Hi Liz,

Yes dealing with matte lines is the never ending task for compositors.

I see you're in 8 bit mode - 32 bit float might help here, but also are your bag and BG footage masks the exact same size? It might be better to overlap them by expanding one of them, and then feathering them both.

Although that effect you're using might only be 8 or 16 bit, working in 32 bit with color space set to linear makes these kinds of composites easier (usually). Use the dynamic range compounding preset around the effect if the effect is 8 bit.
