Not sure if this is the correct place for this post so forgive me if not.
Using a BM ATEM1. 4 Cameras (SDI).
Made a simple lower third graphic/TGA in PS. 3 layers. BG layer (black). Solid color rectangle layer over BG. Text layer over rectangle layer.
Alpha channel is present.
My issue is 2 fold.
Using the premultiplied option in the switcher I am getting a thin line of noise across the top of the graphic once its pulled into the media pool. Also the solid color is not solid, it has some transparency.
