MeGUI x264 presets.

[Sharktooth]

no and no.
quicktime has its own preset... same for xbox 360 and PS3.

[[DB-FR] Nikko]

So the last solution for me is to use the Unrestricted 2pass Anime_Toons HQ preset ?

[Sharktooth]

that would be incompatible with most devices including PS3 and xbox 360... and probably even with quicktime.
you should choose the minimum common denomitator between all those presets and make a new one.
...different devices need different settings...

[Tacio]

what about L5.1 dxva support preset? Or there is no major difference with L4.1 preset?

[Adub]

Uh, I think the reason is that L5.1 is not officially supported by DXVA, yet. I heard that Nvidia is adding support through their graphics cards, but that is all that I know of.

[Atak_Snajpera]

There is only one small difference :) Max bitrate can be higher than 50 Mbps and resolution can be higher than FullHD. (http://en.wikipedia.org/wiki/H.264) Now ask yourself how often do you encode above that limit.

[Tacio]

but... if I will change only L4.1 to L5.1 in dxva preset and other setting leave without changing is quality of encoded video would better? :)

[Adub]

No. It should stay exactly the same. The only difference is that whatever you use to play may only look at the L5.1 flag and say that it is not DXVA compatible, when in actuality it is. Just leave the setting flag where it is and don't bother with it.

[Tacio]

thanks for explanation

[Great Dragon]

Presets archive is corrupted (download only 10 bites). Please fix it.

[buzzqw]

the download is ok

try with another broswer

BHH

[Great Dragon]

Thanx, dont even expect Firefox bugging ;) EI7 is ok.

[atreides93]

Has anyone come up with a pre-set for the new Android based phone (Tmobile G1)?
I wonder if the iphone preset will work. I am going to try it soon

[AntiJw]

Sharktooth, could you please do some "x264: Standalone-Blu-ray HQ" preset? With subme 9 and so on. I don't know what's the highest possible quality limit-settings for this compliancy.

[pelle412]

I apologize if this has been answered before, but I couldn't find the rationale behind the use of trellis 2 in the standalone PS3 and BluRay profiles? I know it can be changed by the user but it's a really slow feature :-)

[pelle412]

I know but why was trellis 2 added after such a long time? I can't find the explanation. It belongs more into a semi-insane profile.

[Sharktooth]

blu-ray presets are of 2 kinds: fast and quality.
trellis 2 is in the quality preset and helps retaining the massive amount of grain present in most blu-ray titles.

I'd like to point to a question i put to Dark Shikari about BR compatible streams here: http://forum.doom9.org/showthread.php?p=1213940#post1213940

In the thread i pointed too there was a suggestion that usingx264 with --partitions all set would be the best option for encoding HQ L4.1/BR compatible streams. I've tested this, and it seems that my BR player (Panasonic BD30) has no problems with P4x4 partitions used (i.e --partitions all) during encode.

MeGUI has P4x4 disabled on it Blu-ray profile, i don't know what the original reason was for that, but my opinion is that we reconsider this and update the profile to use all partitions. It would achieve better quality too.

[Adub]

No, not necessarily. p4x4 has been disabled, not for compatibility reasons, but for quality reasons. There were some tests run a while back where p4x4 actually hurt quality. There were only a few cases in which it actually helped, and I think those were at low resolutions, but don't quote me on that.

[Dark Shikari]

No, not necessarily. p4x4 has been disabled, not for compatibility reasons, but for quality reasons. There were some tests run a while back where p4x4 actually hurt quality.Extremely doubtful, especially now that x264 does full RD optimization for subpartitions...

hi,


i have a question regarding profiles in megui.

i have an iphone and my girlfrien a psp.

i found that encoding with iphone profile will result in a .mp4 (h264 + aac lc) file that is not recognized by psp and encoding with psp profile will result in a .mp4 (h264 + aac lc) file that is not recognized by iphone.

to avoid double encoding i ask if it is a middle ground profile for both iphone and psp...


best regards

p4x4 is coming back since this: http://git.videolan.org/gitweb.cgi?p=x264.git;a=commit;h=a0a1bfac7f4a09159f6ef2bf13fb69548b6c5a02

[forum king]

hey!!
recently i tried to convert some of my DVDs to a smaller size with MEGUI as everyone is doing this these days.
i used the profile named x264 unrestricted 2 pass HQ.
but i am not able to decide what should be the ideal size of the resultant rips , as i have seen too much blurring of the edges.
could some one suggest what is a good profile for this purpose or which is a good profile + what more changes i can make in that profile so that i get a good quality low sized film.
thanks

Ah, I see I was running on old information. Okay then, let's turn on the p4x4.

Edit:
@Forum King,
That profile is just fine. Changing your profile will not directly affect your size. Changing the bitrate will. You can use the bitrate calculator to calculate your desired bitrate if you want, and then use that bitrate with the 2 pass unrestricted hq profile, and you should be good to go.

[Sharktooth]

no-one made it, btw it should be pretty simple to make. look at those presets and make a "minimum common denominator" preset between the two...

PSP does not support CAVLC :)
iPhone does not support CABAC :)

So now you should know the answer why you cannot create one file for two devices

[Sharktooth]

oh... then you're doomed...
there's nothing you can do.

