Hello guys. So I have a glasses spy camera and sometimes I film with it and in the past the quality of the video was just perfect, everything was ok and just today something went wrong and my camera started to film with an extremely poor quality. So here is the part of the video itself:

Can someone tell is there something I can do, is there some video editing software that can help me to improve the quality of this video? If so, which software would be better to use? If it's not possible to do the perfect quality, maybe to improve just a bit? Please help. Thank you
