The REC OUT is the recording output path. It is connected to an
external recorder where the images are stored. Its frame rate can only
be set to standard speeds. The REC OUT frame rate must match the
Sensor frame rate! If the REC OUT frame rate is lower than the sensor
frame rate, the images cannot be output as fast as they are created by
the sensor, resulting in dropped frames which are irretrievably lost!
If the REC OUT frame rate is higher than the sensor frame rate,
duplicate frame rates are output on the REC OUT. For example, if the
sensor is running at 10 fps and the REC OUT is set to 30 fps, every
image is output 3 times, resulting in two duplicate frames following
every active frame.
Note: ALEXA does currently not support Variframe recording!
The recorder would record these duplicate frames, which have to be
removed in post.
The MON OUT should match the sensor and the REC OUT frame rate.If
the sensor frame rate exceeds the available MON OUT frame rates, set
the MON OUT to half the sensor frame rate if possible.
How to correctly set frame rates:
• Decide which frame rate you want to set
• In the Homescreen of the camera display, press the FPS screen
button.
• In the Fps screen, press the REC OUT screen button. This opens
the REC OUT menu screen.
• Set the REC OUT frame rate to the desired value. The HD-SDI
format should match the recorder's setting
• If the desired sensor frame rate is a standard speed, set "Link
sensor fps" to "On". This way, the sensor always follows the REC
OUT frame rate, avoiding dropped or duplicate frames.
• When the REC OUT settings are done, press BACK to load the
Sensor Fps screen.
• In the Sensor Fps screen, decide if the MON OUT frame rate is
OK. If not, press the MON OUT screen button. this loads the MON
OUT menu screen.
• Set the MON OUT frame rate to the desired value. If the sensor
frame rate exceeds the available MON OUT frame rates, set the
MON OUT to half the sensor frame rate if possible.
• When the MON OUT settings are done, press the BACK button to
load the Sensor fps screen.
• Choose the desired sensor fps value from the list and press the
jogwheel.
• If the desired value is not available, press the ADD screen button
to set the desired value and add it to the list by pressing the
jogwheel.
