premiere doesnt “frame through” things properly, especially if you have interlaced footage or frame blending enabled. To know for sure you have to import your footage into vdub and frame through it and if its interlaced you’ll have to write a script (or use the deinterlace plugin) that drops the proper field to show you what exactly goes on.
Basically its this sort of thing you want a good tripod for and to know better what your camera is doing inside your footage. All this video engineering stuff is really a pain to deal with, BUT if you can figure out what each frame looks like independent of the other then you can figure out how to remove the ghosting, though this will cause a jump in your footage that you will have to go back through and frame interpolate inbetween the jump which will produce messy results in your case.
