 you can check the code and use as a start for a better implementation.

 We found that using gaming techniques: up-scaling low frequency areas

 quite efficient for the vast majority of our renders where the plate is
 gigantic or a large kernel size is needed.
 The result is perceptually indistinguishable.

BCC 10 from Boris FX has a filter called Damaged TV that generates this look.

[Nuke-users] Boris Continuum Complete for Nuke - beta testers wanted

2013-12-12 Thread Peter McAuley 
Hi Folks,


I would like to invite you to join in our beta program for BCC 8 Nuke. This is 
our first foray into the Nuke UI and although we've done a lot of work to get 
this far, I suspect there will be some workflow issues that we have not 
anticipated and to assist in that regard, we are reliant on your knowledge and 
feedback.


For those of you who are not aware of the BCC product, the toolset is comprised 
of over 200 VFX and compositing plug-in filters, which include image 
restoration tools, stylized film looks, 3D hardware accelerated particle 
systems, lens flares, 2D volumetric lighting etc etc. If you would like more 
information on the filter set prior to signing up for the beta, please feel 
free to check out our website: www.borisfx.com ... although there is no Nuke 
specific content available on our site just yet, almost all of the filters that 
are available for other hosts will be included in the Nuke installer.


With that, here's a link to the beta sign-up page:


http://www.surveymonkey.com/s/RPNRT7L


If you are interested in checking out the plug-ins please click on the link and 
sign up - we'll then follow up and provide you with a link where you can 
download the software. We look forward to your feedback in helping us sculpt 
and finish these plug-ins so that they feel natural and easy to use in the Nuke 
environment.


Cheers,


Peter.___
