Only available on ALEXAs with XR module
If the desired frame rate cannot be set because it is grayed out, change
the codec to one with a lower data rate. For example, when using a 32
GB SxS PRO card and the ProRes 4444 codec, 60.000 fps will be
grayed out. Set the ProRes 422HQ codec to enable 60.000 fps.
There are shortcut buttons on the FPS screen for CODEC, INFO and SDI
FPS. In the SDI FPS screen, both MON OUT and REC OUT frame rates
can be adjusted within the limits of their current format.
Setting sensor fps through REC OUT fps
When the FPS button is pressed on the HOME screen and the sensor
frame rate is linked to the REC OUT frame rate, a message appears
instead of the list. While this setting is active, the sensor frame rate can
only be set by setting the REC OUT frame rate.
To link or unlink the sensor frame rate to the REC OUT frame rate:
1. Press the MENU button.
2. On the Recording menu, use the jogwheel to select REC OUT.
