I am working with inverted masks on a number of clips, and I have a slight feather on the edges. It seems that some clips leave a ghost of the outline of the original clip (before cropping).
It seems to me that this is happening because the inverted mask is applied only just up to the edge of the clip and there is no bleed – so with edge feathering there is a faint outline.
A workaround I have been using is to then add another crop effect to each clip but this is getting tiring I have about 20 clips simultaneously in my sequence. Does anybody have any idea what else I can try?
