Hi,
Can anyone explain this effect for me?
I've just opened a new (empty) project in UVS 9.0, gone to "Create Disc", and added an mpeg file. The mpeg file is lower field first, DVD 4:3. In viewing the scene changes frame-by-frame, I notice that the image between two adjacent scenes shows one scene overlayed by the other. Is this normal, or is it perhaps showing the upper field from the previous scene and the lower field from the subsequent one? It's not evident when viewing the clip frame by frame in the "edit" timeline.
Thanks,
Steve.

Can we assume that the mpeg you used was an already rendered one and made up from amalgamating two or more earlier video clips? I ask because I have certainly seen this same thing in such circumstances, and particularly where there was a transition added -- the ghost scene seemed to show up more clearly against a transition. In fact it was my one real gripe about VS9, and drove me first to use MSP Pro more regularly, and more recently to acquire Adobe Premiere Pro 2.
However, I think your own explanation seems to be fairly accurate. But in my case, it seemed to be related to using the 'virtual' clips made when you cut an original video into several clips on the timeline. You can otherwise treat these new clips as separate files, move them around, edit etc, though in fact they remain part of the original clip. In my case, it seems that the very fleeting but annoying ghost image was from the previous scene to where the clip had originally been placed in the overall video, and it seemed as though VS9 was dragging a frame or part frame/field from that earlier scene to where I was placing the virtual clip. My only work-around was to make actual new files (Save Trimmed Video) when I broke up an original video into several clips, instead of virtual clips. Then I would check the new files frame by frame, and usually, where I could, chop off a frame or two at the beginning and end and save trimmed video once again just to be sure since, as you say, the ghosting effect was not really detectable in the timeline. A bit klutzy perhaps, but it seemed to work.

In this case, the mpeg was the orginal download. The "Create" and "Modified" dates are the same.
