverage margin so corners do not vignette.
