For this shot Ashley wanted to keep Kiel's and Celu's reflections over 50 Cent so she used a rotoshape twice. One to black out the window so that 50 Cent could come through and one to keep the window. She made sure it was faded enough to get rid of the back wall in the booth. Ashley darkened and desaturated the 50 Cent clip to match it to the sound booth and added a glass texture over it.
Ashley also added film grain. Like the moving Sound Booth clip, this segment looked fine rendered out in Shake, but once it was brought in to Final Cut, the artifacts on the 50 Cent clip showed up.
