           Summary: transforming interlaced video (rotation), rotates also
                    the field
           Product: kdenlive
           Version: 18.12.2
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED

  Target Milestone: ---

SUMMARY


STEPS TO REPRODUCE
1. make an interlaced project (in my case pal HDV 1440x1080i)
2. load some kind of interlaced footage
3. appy a transform filter and rotate of some degree (6 for example)

OBSERVED RESULT
output image (also in the preview) has artifacts generated by rotated fields.

EXPECTED RESULT
plug in have to calc the "new" pixel after blending the fields, rotate it, and
place it on the new frame. After the entire image is generated, make the 2
fields.
input filed lines and output field lines have to be always horizontal, also if
i rotate the input "frame" ;-)
