I use source interlaced video with fields (1080i/25, UFF, MXF OP1a or DNxHD format) in project. When I render output video with UFF (same interlace), fields in video are reversed. But fields from animation in AE (motion, rotation,...) ar OK. It is not problem in iterpretation of source video, all setings look OK.
This problem is only in AE ver. 2017. When i open same project in AE 2015.2, fields order is OK.
I try change field order in Interpret footage:
Separate fields set to LFF - render fields reversed
Separate fields set to off - reder is OK (fields in right order), but problems with masks and etc.
