We are scheduled to produce a webcast using a Panasonic HMX100 switcher. I need to insert a small company logo as a bug in the corner of the screen to remain permanently during the program. I had hoped to do it as a downstream key, so that I could still fade in lower third name IDs as a second key (that will be a luma key). How do I set this up so that the bug remains in the corner? I'm pretty sure that the switcher is capable of the simultaneous keys, but the Panasonic manuals are somewhat vague and confusing. Any help that anyone could offer would be most appreciated.
