Re: TC accurate edits during conversions

I had this exact thing happen to me last week during output. I was working at 1080i and about to edit to tape when the ESPN executive asked me if we could do 720p instead. I said 'sure' and set it up in the Kona Control panel, leaving all the other controls in FCP at 1080i 29.97 as usual. So I did the output and everything went well, then as I was checking the tape, I immediately noticed that it was off by 1 field. This never happens during a downconvert to NTSC or a straight layoff to HDCAM. It was only in this case when I was converting 1080i to 720p on a 1400 DVCPro HD deck. Very strange. I couldn't sort it out and she was fine with it, as they were going to assemble the show in Bristol. But I found it very strange that it was happening in the first place.
Thanks,
