Motion tracked Video doesn't show up in the render or in the compositing tab I tried to add a 3D object to a clip by following a youtube video. But clip doesn't show up in the render or in the compositing tab. It show up even in the camera view. I didn't change any settings.
please help.
Thank you.



And the  rendered images has only the cube in it like in the picture above.
What you are missing is the alpha channel on the render layers. Without an alpha channel the &quot;alpha over&quot; will fail. Enable Film&gt;Transparent so that the areas with no geometry will be &quot;transparent&quot;.
