I have some V210 files and in both .mov and .mxf wrapper do not seem to
have any interlace flag settings, although I know them to be -tff.
I wish to convert them to dvvideo, however the fieldorder=bff filter
only works if the source material is flagged as tff, which it is not.
I have tried various things, including using fieldorder=tff,
fieldorder=bff so that the first filter does nothing but sets the flag,
so that the second filter does what is required, but this failed.
I have also tried using -top before the input file, but this too did
nothing, as did using a scale filter with scale=iw:ih:1.
Does anybody have an idea how to force tff interlace handling?
