I just happened to have this three-way video clip comparison done with MEP (MAGIX Movie Pro 17+ editor) to show how the native #11 video can be improved a bit with the free AviDemux editor, and much better with a commercial editor, such as MEP, using a vignetting correction mask filter to eradicate most of the corner and edge darkening and color shift. The background light level was problematic for the camera's auto-exposure metering in this particular video as you can see in the annoying "brightness hunting".
Another similar "free" method of vignetting correction using the VirtualDub editor is detailed here
