Shu tter Spe ed
When operating in the default (Nor mal ) mode, the Shu tter Speed values are absolute and
independent of the capture frame rate.
This means as Shutter Speed decreases, more light falls on the sensor, increasing exposure
and motion blur on any objects moving within the frame. As Shutter Speed increases less light
falls on the sensor, decreasing exposure and motion blur on objects moving within the frame.
Spee d: Exposure times presets include: 1/24, 1/25, 1/30, 1/32, 1/33, 1/40, 1/48, 1/50,
1/60, 1/96, 1/100, 1/120, 1/125, 1/192, 1/200, 1/250, 1/384, 1/400, 1/500, 1/696,
1/800, 1/1,000, 1/1,200, 1/2,000th sec.
When operating at 23.98 or 24.00fps, these equal common shutter angles of
1/32nd 270 deg 1/96 90
1/48 180 1/192 45
1/60 144 1/384 22.5
Rela tive : When operating in this mode, the Shutter Speed values are proportionately reduced or extended to correspond to changes in the instantaneous capture frame rate. This
mode is analogous to use of a fixed shutter angle on a film camera.
e.g. Enabling Relative mode with 1/48th sec shutter at 24fps will mean 1/96th sec for 48fps,
and 1/16th sec for 8fps. This achieves the same visual result as setting a180 degree shutter.
Syn cr o: When operating in this mode, the Shutter Speed values may be proportionately reduced or extended to tune exposure time to a precise value. Range 10 – 90. Default 50.
e.g. Setting Syncro to 53 with a 1/60th sec shutter is equal to 1/56.6 sec exposure time.
Phase: provides a delay relative to the start of the frame for the exposure time. Phase may
be adjusted over the range - 45 to + 45 degrees. Default value is 0.
Note : T o Con ve rt Sh utter Spe ed t o Angle Equi valent
Equivalent Degrees = (Shutter Speed x Project Frame Rate x 360)
e.g. = 1/48 x 24 x 360) = (8640 / 48) = 180
