Avisynth: Additional Noise Reduction for Optimal Script
 

Hi everybody...

I know many people are discussing this right now in other threads too.
What I wanna know is how are you all treating "noisy" DVDs. When I use the current optimal script on those I can clearly see how artifacts are enhanced and image quality is not very high after encoding. :roll:
What are your tweaks to the optimal script to kill the noise?

Just give Deen set to spatial NR-settings a try instead of the StmedianFilter line. As Kwag told only to rise up the spatial denoising before the MA routine starts. If I understood that right.

Or stop using Asharp. It sharpens everything, including noise.

ok, thanks a lot for all your input guys, spend the last 2 days with testing different approaches to clean this horribly noisy DVD (Money Train PAL)

What can I say... Deen helped, in fact it looked better than with STMedian Filter, however it seems to me that there's less overall noise but more mosquito noise with Deen... :roll:
I also stopped using aSharp and lowering the resolution to 480x576, but I still don't like the quality of my final MPEG. You know I guess there are movies around which are so "dirty" mastered, that you can't compress them properly at all without getting horrible artifacts... :evil:

however thanks a lot. Any further ideas are greatly appreciated!
