Marcus suggested I try a vintage monitor and that did the trick. I suspect that modern composite interfaces have a higher input bandwidth than the vintage CRT monitors. I would think that some sort of filter would eliminate the higher frequencies that are causing the jitter, but was unsuccessful finding something.


I was hoping to verify that the video interface was working before purchasing (and paying freight) for a composite monitor. From what you are saying, a composite to HDMI converter would work well enough to do just that.
