    I’m doing a screen replacement in a static shot by simply superimposing (on a higher layer) a JPEG of the screen I want over the screen in the shot. In the attached screencap, the upper photo shows what I see while positioning the JPEG. The lower photo shows what’s displayed during playback. The problem is those black artifacts across the white lines, kind of moireish. What’s more, I’ll get the artifacts if I scrub through the clip a frame at a time, but they’ll disappear if I stop on a frame for more than a couple of seconds. Any ideas about what’s causing them and how to eliminate them greatly appreciated.

    In your program monitor are you set to full resolution in playback?

    There is a setting for playback and another for still.

    It’s the wrench icon.

    Did you find the solution?

    Right now i am editing football footage that is 29.98 upper field.

    When i step forward or backward in source the i see the individual fields, then when i stop 2 seconds later the 2 fields resolve and i get a normal image.

    This sounds sort of like what you are experiencing.

    I haven’t solved it, but it doesn’t happen in the exported video, so that’s they key thing. The Display First/Second/Both Fields options are grayed out for me, maybe because this project is 1080p?
