I'm editing using FCP and After Effects. I'll output to a Sony PDW-F75 deck through the IOHD using the HD-SDI out. I'm working in ProRes 1080i. Most of the time, I can play out of FCP and record on the deck. Sometimes, however, the video will jump horizontally during playback. It plays fine inside of FCP and looks okay while playing back. However, on my HDMI monitor and on the F75 deck which are fed by the IOHD, you can see the video jump in a quick flash. It seems to only happen with graphics. Does anyone know what might be causing this? Thanks.
