Remove Mosaic

[App_rone]

Something else I've been wanting to do. I have a video with lots of mosaic, and I was wondering if I could use Avisynth to remove it.

The image of the video is here.

Does anyone have any suggestions?

Is this a joke?

Is this a joke?
Seems like a hentai anime mosaic removing request :D

Or. at least, is where "demosaicing" reached its highest point :rolleyes:

Look at this (http://www.extremetech.com/extreme/177435-depixelating-porn-is-it-really-possible-to-restore-8-bit-genitals-to-their-former-glory) snake oil.

Semi-serious mode: as in video mosaics there is always some moving or panning, probably at least a blurred image can be reconstructed. The point is if anybody has time (and material LOL) to get reasonable results.

Easy, use BlankClip()

Pls provide a video sample.

Horny man ahahaha

It looks to be 22x16.Resize down, resize back. That's all I got.

Here's the video I am trying to remove mosaic from.

1 step beyond MWilson's suggestion, but needs a little bit of tweaking for a perfect result.

EDIT: Moved AutoLevels to the end of script

Looks nuttin like a Nipponese prawn. :)

EDIT: Added jm_Fps() after seeing John viewing the thread he linked below
(Probably better result if following that below thread, this post script aint much better than the source).

EDIT:
this video is really awful.
Maybe so, but the tune is great.

One question. Could this be called Super Resolution :)

This does appear to be a joke. However, if the OP is serious, I did have to do something similar several years ago when I wanted to restore a 1991-era digital video that was only 160x120 at 12 fps. Here's the thread where I provided the original and, after a lot of help from people in this forum, I posted the result:

Ideas for restoring early generation (really old) video (https://forum.doom9.org/showthread.php?t=163014)

Some of the ideas people gave me might be helpful here, although this video is really awful.

Among others things, You'd need this filter (http://www.compression.ru/video/super_resolution/super_precision_en.html) but it's never been released publicly (shame on them ruskies)
