So testing more with prores_ks I can get proper interlaced encoding.

There is still variation depending on how I do it that I can only see
with mediainfo.

Following the link above -

ffmpeg -f image2 -pattern_type glob -framerate 25 -i '02*.sgi' -flags 
+ilme+ildct -top 1 -c:v prores_ks  -profile:v hq top.mov

I get a different (according to mediainfo) file from doing -

ffmpeg -f image2 -pattern_type glob -framerate 25 -i '02*.sgi' -vf 
setfield=tff -flags +ilme+ildct  -c:v prores_ks  -profile:v hq set.mov

It seems the second version is "more correct" - this may be irrelevant
as the frames are flagged the same, but it seems the container isn't
and the only way I know to see that is with mediainfo.

Just to bug me there's another anomaly in that I asked for hq and got
444 (not 4444) - fair enough I didn't specify pix_fmt, but I thought hq 
was 422 and so does mediainfo.
