[FFmpeg-user] bwdif filter question

[Mark Filipak (ffmpeg)]

Is the input to the bwdif filter fields or frames?

Since, according to previous threads, ffmpeg decoders solely produce frames, Based on this:
https://ffmpeg.org/ffprobe-all.html#bwdif
I honestly can't figure out which it is: fields or frames.

Thanks!

Note: I'm experimenting with virtual identities in my Thunderbird email client because the ffmpeg 
archives publish email addresses and I wish to spoof in order to avoid spamming harvesters. So, if 
this thread gets screwed up, kindly be tolerant. Thanks!
