Capture message delay

Hi, I have a PrintStringDuration=0.5 param set up in my defaultengine.ini to shorten the time log messages are displayed in run time. This works fine - and my ‘blue’ log message now only pop up briefly. However - I also have some ‘red’ ‘Start Capture’ messages coming up from a blue print I created >Activated when I press left dpad< - these messages don’t seem to be affected by the PrintStringDuration. Does anyone have any ideas how I might control these ‘red’ messages in a similar way? Since I can’t find the trigger I’m assuming that its something the engine throws out by default…

Is there an option somewhere to suppress these Start Capture messages? Please help urgently - I need to capture some footage with time stamps on and this is causing all sorts of problems…

Many thanks - A.
