Sample video file. It seems it should be easy but I'm having a hard time figuring out how to do it. Thanks in advance for helping !

    


  • FFMPEG CROP BLACK BARS BAD QUALITY

    9 janvier 2020, par Gustavo Gonzalez

    Hello im using this command to remove the black bars and make the video fullscreen ,

    ffmpeg -i 1.mkv -vf "crop=1920:800:0:140,scale=1920:1080,setsar=1" -c:v h264_nvenc -rc:v vbr_hq -cq:v 0 -b:v 27000k -maxrate:v 26000k -profile:v high -preset slow og1.mkv

    It works good ,
    But the problem is the quality of the video, there is a lot of difference between the original and the new,and apart from that it’s like the video is a bit stretched because of the new crop settings.
