Location Shooting Practise - GoPro

The GoPro was better quality than we expected, however isn't u to the standard we want for our video. However there are certain scenes in our music video (such as when our actress is driving) when using a GoPro would be ideal as we could attach it to the windscreen for some different types of shots. The issue with this is the difference in quality between the cameras and we are unsure of what it would look like if we swapped between cameras.
