  • How to (visually) losslessly compress a video with GPU acceleration in ffmpeg ?

    4 juin 2022, par Tizian Heckmann

    I am trying to compress a video in ffmpeg with GPU acceleration, but the result always looks bad. This is what I have tried and none of this has worked for me :

    &#xA;

    Preset 18 is called "best quality" when looking at ffmpeg -h encoder=hevc_nvenc
    &#xA;ffmpeg -i input.mp4 -c:v hevc_nvenc -preset 18 compressed.mp4

    &#xA;

    Also :
    &#xA;ffmpeg -i input.mp4 -c:v h264_nvenc -preset 18 compressed.mp4

    &#xA;

    Unfortunately, the preset lossless is deprecated. When trying
    &#xA;ffmpeg -i input.mp4 -c:v h264_nvenc -preset lossless compressed.mp4
    &#xA;the output file just grows enormous.

    &#xA;

    Any help is appreciated.
    &#xA;Edit : Since my question is being received as inappropriate by the community, I would like to know why. This was my first question, any advice on how to word it better or tell me why it just does not fit here would be appreciated. Thank you.

  • How to bold a font in ffmpeg ?

    28 février 2023, par Peter.k

    I have an issue which I don't fully understand. I use font to merge subtitles in video which is installed in my laptop and everything works fine with this code :

    &#xA;

    -vf "subtitles=tt101.srt:force_style=&#x27;FontName=Lucida Console,Style=Bold,FontSize=15,PrimaryColour=&amp;H00111188,OutlineColour=&amp;HFFFFFFFF,BorderStyle=4,BackColour=&amp;H44FFFFFF,Outline=5,Shadow=0,MarginV=10&#x27;"&#xA;

    &#xA;

    But later I found this font isn't really bold but regular. I checked in my system and indeed, there's no bold version installed, so this Style=Bold fragment is ignored (as I think it is). But how the hell, while using this very font in some other programs like Word, Excel, Photoshop, PotPlayer, etc, I am able to bold this font anyway ? Why ffmpeg doesn't make it ? Does these programs use something else than Windows show in the Font catalog ?

    &#xA;
