FFMPEG Not Flagging Interlaced Video Properly

[ENunn]

I'm trying to encode one of my VHS captures so I can put it on a DVD. Usually what I'd do is run an AviSynth script through FFmpeg with the following code

-c:v mpeg2video -vf setdar=4/3 -b:v 9000k -target ntsc-dvd -c:a ac3 -top 1 -flags +ilme+ildct

Usually "-top 1 -flags +ilme+ildct" sets the video to be interlaced/MBAFF top field first, and it's been working very well for me for a long time. However, it's not wanting to work properly now. It's jumpy and I don't know what the fix is. Example attached.

I tried top 1, 0 and -1, all have the same result. When I'm encoding to x264 I tried both -x264ops tff=1 and bff=1, same result. I have another file attached that was encoded a while back, same flag settings although it's encoded with x264 instead of MPEG-2.

Does anyone know how to fix this? I'm running the latest BtbN FFMpeg. ffmpeg-N-100688-ga423bc9dc2. I tried the latest cyandev version as well, same result.

Maybe:
-c:v mpeg2video -deinterlace -filter:v yadif -b:v 9000k -target ntsc-dvd -c:a ac3 -top 1 -flags +ilme+ildct

-vf setfield=tff

You can add it on to the filter chain
eg.

-vf setdar=4/3,setfield=tff

Maybe:
-c:v mpeg2video -deinterlace -filter:v yadif -b:v 9000k -target ntsc-dvd -c:a ac3 -top 1 -flags +ilme+ildct

Doesn't play back at 60fps. Probably need to change a yadif setting. However, I'd prefer to not deinterlace then reinterlace.

-vf setfield=tff

You can add it on to the filter chain
eg.

-vf setdar=4/3,setfield=tff

There we go! This works! Thanks!
