When I attempt to make my edited video into a movie choosing "all" as my choice for method of viewing, I get an error messsage as: "unable to build the render graph." If I choose "view on another PC" the render starts as I would expect it to, but about 30% to 40% into the render, it suddenly switches to the original unedited video and tries to render that. This would make an edited video (according to the rendering dialog box) that would be nearly two HOURS long. About 80% through everything stops.
I have no idea about the settings in the "make video" dialog box that could solve this problem.
