hey there,
back then it was possible to just directly move an interlaced mpeg2 file into a ffmpeg cmd for deinterlacing.
and it just came out fine as fully deinterlaced progressive video.
However in some of the rescent versions they changed that and now and doesnt deinterlace at all and just comes out as interlaced. mpc shows:
Scan type : Interlaced
Original scan type : Progressive
Scan type, store method : Interleaved fields
Scan order : Top Field First
back the in the old version simple
would be recognised asCode:"%FFMPEG%" -i %INPUTFILE% -c:v mpeg2video -qscale:v 6 -vf "bwdif=mode=0:parity=0,fps=25000/1000" -aspect 4/3 -f MOV %1%.mov"
Input #0, mpeg, from '...........':
Duration: 01:22:36.48, start: 0.170567, bitrate: 14521 kb/s
Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn
and output
Output #0, mov, to '...............':
Metadata:
encoder : Lavf59.27.100
Stream #0:0: Video: mpeg2video (Main) (m2v1 / 0x3176326D), yuv420p(tv, bt470bg, progressive), 720x576 [SAR 16:15 DAR 4:3], q=2-31, 200 kb/s, 25 fps, 12800 tbn
but with rescent updates theese days it's
Output #0, mov, to '..................':
Metadata:
encoder : Lavf59.27.100
Stream #0:0: Video: mpeg2video (Main) (m2v1 / 0x3176326D), yuv420p(tv, bt470bg, top coded first (swapped)), 720x576 [SAR 16:15 DAR 4:3], q=2-31, 200 kb/s, 25 fps, 12800 tbn
I tried using -top , -field_order progressive as additional commands but that doesnt help either. The only way the output was recognised right would be to index it with dgindex and letting it run as a AVS script and sometimes even that only works if you use the "proclearall()" command in the end even when using an avs deinterlacer instead of a ffmpeg one.
Maybe someone knows a solution for this. Thanks.

try this:
Code:"%FFMPEG%" -i %INPUTFILE% -c:v mpeg2video -qscale:v 6 -field_order 1 -vf "bwdif=mode=0:parity=0,fps=25000/1000" -aspect 4/3 -f MOV %1%.mov"

thanks pandy but it sadly won't work . if ffmpeg keeps on changing for all kinds of weird stuff I should consider switching back to an older version. I'm also getting theese annoying packed size too small errors which never where there in the older versions and I personally dont need all the UHD and what not fancy stuff anyways.

I downloaded 5.1.2, Windows 64 bit, from here:

Using your command line on an interlaced MPEG 2 video resulted in a deinterlaced video, encoded progressive. Exactly as expected.
Maybe there's something wrong with your source? Upload a sample.
