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.
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...
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...

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