I already searched the internet but could not find a solution to this. Maybe it is the same question as Why my animation render is getting greyish? but there was no answer.
I want to render a video with tracking, but the output "loses" color information and gets kind of greyish. I first thought that it is related to the renderer, but it happens in Cycles and Eevee. Therefore i made a sample image, added it to the image sequence editor and rendered it as 1 frame. Resulting in the same problem.
I placed the original image beside blenders output so that you can see the difference. The only idea I came up with is that something with the lighting is not correct but I can't find a setting for that.
I am using Blender 2.80 with the default settings. Only set the output resolution to match the input resolution.
