Not sure about the black line on the transition, I'd have to see it, and I don't think either of my software does it. Great idea though about zooming in between those bars, I never thought of that. I edited it in Pinnacle, which can't zoom, but Premiere 5 can. I only tend to use Premiere for 'tricky' bits like that, and I haven't delved very deeply yet into what it can do. I got in touch with my video club's expert and he told me how, and although I may not alter this clip - it's been 'finished' quite a while - I am doing something now where it could come in useful.
Win XP, Athlon 1.8, G force 3 T, 1 60gig drive + 1 250 gig, Pinnacle Studio 9 plus mostly, Premiere 6, and Vegas 5 sometimes, Soundforge, Cool Edit.
