Video Enhancement Software

[lazyturbo]

Does anyone know where I can Download or Trial some Video Enhancement Software. Is there such thing available on the consumer market? You always see cops use it in movies to enhance security camera feeds, etc.

I just want enhance some of my blurry videos. You can sharpen pictures using Photoshop, so I'm guessing there should be something similar for video?

Thanks.

avisynth together with some sharpen filter, http://www.google.se/search?q=avisynth+sharpen&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:...ient=firefox-a . But you wont find any that are as good as in the movies, they can zoom 100x and still get HD quality in any kind of video.

For something a little simpler with a GUI you can try VirtualDUb.

If your videos are slightly soft, sharpening might help, although it will also enhance noise, which then requires a higher bitrate when you re-encode.

However if your video is out of focus, you will have very limited, if any, success.

Thanks. I will try VirtualDUb.

Know how they do it in the movies?

First they shoot the picture from far away and soften it a bit. Then they move the camera about a meter away and focus carefully. Then the pretend to zoom in stages by blending the two images.

You too can do that.


In real life you are limited by the resolution of the camera+lens. There are techniqies to average out noise if the object is stationary.

I am working hard on various Noise Reduction (pascal programming) projects, and to this
day, it has proven difficult but interesting. In my research, I am designing around the
following mediums: Laserdisc; Analog Cable; and VHS. Anyway.

fwiw ...

Noise Reduction (NR) is a complex process. I have been studying it for several years now,
and still am baffled by the various algorithms employed. Very intersting indeed. Most of
the code snips I have been searching around (for clues as to how it is all put together)
is plentyful though in c/c++/c# and not much in the Pascal language, of which my knowedge
is plentyful in. So unfortunately, my research on NR methods and algorithms consist of my
own design, from the ground up, using the Pascal programming language. Its not easy.

But, the bare basic building blocks are:

** Averaging (two or three pixels) .. ie, (p1+n1) / 2, or (p1+c1+n1) / 3 ...
** Matrix Averaging .. ie, dynamic and/or complex descision calcs and beyond

The matrix methods intail an array of values of surounding pixels within a Spacial area,
while the more advance methods intail Temporal and even Temporal/Spacial areas for
calculating pixel values for NR scenarios.

All these and more have been used in one form of Noise Reduction process or another,
via software. Course, there is also the hardware method. But that is another area,
though beyond the scope of the sofware and programing aproach.
