Question regarding ringing

[ubertoast]

I am not sure if this is a result of using aq and psy rdo, but lately my encodes have more ringing than usual. Here is a clip from a section of 24 that has an example of what i am talking about.

Pay attention from 12-17 secs, in the light background.

My question is, how can i go about reducing this effect? Is it something that can be done in x264 settings?

Thanks for any help.

Someone will probably offer some better advice, but my first suggestions would be to try lowering AQ strength and/or raising deblocking.

Ok, after trying several things, i realized it was the source that is so noisy/ringy. I tried to increase the denoising in the avisynth script creator in megui, but it ends up blurring the image too much for my liking. I guess i will stick with how it is for now until i get my hands on a better source.

Hi!Here is a clip from a section of 24 that has an example of what i am talking about.i realized it was the source that is so noisy/ringy...I guess i will stick with how it is for now until i get my hands on a better source.What better source could there be than your original DVD? If, as you say, the original is "noisy/ringy", I'm sure it's the same for all original versions of that DVD, so that exchanging yours for another new one would likely be a waste of time...

I was thinking of hdtv streams. But i would have to be lucky if they decided to play it again haha.

that's why he hopes for a HD broadcast, since he wants a better source.

Hi - and welcome to the Doom9 Forum!

I guess you didn't notice that "ubertoast saidBut i would have to be lucky if they decided to play it again I interpret the word "again" to mean that the already-existing problematic video was the captured from an HD broadcast...

[jeffy]

I would think "ubertoast" simply meant the series was already broadcast in HD, but they could not capture it at that time...

720x480 is SD not HD. Every 4:3 movie/video I have encoded has been at this resolution.

@DragonM, @jeffy

Why speculate?

Perhaps "ubertoast" will post back here to clearly state whether the ORIGINAL source for the converted-to-clip was an original DVD, an HD broadcast, or yet something else...

I don't see why it matters? Anyway, this particular problem is solved, if he wants to wait and hope better quality is somewhere out there, more power to him. (What could be better than DVD? Besides hdtv, which may not be :p, a bluray release? Not that DVD is always great quality, I've seen series broadcast in SD looking better than their overstuffed DVDs.)
