Log and Capture the HDV native in a separate FCP project and software convert the files via compressor to DVCPRO 100. Then open your DVCPRO 100 project with the Varicam footage import the new files and edit away. You could toss the HDV footage but keep the FCP file encase you need to recapture the HDV original. Hope that helps. (the software conversion route retains image sharpness over the analog conversion route.)
I have multi screens at sigragh (SP?) but they use a laser grid the surface of a display to detect the location of the fingers not sensing technology under the display. In the video there is a OSX like dock on the top of that screen. But it is way cool. thanks for the post.
