doesn't work

[shafschwd]

1.i am running windows 1809

2.i am using .exe

3.i am trying to hardsub some vids here is the command
ffmpeg64 -i "%~1" -vf scale=1920:1080,format=yuv420p,subtitles="%~n1.mkv" -acodec copy -profile:v main -level 4.0 -preset medium -crf 18 "%~dnp1.mkv"

the thing its not showing anything so i can't give u a output what i mean by that is its not showing up on context menu
even if i do it file explore export way after saving no registry file generate
and if ur wondering why is it that i am calling ffmppeg as ffmpeg64 its beacause 2 ffmpeg on my pc
one is 32 and other one is 64
