I completed a title sequence last week. The base footage was shot on PAL DV, the final application was UK broadcast - via DigiBeta.
My fcp project was set to lower field dominance, everything slotted together well and I exported a quicktime onto a harddrive to be put to tape at a facility house.
They used AVID to play out the quicktime to tape. The field order on the finished work was correct (ie pans and other movement were fine) however there were 'jaggies' on still detail. We corrected this in an editbox by deinterlacing, disentangling, shifting field 2 down by two video lines, then bolting everything back together.
What went wrong?