[ThrottleAbuse]

Any idea on why a RAWAVC file created with the standalone-HD-DVD profile would have an aspect ratio of anything other than 16/9 when the AVS script is calling for a 1920:1080 file?

[Adub]

And what happens when you mux that raw avc file into a container and set the aspect ratio flag to 16/9?

[ThrottleAbuse]

I am using tsMuxeR to mux and I don't think it has that setting. I am using H264info to change it from 23.996 fps to 29.97 fps with pulldown and I have tried to use the setting in h264info to flag the aspect ratio, but that just seems to throw off the height and width. Maybe if I set the aspect ratio flag and the height and width in h264info it will come out right. I will try that.

I just figured that the probem could be fixed somehow with MeGUI so it doesn't happen anymore.

[b66pak]

actually you can...PSP cabac-only spec is obsolete (outdated)...

for who is interested in encoding for both psp and iphone this works:

cabac=0 / ref=1 / deblock=1:0:0 / analyse=0x1:0x111 / me=hex / subme=6 / psy_rd=1.0:0.0 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=0 / cqm=0 / deadzone=21,11 / chroma_qp_offset=-2 / threads=8 / nr=0 / decimate=1 / mbaff=0 / bframes=0 / keyint=250 / keyint_min=25 / scenecut=40 / rc=2pass / bitrate=703 / ratetol=1.0 / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / aq=1:1.00

in megui on encoder settings field select x264: Device-iPhone profile...click config...select RC and ME tab...change VBV buffer size to zero...change VBV Maximum Bitrate to zero...select Main tab...change AVC level 3 to level 2...select New and name it Device-iPhone&PSP.

to work on PSP it must be 480x272 (i tried 640x368 and it did not work)...if you find other working resolutions please post it...for better quality you can modify the number of reference frames in RC and ME tab (i tried 3 + mixed reference frames on/off and it worked)...

L.E. it works with AVC level 2.1 too!

[ditche]

Hi, is it possible, if it's useful, to create a profile Unrestricted 1pass Const. Quality for anime/toons ?? :)

[Sharktooth]

yes. will add.

[ditche]

Cool :thanks:

[Sharktooth]

just bear with me, i have very little time to work on it.

[poisondeathray]

Just a couple of typos:

"XviD_dp_ Const. Qusntizer 2 FAST.xml" => should be "Quantizer"

"Nero AAC_dp_ NDAAC-HEPS-32Kbos.xml" => should be "Kbps"

[alc0re]

Question about your standalone bluray profile.

What's the difference between yours (sharktooth) and
XolocoTuxmaster's profiles found here? http://www.mediafire.com/?f1zgyj5mn3n

I'm almost a complete nub when it comes to this...I was reading a tutorial for converting blurays to AVCHD compliant videos that will fit on a dual layer dvd and play on my bluray player, and it said to use XolocoTuxmaster's profiles. I don't care about how long the encode takes, I just want better quality at a given bitrate. Which profile will yield better quality at a given bitrate?

[Sharktooth]

@poisondeathray: fixed in next presets version.

@alc0re: i never heard about XolocoTuxmaster's presets...

[disklib]

Hello everyone, this is my first post, but I've been lurking in the forums for awhile, mostly in this thread and it's predecessor. I know it's been said already, but without these presets I would have had no idea how to begin using Megui. So thank you Sharktooth for creating/maintaining them, and to everyone else who helps with their ongoing development.

I'm trying to learn Megui so I can create a HD-based library on a general PC. I'm not targeting maximum file sizes, bitrates, or compatibility w/ specific devices. After various tests on live-action material I've settled on using the "Unrestricted 1pass Const. Quality HQ" preset. I adjust the "quality" level up/down depending on the source and have been happy w/ the results.

Now I'd like to try encoding animated material, but I'm not sure where to begin. Specifically, I'm confused as to why there isn't an "Unrestricted 1pass Const. Quality Anime" preset. Is 1pass or CQ somehow at odds with the goals of compressing this type of material?

[nurbs]

For cartoons take the "Unrestricted 1pass Const. Quality HQ" preset, disable psy-rd and maybe aq and you are good to go.

[Adub]

You should have lurked more.
http://forum.doom9.org/showthread.php?p=1217460#post1217460

[disklib]

@nurbs - Thank you for the suggestion on which settings to adjust.

@Merlin7777 - I must have overlooked that post while waiting for my forum activation e-mail. It took almost a week to arrive, due to the holiday I suppose. Thank you for pointing it out. I'll be sure to look for it when the presets update.

And based on Sharktooth agreeing to create it, I suppose that answers my question on whether 1pass/CQ is applicable for animations.

[bottomsup]

Hi,

Does anyone know what settings I can use for a Blackberry Storm?

TIA

[nurbs]

Look in the manual. It has to say somewhere it supports profile x at level y. If you tell us that we may be able to help you.

[AntiJw]

What are the restrictions for Popcorn Hour (PCH)? I thought it was as "x264: DXVA-HD..", but I'm not sure if it's "x264: Standalone-AVC-HD"..

both should work.

[AntiJw]

both should work.Thanks, I'll use DXVA-restrictions then, because it allows better settings (16 bframes, higher bitrate etc.), which is good when encoding 1080p.
