So basically a pic became my background composition and i'm not able to remove it. I only have that when I put the composition 1080x1080 and it's not really a background because when I add a clip and I scale reducing it I see a black background, not that frame. I started a lot of new compositions but nothing happens..the frame (the pic) is still there!
Look, the pic is still there and I don't have the pic where I edit.
This is hard to explain so i'm sorry if you don't understand, i don't know what is going on.
