Need Some Help! Upper field dominance on progressive footage?

I am re-posting this because I am in a time crunch and need to try and find a solution...

 

 

 

I shot footage at 1080p, 30 fps. In my FCP sequence the clip properties say there is an upper field dominance...

 

Upon outputting my HD footage to SD DVD it looks rather crummy, and there is a green horizontal line on the top and bottom of the screen. Is this why?

 

Finally, what is the best, and fastest, way to correct this, if it is, indeed, the problem...

 

Thanks for your help...

    If it is progressive, the field dom setting is irrelevant.

    Because 1080 isn't a multiple of 480 (NTSC) or 576 (PAL) lines. You have a remnant of a line left over with incomplete information. What's the intended delivery method? You certainly won't see those lines on a TV set.

     

    If it's intended for viewing on the web, use the crop controls in Compressor.

    1080p is, by definition, progressive and therefore has no field dominance.

     

    IF, when you say "In my FCP sequence the clip properties say there is an upper field dominance" you mean the sequence settings, then that may account for the output.

     

    Duplicate the timeline (so if it doesn't work you still have somewhere to re-start), change the sequence setting to Field Dominance = None, mark in and out for a short sample and export. If the short sample is clean, than you know what to do. If not, post back.
