    Hello,

    I have a problem with the quality of the video recorder.

    I am on windows 11 with nvidia 3070Ti

    Unity 2022,3,10f1 - 3D project

    I use open brush package :

    https://github.com/icosa-foundation/open-brush-toolkit/releases

    I choose on the graphics settings in windows the best



    Models comes from Sketcfab and from Open Brush, I also use particle system and fog

    I can’t use URP or HDRP because of the Open Brush package

    Video recorder package is updated to 4.0.2

    I record in 4k 60 fps

    same bad quality with 4k 30 fps

    I tried Unity encoder and Prores

    h264 and vp8



    I watch the game window and the video is clean

    but when I watch the result of the recoder the video is bad


    Please can anyone can tell me how to procede to have the good quality in video recordings ?

    Thank you !

    Hi, you can try outputting image sequence (in PNG format) and encode it in other video editing software.

    Hello 1,
    I have tried what you suggest to me, with After effects but I have the same problem, the image is not perfect, I have adjusted bitrate for 4k 60 fps, the fog is not clean.
    I have also tried to capture the game screen with OBS, I have the same bad feeling about the fog

    I think the PNG output should give you game view results. You can try changing the source to texture sampling (rendering at higher resolution & super sampling) and see if this reduces color banding in fog.

    When I export PNG from Unity I have this:

    The best I can have is to export jpg sequence from texture sampling and import it in Hitfilm. But it's not great
    There is no difference with an export in .avi uncompressed or in h264.
    I don't understand bitrate is really heavy in .avi and very lower in h264 but the quality is the same. May be the problem comes from elsewhere

    I am sad because I see the good quality in Unity but I can have it in my video.

    JPG should be fine and I remember that there's a JPG quality slider in Recorder 4.0.

    Not an expert in video editing, but you can find some online tutorials on rendering (Image Sequences -> Videos) high quality videos, like adjusting the video encoding settings.

    Yes I have searched, the best way is exporting uncompressed .avi, 10 secondes weight is 60Go and the quality is the same as h264, that's why I suppose the problem elsewhere
