Trying to use a Background node in Fusion to make an image the same size as my Timeline. All is well except the Background node won't go fully transparent when pulling the Alpha slider down in the Inspector for the Background node. It goes partially transparent but not totally.
Ideas?

Could you post a screenshot of your node tree? What node are you viewing?

What color is the background? If it's not black, you will end up with a semi-transparant image, since the BG color isn't multiplied by its alpha.

... and if it's not black, you could add an Alpha Multiply node afterward to make it fully transparent.
