When I animate with Frame by Frame using my QC5000. I always see bars going up and down the screen but when I changed the light it wasn't as bad but it's still there. I haven't released a film using frame by frame yet incase people said things about it. I have 2 QC5000 and use one on a Mac in my Dad's house and another on Windows in my Mam's . there isn't a problem in my mam's, Just in my Dad's. I need help
