I have been editing and rendering video every week for several months and just this morning when i rendered a video it added a blue hue to the render. I do not see the hue in my timeline or preview window but it shows up during the render and in the final product (after render). I also have a static graphic at the front end of the video that has a blue sky background but the preview window shows it as orange-yellow. In the timeline it shows correctly and in the rendered product it shows correctly.

Using Vegas Pro 19 build 651. Hardware set up has not changed for months and have not had this problem until this morning.
