(7) Frame Rate and Shutter for Recording Parameters (Camera Details or List of Camera
Settings)
Sets the frame rate and shutter in HX, GX and Q cameras so the next exposure pulse (sync
signal) doesn't arrive during sensor exposure. With fx cameras, sets the frame rate to
double or more the speed of the sync signal.
(8) EST Recording
After setting the aforementioned, turns the camera to VIEW/ARM.
■ VIEW during EST Recording Settings
During EST recording settings, the GX camera drives the sensor with external sync signals
when in VIEW. If there is no external sync signal during VIEW, select “OFF (Internal Sync)”
with “HX, GX EST VIEW Sync” in “Sync Settings” of “Options” or “Camera Connection
Settings”.
With fx cameras, the sensor is driven by internal sync signals when in VIEW. The fx camera
can display the image even without external sync signals when in VIEW and the captured image
is not synced to the external sync signals so if using a strobe light, the image with the same
brightness as the recording cannot be confirmed.
■HX and GX-8 A-EST Sync
With HX and GX-8 cameras, “A-EST Sync” is available in addition to “Internal Sync” and
“EST Sync” in “Sync HX, GX Cameras”.
A-EST sync sets synchronization to EST signals that is more precise than EST synchronization.
To use A-EST sync, select “A-EST Sync” in “Sync HX, GX Cameras” under “Sync Settings” in
“Options” or “Camera Connection Settings”.
Specify in “Sync Cameras” under the “Recording Parameters” tab in the “List of Camera
Settings” window.
With A-EST, if the EST signal interval is double or less that of the exposure
time, the brightness of the image may fluctuate and there may be horizontal
noise.
With HX and GX-8 cameras, if external sync recording when the “Sync GX Camera” is
set to “EST Sync” or “A-EST Sync”, the trigger resetting function does not work. If
“GX Camera Time” is set to “Reset Trigger”, that setting is disabled and the “GX
Camera Time” functions as “Camera Internal Time”.
When using “A-EST Sync”, the “Exposure Timing” setting is disabled and it functions
as “GX Native”.
