How to remove pixellation from video?
|
There are different types of video that people called pixellated. Often
they use this word for video whith blocking artefacts caused by strong
compression. This is an example of video with hard blockiness:
In such video we can clearly see squares (blocks) but these squares are not all solid,
they have some details within. A real pixellation is different. In case of
real pixellation, the image (or its part) consists of solid squares, where
all pixels within one square have the same colour. Here's an example of
pixellated video:
Same effect is also called mosaic. If you have this type of video, read
how to remove mosaic.
And if your case looks like the first example above, then what you really
need is deblocking. This process will smooth edges between blocks while
keeping details within blocks. There's nothing to do for super-resolution,
it doesn't really work on strongly compressed video (see
when super resolution doesn't
work). There are two filters for getting rid of blocking artefacts that you
can use in Video Enhancer:
MSU Deblocking and
MSU Smart Deblocking. The latter is included in
VirtualDub Filter Pack. Just open your video
in Video Enhancer, switch to Advanced mode, select one of these filters,
select output compression and press Start. After deblocking you'll have
something like this:
