I recently downloaded a Japanese Adult Video (JAV) that had been "uncensored" by removing the Mosaic (MR).
Is there a free, simple to use, program that I could use to Remove the Mosaic of a censored JAV?
Doing a search I found VSDC Free Video Software that seemed that the only free thing was the download, it implied but never mentioned the amount of a monthly fee and it appeared to be extremely complicated, claiming it could do all kinds of things to improve your videos and didn't mention Mosaic Removal specifically.
I don't need to "do all kinds of things" to improve a censored JAV. I just want to Remove the Mosaic (MR) to make it uncensored.
Any recommendation would be appreciated

Hi, i think you can be interested with that:

Instead of using VirtualDub, use VirtualDub2 (http://virtualdub2.com/ or https://sourceforge.net/p/vdfiltermod/wiki/Home/)

After if you want to do a better work, and not lost the details of unmosaiced parts,
you can use with VirtualDub2 the filter "fflayer" which puts a video within a video, in your case put the enhanced video into the original mozaic video, and use "Blending" option on it to select the area at a start frame to an end frame. Repeat this for all the mozaic part, add a new filter "fflayer" change the blending area, start and end frames.
When you finish this, you can recompress your video.

Not easy? Yeah maybe but it's just a lot of work to do.

A second method more simple:
Use DeepMosaics https://github.com/HypoX64/DeepMosaics
but it needs a good computer.

I never test to remove mozaic, so good luck.

Thanks I prefer simple so I'll try to use DeepMosaics https://github.com/HypoX64/DeepMosaics
