  • How to fix scrambled output

    26 janvier 2020, par Krishnakumar

  • How to use FFmpeg and GeForce Hardware to decode and encode 4K MKV movie to 1080p [closed]

    27 janvier 2023, par slyfox1186

    I am struggling with the instruction provided to convert a 4k Movie to 1080p so I can run it easier on my plex server.

    


    I have a Geforce 1080Ti and have enable cuda and all the necessary options when building ffmpeg.

    


    I keep getting a weird error and I am stuck at the below point.

    


    Here is my code that I am working on currently

    


    REM @ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
COLOR 0A
TITLE CONVERT 4K TO 1080P USING GEFORCE HW

PUSHD "%~dp0"

SET "FF=C:\MAB\local64\bin-video\ffmpeg.exe"

FOR /R %%G IN (*.mkv) DO (
    "%FF%" -hide_banner -hwaccel cuda -y -i "%%~dpnG.mkv" -c:v h264_nvenc -preset slow -pix_fmts yuv420p10le -vf scale='1920:-1' -c:a copy "%%~dpnG(1080p).mkv"
    )

ECHO.
PAUSE
EXIT



    


    below is the error output I get when running the above command
