@kawax13, is it happening to all resolutions/modes? Do you also notice this even without the SD card (camera's preview)?
In addition to this, fluorescent or artificial lights (60hz in the U.S., 50hz elsewhere) can cause flickering. This means that you may have to adjust your settings for the environment/light you are shooting in. Try toggling the FPS, ISO and shutter speed to see if that will make any difference.
