Me gui encoding noise problem...

[WizardCoder]

I try to reencode noisy BD (old tv show), i want to remove noise before convert it to 720p DXVA2 8 bits MKV...

I use Megui + x264 video bitrate [6000;7000] i need to made some test to choose...

I already try to use noise option in megui, i can't see the difference (except 1 or 2 hours more on encodage)...

I would like to have an image more smooth but keeping edge, i known it's not easy...

If you have some tips or profile your welcome...

Thanks

Which MeGUI noise reduction parameters did you use?

Also, if it's random noise, the x264 --nr parameter can also be helpful. It only applies to predicted blocks, and so can do a decent job of preserving grain texture while not having the noise move a lot between frames. Start with 1000 and see what effect it has. The optimal value is probably quite a bit lower than that, so you'll want to iterate.

Also, I'm not sure what you mean by "bitrate [6000;7000]" Do you mean 6000 average 7000 peak? That's awfully flat. DXVA2 clients can handle much higher peaks than that at Level 3.1
