I set the filters to 1 all, but the video after bluring seems high contrast

I tried reinstralling, updating Nvidia driver, asking some friends that use tekno's blur and using friend’s settings How ever i couldnt solve the issue at all

Try some different combination of color range and color space in OBS' advanced settings

There is nothing wrong with the recordings taken with Obs itself, but do I still need to try?

I can look into this more if anyone's willing to upload a sample clip to something like https://litterbox.catbox.moe/

After getting the clip I believe it's a color range issue. 'Full' color range clips become more saturated after being blurred due to being implicitly converted to 'Limited' by ffmpeg as it doesn't know that it's 'Full', since vspipe strips that info out (I think that's what's happening anyway - not an expert on this).

To fix it, add -vf scale=in_range=full:out_range=limited to your custom ffmpeg filters. This will convert your clip to limited color range properly, resulting in a properly saturated output.

For a full set of filters, I recommend: Nvidia GPU rendering: -c:v h264_nvenc -rc constqp -preset p7 -qp 14 -c:a copy -vf scale=in_range=full:out_range=limited CPU rendering: -c:v libx264 -rc constqp -preset fast -qp 14 -c:a copy -vf scale=in_range=full:out_range=limited

This fixes the issue for me using the clip provided by Tewxx, but let me know if you're still having problems and I'll keep looking into it.

Confirmed that the filter solved it for Tewxx, anyone else having this issue please let me know if that fix solves the issue
