Comment:

 That's becouse there is no console output since I'm triying to Redirect
 the output but I only get an empty file as as an output. Sorry for using
 the wrong formating and making it look like there was a console output.
 This is the old build a I was using that did NOT have the problem (it's no
 longer online outside of web archive) with this build I can redirect the
 output to a file (the output in the file is just the error Message for not
 specifiying any input):
 https://web.archive.org/web/20190426212558/https://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-4.1.3-win64-shared.zip
 This is called version 4.1.3 don't know if has another name or something
 but clearly there is a version 4.1.3
 Both the latest realease build from gyan.dev (4.3.1) and latest dev build
 from BtBn (ffmpeg-N-99959) do have the issue with them it just creates an
 empty file with no output whatsoever when trying to redirect output in
 powershell.
 I hope this is enough information do I need to try every version to find
 out which version this firt happend in or build it myself or something?
