I am using Adobe Premiere Pro CC to edit a blue screen clip, however, once I apply the Ultra key to the clip, I notice that when I start to render (using Adobe Media Encorder CC), the top part of the green screen clip gets blocked (cut off) by the replacement background! I have tried different backgrounds but I keep getting the same chest-to-head level blocked off with the background. When I remove the Ultra Key and render the
clip with it's green screen, then it renders just fine! BELOW IS A SCREEN SHOT OF MY PROBLEM.
Today 2014.2 was released. Might want ot update.
