Hi again, Just to follow up:

I'll let you know how I get on :-) This is super hackish: - it involves having a named pipe ending in .nut - it involves setting the video codec to huffyuv, as rawvideo causes melt to segfault - there is a weird field-order issue that seems to require an explicit bottom-field-first argument - in contrast to yadif, bwdif seems to actually need the deint option set to "all", despite it claiming this is the default but it seems to do the trick for me: Session A: % mkfifo fifo.nut % melt -profile atsc_1080i_50 -verbose title-audio.mov 15sec.mov -mix 25 -mixer luma -mixer mix:-1 -consumer avformat:fifo.nut progressive=0 field_order=tt vcodec=huffyuv acodec=pcm_s16le Session B: % ffmpeg -i fifo.nut -vf bwdif=1:1:0 deinterlaced-bwdif.mp4 Source and target files available here for those interested: https://home.nuug.no/~daven/20170407-melt/title-audio.mov https://home.nuug.no/~daven/20170407-melt/15sec.mov https://home.nuug.no/~daven/20170407-melt/deinterlaced-bwdif.mp4 >From what I can see, Brian's suggestion of using bwdif looks really good - I'm pleased to see the improvement in picture quality here!
