So after me range 32 it becauses unnecessary to encode any higher than, ok thanks ok ill try grain as for b-frames isnt it meant for compression? so isnt high values good? as for ref i always put it at 4, but when the encoding is done, for so reason the encoder sets it ref 3 (be it mod x264 or normal) as for lookahead i have the CPU power so it does not bother me. With all the setting set before it takes 45 mins - 1 hr to encode one episodes. With the settings you guys gave me, that time should decrease. But i'm not worry about encoding time atm. ok i will turn off DCT Thanks a lot If he wants to stay within level 4.1 then 4 is max. That doesn't seem to be the case from what I've read. Apparently some Blu-ray discs are encoded at 6 ref frames @ level 4.1 as well. http://doom10.org/index.php?topic=69.0 Perhaps maybe you are confusing the fact that some standalone players can't play more than 4 reference frames and can't work with video above 4.1 and making the wrong conclusion that 4.1 can't have more than 4 reference frames. Though they seem to be saying in that thread for compatibility sakes you might as well stick with 9 for 720p and 4 for 1080p so just for the sake of compatibility with various devices you'd probably want to stick with ref=4. It's 4am, I need sleep. that is the standard of ref, but like i stated above the encoder sets auto back to ref 3 so regardless if i choose ref 4 will set it back to ref 3. and yes Baal i am aiming for compatibility i already try these settings on my Blu-ray home theater system and games consoles, they all play smoothly with any lag or buffer problems Thanks a lot guys i'm going to try your settings and compare it with my old settings will post screen shots, between the new settings and BD source and my old settings and BD source

http://astrataro.wordpress.com/category/encode/x264/x264-bin/ here's what i use. I use it because it shows/unlocks more settings in x264, and is more optimize. Ok thanks for the tip you are right So any other things i need to change?

The only people I know who still use 2-pass is Shaq and DarkDream, but DarkDream also encodes to a specifically set filesize too. Neither of them have upgraded to ASS subs either. Shaq uses PGS and DarkDream uses SRT. i do use ass in most releases its usually dual-subs with untouched BD pgs and ass/ssa subs Ok thanks for the feedback ill start experimenting with CRF again. Before the start of this year most of my encodes where encoded at CRF @ 16

well from what i read from h264 doc's its not as efficient as automated 2-pass when it comes to compress and quality what do you mean? i am encoding in 2-pass or are seeing it's bad?

Hi, i'm asking help from all top encoders PC SPECS CPU: i7-4770k OC @ 4.2 ghz (liquid cool) PSU: 850W RAM: 16 GB (4x4 GB) @ 1600 HDD: 120 GB SSD, 8 TB HDD (multiple drives) GPU: NVidia Geforce GTX 660ti Here are my h264/x264 encoding settings, i want to know if i'm using good settings. If not can you tell me what i'm doing wrong, and explain why these setting or settings need be change and what will changing help improve? Encoding Mode = automated 2 pass TESTING Profile = High Level = 4.1 Preset = Very Slow Tune = Animation CHANGING Ref.

I want to know if i truly reach the limit or if there is a lot more i can improve on. its for 1080p encodes Encoder Settings Explained http://mewiki.project357.com/wiki/X264_Settings Thank you

An encode of anything is a 'downgrade'. No matter how you look at it, you're losing the original quality. Sure you can filter away defects, but in the end you're only destroying what was originally there. To be clear, encodes reduce quality by nature. An encode that goes quickly will reduce quality in a more noticable way than a slow encode. That extra time (as i understand it) is used by the software to reduce quality/bit depth in areas that wont be noticable. The more time given to this process, if done correctly, the more accurate (and close to the original) it will be. longer encodes can give better quality but in h.264's case that can mean using higer settings which leads to incerasd complexity for the decoder to decode that can cause artifacts by it self. for that reason it's better to let avisynth filters do the deblocking & noise filtering. it also helps to disable cabac whenever possible. plus too many people make the mistake of using the "High" profile with a low bit rate when they should be using "baseline". "high" profile is designed to work at a bitrate of 42,000 with 1280x720 video. no one in their right mind would download a video with a bitrate that high though much less upload it. yes but encoding in baseline is way to inefficient, encoding on baseline with the highest encoding settings there is a lot of noticable detail loss. Especially when you compare it to a encode, encoded in High profile. Now if you want good quality encode you should never encode in baseline, regardless of what you said about bitrate is irreverent compare to point of encoding
