What is the best filter I should use in this specific case?

[retaining1]

I have some files, and I want to reduce their size to 99MB exactly (I use x264 2pass), usually the files are in 720p and average 400~500MB.

I would like to remove the noise to exactly the same as it is in this image below: (left as I want, right is how my encode is coming out).
Can anyone tell me which noise filter I should use?

Bitrate is too low and hence you are getting visible macroblocks in encoded footage.

Yes, I know that, but this image you see on the left also uses the same bitrate encoding, with 2pass 99MB output, but it uses some filter that smoothes the macroblocks, do you have any idea?

You may try MDegrain filter

Firstly, what encoding app are you using ??

And how do you expect to get decent quality at that file size. !!!

I would strongly suggest using some SMDegrain pre or sub filter.

Im Using StaxRip, I tried MDegrain, but the encoder time from 4 minutes went up to 3 hours, the problem is not the quality, the quality is exactly the same as the photo on the left, the difference is exactly in the smoothness, the one on the left has the impression of better quality because the macroblocks do not appear(because of the smoothness), but the quality is exactly the same, there is no difference, the difference is the smoothness! I will send you 2 links for you to compare the videos in real time.

take note that the file on the left which I want to get to the same filter, was also encoded at 99mb.

It would have been better if you had of uploaded the actual file you're working with, instead of that.

But it looks like the "original" is pretty bad quality to start with

Not too much you can do with that..

With which x264 settings is that? default?

I think x264 psy-rd could cause such blocking and does not work well at low rates.

Have you tried with "--tune ssim" or even "--tune psnr" for getting rid of the little blocks? Maybe increase deblock to 1:1 or 2:2 ?

yes default, thank you for your tips, improved a lot, I'm using it too Depth 10-bit, helped.

Well don't use 10bit with H.264, its a decoder compatibility nightmare. Low rates do not really benefit much from high bitdepth anyway.

Thanks for the info, it helped a lot =)
