I tried that but had no joy. I added a step and am now a happy camper.
I clicked on "Output Modules" and set that
to use OpenGL video output. Previously, even after using your setting, it was set to "Default".
I left enabled what you had specified to set.
But you still get the credit for this, you put me on the right track.
Thank you, the pixelation and edge aliasing are now gone in two files I used to test this.
