I'm trying to figure out how to use yadif / yadif-2x with ffmpeg to convert 50i source material into 50p output that preserves the motion of all fifty fields per second. Right now, I am using the following command, which creates a frame-doubled version, essentially the same as 25p output.

ffmpeg -i input.m2t -f:v yadif=1 -c:v prores output.mov
Using yadif=0 makes a deinterlaced 25p file. Using yadif=1 makes a deinterlaced 50p file with doubled 25p frames. I need to make a deinterlaced file with 50 unique frames per second, and I'm pretty well certain this is possible. Is that what yadif(2x) is supposed to do?
