Looking at the two pictures I think they are shot at different resolutions, different focus, and different amounts of light.
For example in the pic with the telecaster you can see the pattern in the knees of the person’s jeans, even the slot in the screws, the definition of the strings. it looks like the pic was taken with daylight illuminating the room. The pic with the red SG is in lower light, but also not in sharp focus, and it appears like a lower resolution. What are your video settings on your Vixia (fps and resolution). I am guessing the Vixia won’t let you set your aperture and shutter speed.
