[FFmpeg-user] cropdetect and the round parameter

Does anyone know when using cropdetect and the round parameter is 16,
does cropdetect remove more or less to achieve a crop that is
divisible by 16?

That is, assuming the video's (actual) content dimensions are *not*
divisible by 16; will ffmpeg

A) show more black border


B) remove some of the content of the video

in order to obtain dimensions that are divisible by 16?

Thanks for any help!
