Almost good. I love that it sharpens videos but it is laden with bugs and it is glitchy. it's unfortunate no video player in android 8.1.0 has sharpness adjustment option. I just don't know what to do other than pray that the maker of this app improves on it.

(1.3) GOOD = It CAN "sharpen" a video. *It can play SOME videos at full screen size. *You can "sharpen" a video (& watch it) WITHOUT saving it. (You CAN save the result if you WANT to). BAD = It does not say HOW it "sharpens" a video (read = Lanczos, Unsharp mask, increase contrast, change gamma, AI, other). *HUGE interface (so it can't play SOME videos at FULL screen size.) *No way to change the (displayed) aspect ratio. (Needed for videos with WRONG aspect ratio.)

Exported video is the same as the original.

Junk

Bad app
