I was working all day with Premiere Pro and After Effects linked on and I snet another video fron Premiere to After and when I tried to create a mask it selcted an area different like in the image. I checked everything on the mask panel and It was all nomal, please help.@
What are those footage files? What are your comp settings? Do you use specific effects on the layer? What else?
This usually happens because you have an effect on layer, that distorts the image. Some effects are applied after the masks like this. If you want the ability to use a mask ontop of the distortion, you could solve it be precomposing the layer.
