You're shooting in a dark indoor environment with low light and not using a custom settings. So you'll see both dark grainy photo's and blurry grainy video as a result.
Even on bright days, if I'm shooting indoors, I'll use a light attached to the Gimbal or selfie stick to get a better picture. This is probably why the forthcoming media mod actually has this as an option.
Also I've found that in indoor lighting, Superphoto works much better than HDR.
