You uploaded for comparision good quality sample, how you obtain that
sample? Could you provide that sample with intro part? I asking for
intro becasue intro part will show me most what quality should i strive.
Did you try with noise reduction?

Ok, more denoising and small tuning:

thank you, I tried you command but the quality is still lower than the
other one..

unfortunately this does not make differences in results either:
Then i can think only about that:

The problem is that when I pause both videos at the same scene, the other
video is so smooth and you can't see any noise, but mine is not like that.
It seems they have used some video filter or something to Remove the noise.

You do not need second pass with constant bitrate, but with 2 pass - in
first pass it log where it need bitrate and use that knowledge to
distrubuate in se
this is the source video mediainfo:

Please don't top post on this list - reply in line like I do here.
you mean bufsize could affect the quality??
A bit, but I don't know how much in this case, just that it
I used this command but the quality is still the same. does deblock has
something to do with this? the second video that I want to reach has
smoother frames, mine seems to have a lot of noise.

So you set own x264opts then you use preset slow what rewrite x264opts..
If you reencode h264 with downsacale try with minimal settings like:
ffmpeg -y -i in.mp4 -vf
pp=va/ha,scale=1280:720:flags=spline+full_chroma_inp+full_chroma_int+accurate_rnd+bitexact,setsar=1
-an -c:v libx264 -preset ve
I am trying to reach that quality and using those parameters but the result
is still low quality..

I removed zerolatency but I am not getting a impressive result.

Look at the differences in the params you pasted
bufsize 3000k (you) vs 5000
I have encoded my videos using ffmpeg and H264, and this is my ffmpeg
