Hi I played PCSX2 for a long time,and in one day i decided to record a video with atube catcher recorder,so for some reason PCSX2 lose the high quality appearing Black lines on emulator screen and there was low brighteness,I did a video comparing Wii(Dolphin) and PS2(PCSX2) here: http://youtu.be/h7e2bBmFu78

How can I change this to normal?
