I always have the "show video in preview window" option turned on when rendering files so that I can visually see whereabouts in the video the rendering is currently at, but now when I render, all I see in the preview window is the frame that I'm currently at while editing.
This started happening in one of the later releases of Vegas Pro 20, but now I have just upgraded to Vegas Pro 21 and it's still happening.
I've ensured that I'm running the latest drivers for my NVidia graphics card, and my Windows 11 installation is fully up to date.
Is there any other setting I need to enable for this to happen?
Thank you
