Depends what you mean by that, this command will create an
interlaced frame from 25 FPS footage but as they originate
from the same frame there is no temporal difference between
top and bottom fields.
It will not provide intra-field encoding. MPEG2 is to my
knowledge always frame base but capable to preserve
interlaced fields within the frame if flagged appropriate
