Comment (by jsevakis):

 Replying to [comment:5 kierank]:
 > Needs vf=scale:interl=1, I've already mention that interlaced files need
 interlaced upsampling but this was blocked by Michael.

 By jove, that did it! Much thanks!

 Here is the successful string:

 {{{ffmpeg -i /Volumes/GeneralData/FFXC_9014_3/BDMV/STREAM/00036.m2ts -vf
 scale=interl=1 -c:v prores -profile:v 3
 /Volumes/Media/MarmaladeBoyTest4.mov}}}


 So, here's the ultimate question: is this a bug and something that should
 be automatic when sensing an interlaced input clip, or just an omission in
 the manual?
