Unable to change shutter speed on micro studio cinema 4k

Hi,
so pretty much everything is in the title, I've been able to change every parameter I could, but Shutter speed just won't do anything, I've checked and double checked the documentation.
Code: Select all
#include <BMDSDIControl.h>                                // need to include the library
#include <wire.h>


const int                shieldAddress = 0x6E;
BMD_SDICameraControl_I2C sdiCameraControl(shieldAddress);
int32_t value = 500 ;


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  sdiCameraControl.begin();
  sdiCameraControl.setOverride(true);

  sdiCameraControl.writeCommandInt32(
    4,            //camera number
    1,            //command group
    12,           //parameter number
    0,            //operation
    value           //value
  );

  sdiCameraControl.writeCommandInt8(
    4,            //camera number
    1,            //command group
    1,           //parameter number
    0,            //operation
    8           //value
  );
}

void loop() {
  // put your main code here, to run repeatedly:

}


I've put a gain change to test the communication and it works.
Is the shutter feature not available on micro studio cinema camera ? Would be weird considering the parameter is accessible in the menu.
Or am I doing something wrong ?
