I am having the same issue. I record writing on screen and cut the videos into short educational pieces. We often use freeze frames between moments of writing on screen. We record the output of the computer as prores 442 1920x1080i with AJA Kipro Rack. I am editing the files natively in Premiere Pro CC and I am using Frame Hold frequently. The issue is visible in the program window and in a masterfile export. At worst the writing looks jaggedy, and so far it looks best when using flicker removal on the clip, but the resolution is obviously lower than the adjacent video clips.
Has anyone come up with a work around for this?
