Hi. For what exactly do you want interlaced format?

Is it to obey some specs like bluray specs which for some resolutions
and fps need the stream to be flagged as interlaced?
Than --fake-interlaced is ok. It will flag stream as interlaced but
all MBAFF encoded macroblocks will be progressive.

If you need to make content really interlaced than you will need
ffmpeg or something else to convert video before encoding.
