                  @najlou One simple way to do it is: create two images and toggle them in a qlabel with timer.

                              @najlou This does not really help, as it does not show how the widgets are positioned (or put in layouts)...

                                  @najlou said in picture with a blinking effect:

                                  i placed the label in the scrollarea

                                  But how exactly? Is it over camera view? You need to really make it clear how everything is arranged exactly, else how should anybody know why the label disappears when you start to play video?
