There are two things:
a) The encoder needs to support interlaced encoding.
b) You need to tell it to do so using flags.
a) From what I found using Google and the source code, only the encoder
prores_ks does support it. See
and search for AV_CODEC_FLAG_INTERLACED_DCT in libavcodec/.
The encoder "prores" you use is "prores_aw".
b) The flags to add to the command line are "-flags +ildct", or even
"-flags +ilme+ildct". See also

We don't know what mediainfo is looking at here. I may be wrong and
mediainfo right. ;-)
