CATEGORY - TELEVISION... I am building a video mixing console for remote, 2 camera video recording jobs, using a Panasonic WJ-5500B SEG. When I plug in composite video from a camcorder (video out)... the output of the SEG produces constant rolling on the monitor screen.. . Do you think that I need a sync generator?. or would you conclude that the SEG is faulty?. Thank you, Terry Slater.
