S,M,L,and raw are all for pictures they refer to
S = small size
M = medium size
L = Large size
Raw = instead of like jpg, which does sharpen the picture in the camera. Raw processes the photo alot less in the camera and leaves it more like it was captured directly
Raw + L means it takes a large format jpg along with a raw copy as well
Hope this helps but none of those have anything to do with video.
