No interlaced output in ffmpegX

[havema-1]

I can't seem to get interlaced PAL output from ffmpegX 0.0.6i.

Input: Full quality DV encoded PAL QT file exported from iMovie 2 with its High Quality flag set and saved in QT Player.

ffmpegX settings: SVCD (PAL) Quick Preset, mpeg2enc Deinterlace unchecked. I have tried all ffmpegX's Interlace options (Field, Frame, Not interlaced) but the output is always progressive (i.e. there are no comb lines on computer monitor). I can get good interlaced output via MediaPipe's ppmtoy4m -L -I b and mpeg2enc -I 1 settings.

Is there some ffmpegX option I'm missing?

What is the difference between ffmpegX's Field and Frame options? With the Field option there are similar colored artifacts I get via MediaPipe's mpeg2enc -I 2 although the output is progressive with ffmpegX.

The QT decode routines I'm currently using always pipe deinterlaced frames into the encoder.

Have you considered (or is it possible) to add interlacing to ffmpegX?

I have interlaced DV as an input and converting and watching it progressive on a TV makes me dizzy

It's in the big to-do list.
