Lots of people don't realize that you can often get a better IVS image by going into Manual Mode ... have the Video Iris as wide open as possible ... and use the Up and Down arrows from the "menu" controls to set the IVS exposure. Sometimes one also needs to use the Video Iris in conjunction with the Manual arrows. You can get a brighter more colorful cleaner image ... often.
