Mosaic, but not because its adult material..

I have Premier Elements 12, which I bought years ago, but just recently started actually playing with.  I have a video that is pretty faded and poor looking.  When you frame by frame it, you can see that lots of the resolution has been lost, and the image has lots and lots of varied squares of uneven color and exposure.  I realize I can't get resolution back.  But I am hoping there is some way to to flatten out the exposure/colors so that its more like a frame, instead of a quilt.  If this was just a photo, I'd be happy to play around with it and see what I can do on my own.  But this is a 20 minute video.  And I don't have the time/patience to go frame by frame and correct it.

Well, any of the Adjustments may be helpful. You can also try the Sharpen effect (under Blur & Sharpen).

But as you know, there is only so much you can do.

I now have the trial version of Adobe Premier CC Pro 2018 for a few days.  Heck of a learning curve to adjust to after the learning curve of geting use to Premiere Elements.  Although, lots of ways to do stuff that is so much easier and smoother.    That having been said, any idea if there is a way to to smooth out the colors so that they are even, instead of a quilted mess of varying brightnesses, contrasts, off colors, and exposures?    Imagine a scene with a sky in it, and at least 90 per cent of the sky should be the same color blue.  but one row of the sky is like 20 different shades of blue squares.

If you have so called squares in the image it is just bad footage, bad compression.

There is a saying: garbage in, garbage out.

Dont expect much or rather anything.
