First a 4 point garbage matte was added on one clip to act as a crop over the other full clip.
This created a noticeable line down the middle of the screen.

A mask feather was then added to soften the edge of the clip; removing the split screen line down the middle.

A colour corrector was finally added to adjust the white balance to remove any sign of split screen.
This is the final draft of the confrontation!
