Please add filter visualization and command line operations, such as - filter_ complex "[0:0]bwdif=1[out0]" .

Add x264, x265 parameters, custom parameters and command line parameters, such as - x265 params: 0 "no open GOP = 1: bframes = 8"

Finally, add ass subtitle recording function

Hello!
Could you write the command - filter_ complex "[0:0]bwdif=1[out0]" more precisely? because ffmpeg gives me an error when I try to run with these parameters.
So I understand that this is deinterlacing, but the "out0" command should not be there, as it seems to me.
