MeGUI x264 presets. - Page 41

He's using the old profiles, the "insane" profile now is just crf 17, not a 2pass.

There have been many changes to x264 since Sharktooth did those profiles and their use is strongly discouraged. The megui profiles as they exist now are more or less simple device presets with crf going from 17-23 in 1.5 increments and a 2 pass for each device. 2pass is only needed now when you need an exact target bitrate.

So on all presets you're encouraged to change the speed to your preference and use the bitrate calculator to find bitrate. Then just save them as you like them.

So, how do I change the new Insane preset to give me the same quality as the old one? I realise that its use may be "discouraged", but the bottom line is that I am encoding 720p on an extremely tight bitrate. The old preset took a long time to encode but the results were worth it. The new preset doesn't give me the quality I need.

I'd be happy to a straight A to B comparison, but right now I can't, since I don't have the old preset any more!

Try with 1pass crf=17 preset= more slower as you can..

@easy2Bcheesy

import my attempt to duplicate it x264_dp_ iNSANE2.xml

let me know how the project comes out i just might duplicate all of them to the new switches

easy2Bcheesy · 15th January 2010, 21:28

That is an enormous improvement on the new Insane - many thanks

MuLTiTaSK · 15th January 2010, 22:05

@easy2Bcheesy

your welcome i'am glad you liked it

alot has changed with x264 since ST created those older presets the lastest presets are mainly using x264 defaults with specific tweaks for devices rather then quality reason you noticed the quality loss

carlo_0000 · 16th January 2010, 21:30

hello
i update megui today and the profils

but

it that normal that 1 st pass is 2 times slower than before ?

i olways use best quality insane dxva profils

and when i start the queud jobs it take some long time before cpu is used (i see only disk acces)

i olso notice that x264 use more that 1 gigas of the pagefile.sys and slowdown the computer performance

with the old megui the 1st pass starded immediatly (using the cpu)

QuadraQ · 17th January 2010, 02:38

Just updated megui and got the new profiles (they look good). I've used the AVCHD in the past, and it was a two pass encode. The new one "AVCHD (DVD5/9) - High Quality" seems to be running as a one pass. Are you using some new magic in x264 to accomplish this?

Another question: The unrestricted profiles and the DXVA profiles seem to have been consolidated. Does this mean that I can take advantage of my DXVA compatible system (for greater encoding speed) while still creating an unrestricted x264 MKV?

nurbs · 17th January 2010, 09:09

Depends on the hardware you have. If you want to be 100% sure it plays you should restrict it to level 4.1 and set the appropriate vbv parameters. As long as you don't manually enter the number of reference frames the --level setting will automatically restrict the number.

rtjnyoface · 17th January 2010, 09:31

You could use mediainfo on some of the files you used your preferred configuration on and it will at least give you some ideas as to what new preset could be considered the same. Mediainfo will give you a couple of things such as the # of reference frames, the level of subpixel refinement, trellis use, I'm not sure what else ATM.

So increase the amount of analysis, reference frames, motion estimation and such.

You might have to if you aren't able to have a final product similar to what you had prior to the changes.

Hope it helps somewhat. (Ha, put it on placebo

).

I have found than in my MeGUI "Unrestricted (DXVA)" X264 profiles is everywhere Trellis disabled.
I am confused - either something is wrong either I do not understand it well.

I always thought Trellis does not affect decoding, at least not to corrupt HW compatibilty.
I have also always thought at least Trellis=1 is needed for SubME 6+ for RD optimization.

ZEXEL · 17th January 2010, 15:28

I've been update to new MegUI version & find all new preset profile also I really happy with that, but could you tell me where is the same/better quality picture profile for "x264: Standalone-HD-DVD" since it gone... cheers...

ShadowVlican · 21st January 2010, 22:15

hm.. i guess someone should edit the first post of this thread to notify newcomers that the profiles are now obsolete

and perhaps remove them from MeGui altogether

iko417 · 22nd January 2010, 03:52

remove them, never used them

Wikke · 22nd January 2010, 19:34

I just updated to new presets in Megui. I have always used Standalone AVCHD presets and I was satisfied with the results. Normal speed for:
720p encoding was first pass 115 FPS and second pass 85 FPS. Needed time for encoding the whole film was 1 hour.
1080p encoding was first pass 55 FPS and second pass 45 FPS. Encoding time for the whole film was 2 hours.

Now with new updated presets the whole encoding is taking much more time to finish the job.

I am now encoding 1080p material with Standalone AVCHD presets and the framerate for first pass is only 15 FPS!!! I guess the second pass will be only 5 FPS.
Are the others facing the same problem, or is there something wrong with my updates?

Is the quality with new presets really so much better that it is taking 3 times more time to finish the job?

blsbball · 24th January 2010, 23:49

Anyone else notice any downgrade in quality from the older unrestricted const quality insane x264 and the new dxva unrestricted? I feel like the older profile, although it produced a larger file, produced much better results.

Reformulated question - is Trellis safe to use for DXVA ( and evantually HW players ?

J-Wo · 27th January 2010, 07:46

I'm trying out these presets with MeGUI to convert my DVD rips to MKV for better playback compatibility with my WDTV Live. I want to preserve quality so I'm thinking of using the DXVA-SD-Extra Quality preset. How does this differ from Standalone-PS3-Xbox360? I know the WDTV Live is less restrictive than PS3 or Xbox360, so maybe I should try Unrestricted 2pass Extra Quality? I'm not sure what file size/bitrate I should aim for but will ~2000 kbps (2cd file size) yield good results? Thanks.

Trellis is purely an analysis option and therefore doesn't influence hardware players.

Beak · 29th January 2010, 00:58

Hi. I hope one of the devs will confirm or assist the slowdown in encoding speeds. I am crawling now at about 2 frames per second with the X264 Unrestricted 2 pass Extra Quality Preset.

The commandline reads

program --profile high --preset fast --tune film --pass 2 --bitrate 12228 --stats ".stats" --thread-input --b-adapt 2 --ref 3 --rc-lookahead 40 --me umh --direct auto --subme 7 --partitions all --trellis 2 --output "output" "input"

I would prefer to have the speed back as it looked quite good to me before.

Can anyone tell me what the arguments used to be for this preset?

Is there anyplace one can download the previous version of Megui and its updates?
