How to fix 2d sprites getting blurry when moving

I'm doing a 2D Platform game in Unity 5 and i configured everything correctly on the import settings for the spritesheets and in the game view when the characters are idling looks awesome but when i move a character it gets blurry.

I have already tried lowering the framerate, but it didn't make any difference. I downloaded a spritesheet from internet (this one : http://i168.photobucket.com/albums/u190/dimension_w/GB-Mega-Man-Project/MegaMania_MegaManPlayer.png) and it gets blurry also.

Here i leave some evidence:

1. Only My Character https://www.youtube.com/watch?v=VCGpm7em2sE

2. My Character and Megaman https://www.youtube.com/watch?v=iSn61vTGbys

3. My character and import settings configuration for it https://www.youtube.com/watch?v=srl7lzICX0g&list=PLT1un-QEvWFrXLjX7AyFeFkcsaeBnsBRn∈dex=1

Please i need to fix this and i have been trying for two weeks.
