I made a rather simple animation using video sequence editor (mostly blinking between two images), but for some reason I cannot render it. When I clicked render animation, all I see in the render result window is the blank "image" and nothing happens. I made the animation in blender 2.8 and I though maybe there is a problem in blender 2.8, but it didn't work (the same file) in blender 2.79 either. This was the second try of the same animation, first rendered fine, but crashed so I had to start over. This is what I get: I can render image and get the first image of the video.
