Hi,
I don't want this mark made by a mask, how can I remove it please ?
you are not seeing the mask overlay, but the result matte composite out of combination of the effect and the mask. the mask render first, then effects - causing this outline. you should work your way around the problem like setting the mask in a different layer and use it as an alpha matte. alpha matte will render last so effects, then masks...

Click on the Show Mask button in the bottom of the composition panel (the button in blue)

Thank you for the answer, I found a "toggle mask and shape path visibility" it was enabled in blue, I clicked on it but you can still see the trace of the mask...

I am not sure this is a layer mask. where are the vertices? press UU on your layer and show us the full interface one more time.

you need to create you matte in a different way. There is another approach than the one I mentioned that is easier - Try this:
Twirl down the difference matte effect in the timeline panel and you will see a Plus sign in the compositing options. Click on the plus sign. Now the effect will be restricted to the mask but in a different manner That won't introduce the edge.

yes I see now the second approach won't do. the effect is only applied on the mask section but the layer is rendered as well. so the first approach works. Great
