Never have seen this before. Doing a simple animation in 3D Max 2021 using vRay 5 renderer. I can give more setting information if needed but thought this might be a simple setting that I am missing. See attached image. Why would a rendered animation (AVI) be exported as 2 side by side videos within one screen/view? Render output size is 1920 x 1080 (HDTV).
I just noticed that at the top left of the Vray frame buffer window it says "100% of 960 x 540".
