Gorge,

Well, there is "sparkill" in the forum who has worked out for himself the color equivalences between OBS and CinGG.

Hopefully, this is not an alternative name for you.  Please see this forum and see if that helps -- scroll down to: 21/06/2021 10:22 pm.

Hello all,

I'm truly loving cin/gg as I've switched to it as my primary editor.

I do have one slight problem, which I can work around.  But I'm wondering if I'm doing something wrong.

My output video's don't look *exactly* like my sources.  Even if I just drop in a video to CinGG and render

it, the output is NOT the same as the input.

I have to do these filters to get my output video kind of 'close' to that of my sources:

Brightness/contrast filter:

+.063 bright
+1.292 contrast
deselect boost luminance

My input video's are recordings from OBS.  I suppose I can just add more brightness & contrast 

inside of OBS and then they should come out of CinGG fine.  I'd like to avoid adding filters to the render chain

of cinGG to save me encoding time if I can.

I have also completely removed my ~/.bcast folder and recreated my setup so as to avoid any conflicts there.

Here is a 'mediainfo' output for a file that my OBS produces:

I'm using the latest CinGG app image on Ubuntu 21.04.  It works great BTW!

I am using RGBA-8 Bit for my cin-gg format.

I'm rendering from cingg to h264 as well.

I have the nvidia binary driver installed, version: 465.31

I also have the CudaSDK installed here as well.

The 'overlay' mode is 'normal' in CinGG for the video track

The 'fade' is at 100 in CinGG.

Thank you for all your hard work on CinGG !  I truly appreciate it!
