Bad frames

[Metal]

Hi guys.

I don't know if this is the right place to post this, but I was searching for a way to solve the problem with bad frames like below images:

The question is, is it possible to fix this problem?
if so, please tell me how.
Thanks.

I see lots of blocking, for starters you can use a deblocking filter: http://avisynth.nl/index.php/External_filters#Deblocking

Thanks for the quick answer.
Yes, you're right. I've tried deblocking before the results were OK, but not good because you lose details.
some of these bad frames have too much Luma noise and Chroma coloring problem if I'm not mistaken
I was looking for a way to recover these bad frames if possible.

I suggest you use frfun3b(S=8), dfttest and/or DeGrainMedian(mode=3).

Or try this alternative: Here. (http://forum.doom9.org/showthread.php?p=1582950#post1582950)

Thank you.

I've tried denoisers, but the results was not what I'm looking for :(

You can also use Deen, FFT3dfilter, dctfun4b, frfun3d or BlindPP, but in my opinion frfun3b is the main option.
To mitigate the strength of these filters you can use MC or with Contrasharpening.

Did you check the alternative?

I use QTGMC in progressive mode followed by Gradfuin3() for deblocking quite a bit, but I almost never encode animation so I don't know if it'd be as effective as it is with video/film. (QTGMC denoises better than most denoisers).

QTGMC(InputType=1, Preset="Medium", EzDenoise=1.5)
gradfun3()


There's some deblocking cleverness being discussed in this thread.

yes, I've checked the alternative and I liked the result. Thank you.

WOW!
What a nice filter!
Thank you hello now I'm gonna play with this filter.

If you're referring to QTGMC, keep your eye on the result when using it on animation. Sometimes it produces artefacts for reasons I don't understand. Sometimes it's fine and sometimes not.

Although I had a theory (http://forum.doom9.org/showthread.php?p=1713587#post1713587) as to why, but I don't encode animation much so I haven't tested it.

On occasion I've seen similar things when using QTGMC for denoising video/film, but it's not as common and much harder to spot.
Most filters tend to be some sort of balance between the desired function and unwanted side effects. I find QTGMC has a much better noise removal to blurring ratio than most noise filters, especially where there's movement.

If you were referring to the filter being discussed in thread I linked to, I've not used it myself.
