Not all renders are created equally. Some Renders need to be cleaned up because errors, mistakes, or artifacts occur in the final 3d render. Fear not, we can fix those.

Who was it, that coined the outrageous phrase “fix it in post”.
Today we might just do that. Long live post-production software like After Effects, if the pressure of deadlines gets too high, we cannot go back and re-render in Blender, 3D rendering takes too long, per usual.
