Which method of deinterlacing in APP 1.5?

[Mike Velte]

from the Help files;

Always Deinterlace
Converts interlaced fields into whole progressive-scan frames. Adobe Premiere Pro deinterlaces by discarding one field and interpolating a new field based on the lines of the remaining field. It keeps the field specified in the Field Settings option in the Project Settings (see Specifying project settings). If you specified No Fields, Adobe Premiere Pro keeps the upper field unless you selected Reverse Field Dominance, in which case it keeps the lower field. This option is useful when freezing a frame in the clip.

Thank you. Obviously, that means the method => skip fields with interpolation…
