I tracked a scene, and then successfully set up a tracking scene. I then added my mesh to the scene, but now when I render the sequence I still get the Video I tracked as the Background.
Generally, to render an image without the background you need to, in the "Scene" tab unselect the "transparency" option in the Film section, and select RGBA image as the output of the render.
This didn't work for me for some reason, so in the Camera Settings I removed all Background images, which in my case were only the video clip. In my outliner window there was an "object" (not really an object, just dont know what you call individual thins in the outliner window) called background, which I first deselected for the render, and then after seeing no change deleted completely.
I tried restarting Blender to see if that would change anything, but nothing happened.
When I render an image in the rendered window I can see the optioin to view the fore and background, which I can view separately, but when animationg a sequence Blender automatically merges them and saves them as one image. I thought of disabling this, but I don't know how to do that.
Does anyone know what to do? Thanks
