Layer panel hides my footage when I toggle paint on transparent
Hello, I am attempting to do the scribble light effect in AE but when I access the layer panel and toggle ON Paint on Transparent it hides my background footage and goes black. I can still paint but I only see the brush strokes. I can see the footage again when I set the view to none, but as soon as I make a brushstroke it goes back to paint and my footage turns black again. I am a beginner so its probably a simple issue, but I cannot find a fix for it anywhere.
