my background movie-clip final render appears flipped. I have checked whether the camera is mirrored or in the background image options if the 'flip horizon' is checked - I've tried to render with the 'vertical flip' option checked but still the final result is the same, a horizon flipped. The video appears on the correct horizon on the 3d viewer, even on the render result preview. When i choose render active scene, blender renders out the background video flipped.
Please, some one help me out, thank you.
