Hello. Recently I found a channel, with a very good quality stream. I asked a streamer what is bitrate, he said that about 2,600. So I set myself in a similar or even higher.

I downloaded a video streamer from twitch. I turned on the home recording, after which I turned on the video fullscreen. I turned off the record, but my quality is slightly worse than his. I do not know how he has achieved this quality, the Bitr about 2600. Below I give two screen shots from the original film taken from Twitch and my recorded video. you can see the difference.

Below is data from MediaInfo, can you help me with this.
Especially I'm talking about improving quality while moving the camera, the moment of sharpening is very fast.
And for me sharpen it takes more than a second. Here is screen, instant, right after moving camera: http://oi39.tinypic.com/o8ykip.jpg

I tried to change preset from veryfast to slow, but nothing happens.

Sorry for my bad language, I hope you have understood.

His video. Time 04:35.

Well, for one, it looks like something is wrong with your resolution settings. If you look at the screenshot of "My video screen" you can see that part of the screen around the bottom and right side are cut off.

Other than that, he appears to just be using the Veryfast preset, nothing else special. You should post an OBS log to make sure nothing was inadvertently set wrong.

Yes, I know my video is cut off, but I dont know why. I set resolution 16:9, so all should be OK.
Im wonderning, how he can get better quality, with lower bitrate (2600), vs my (3000).
Krazy you have PM on Twitch. I am very thankful.

I am using OBS with Dxtory (Lagarith Codec, 720p), becouse then I have more fps ingame.

I never compared lagarith/dxtory and OBS gamecapture, but for your sharpness problem, he is using:
keyint_min=9 and lookahead_threads=4
Both could have a slight effect on the "quicker sharpening" effect you mentioned. Last but not least you could do a visual comparison using OBS own capture functions to see if lagarith makes a difference. (Your example picture looked a bit darker)

Ok, Jack0r I tried use only OBS, with added that 2 commands.

His video screen: http://oi40.tinypic.com/2eygzn7.jpg
My video screen: http://oi41.tinypic.com/2ch2nba.jpg

He is using AverMedia, but I guess it is not the reason.

I think, nothing changes. Same quality.
Have you any idea?

My custom x264 commands:
8x8dct=1 aq-mode=2 bframes=1 chroma-qp-offset=1 colormatrix=smpte170m deblock=0:0 direct=auto ipratio=1.41 keyint=240 level=3.1 me=hex merange=16 keyint=96 keyint_min=9 mixed-refs=1 no-mbtree=0 partitions=i4x4,p8x8,b8x8 profile=main psy-rd=0.5:0.0 qcomp=0.6 qpmax=51 qpmin=10 qpstep=4 ratetol=10 rc-lookahead=30 lookahead_threads=4 ref=1 scenecut=40 subme=5 threads=0 trellis=2 weightb=1 weightp=2

Get rid of those custom settings and fix the resolution problems, then run the stream for a few minutes, then repost. Your log file is doesn't encode very many frames, its like you only had it on for a few seconds, and with all those custom settings, I'm not about to go through and decipher what they all do. Get rid of them, fix resolution problems, then post a new log from a minutes-long stream.

Also if you're streaming to Twitch your key interval isn't set correctly.

If you want to stay comatible with Twitch's requirements, set the keyframe interval to 2.

The log only shows 4GB of RAM in that case because you're running the 32bit version. If you run the 64bit version it will see all your RAM (such as in the first log you posted).

Be sure to use a wired connection, not wireless. I don't use a laptop but pretty sure others have encountered and solved the green screen problem, see what a forum search reveals. Btw, your key interval is now correctly set :) .
