Video clip became blurry in Premiere Pro

[LHY]

Hi,

I have two video clips and they are both HD (they were both sharp), but all of a sudden, Clip 1 is now blurry. I don't know if I pressed the wrong button while editing, but the sequence setting looks correct. I've attached both clips. Can someone help?

I finally found where I made the mistake. While editing in Effects Control (Creative), I accidently reduced the 'Sharpen' without knowing.
