View Full Version : filter to calm jittery luma (only)

is there a filter that only works on the luma-level (or possibly chroma)?
I have 29.97 source material that I run through a script that

deinterlace
ConvertToYV12

and msmooth
(to calm bigger areas of simular type)


when I preview in mediaplayer it looks fine but after re-encoding it
it turns out bigger areas of similar texture that looked fine in mediaplayer turns (flickery) blocky,

think the encoder is very sensitive to lumalevels,
I tried different smoothing filters but all makes the target visibly loose detail, so I'd like to keep the detail pixels and only work on the luma (and possibly chroma) level (temporal?),
is there a filter to calm jumpy luma (fade more?) like this?

note: I'm a total newbie to this so sorry if I misunderstood anything

not sure if it will do what you ask, but you can try the Antiflicker (http://www.avisynth.org/warpenterprises/files/antiflicker_25_dll_20030304.zip) filter by neuron2. intended to level luma variation for film captures.

Maybe I'm interpreting this wrong, but I've dealt with flickering pixels (more like lines), defined as pixels that cross threshold on one frame and fall under it in another,(it being any filter) creating a flickering efffect that is magnified in pans. Any decent antialias filter should solve that.

If the flickering is more like a whole image shimmer, not much can help there beside antiflicker. Perhaps attack the areas by hand?
