MeGUI x264 presets.

[smok3]

a. maybe stick a x264 version somewhere in that xml (like. compatible with x264 vXYZ and maybe higher)
b. what is the default subme now? 6? is psy-rd default as well? (i know i read that somewhere, just can't find it now...)

[J_Darnley]

smok3, x264 --longhelp is a source of defaults and yes, subme is now 6 by default and psy-rd is on with strength 1.0 but psy-trellis is off.

[juGGaKNot]

Can/is x264 lossless be DXVA ? i want a "HQ" copy for myself so i'm thinking lossless but i want to use my CFG card for decoding.

[Sharktooth]

no...

[Ramir Gonzales]

Any idea why psy-trellis is OFF even in Insane profiles please ?

[RunningSkittle]

read comments on first page:
V78: Removed Psy-Trellis (set to 0) in all presets coz it's too much experimental. Set b-adapt to 2 where it was possible without hurting speed too much and on all the Insane presets.

[smok3]

how come there is 16 b-frames on balanced profiles?

[RunningSkittle]

because it is using the old bframe decision
B-adapt 2 with 4 bframes is better than b-adapt 1 with 16.

[smok3]

ok, tnx, i'am slowly getting up to date :)

[fields_g]

In V81, "Unrestricted 1pass Const. Quality Insane" has subpixel refinement set to 7 while all other Insane profiles have moved to 9. Was this overlooked or is there a purposeful reason for this?

[Sharktooth]

that a plain mistake.
ill correct it as soon as i get 5 free minutes...
tnx for reporting.

[Dark Eiri]

Hey Sharktooth, are you planning to change the PSP profile, now that is confirmed that it can play 16 b-frames?

[Sharktooth]

no coz b-adapt 2 with 3 bframes is better than b-adapt 1 with 16... and b-adapt 2 with 16 b-frames is so slow it isnt useable.

anyways, presets updated: V82.

[rack04]

Does it matter that --sar 1:1 appears twice in the blu-ray profiles?

[blizzbit]

Hi Sharktooth,

I just want to point you to these threads regarding the Blu-Ray profiles. Take a look here (http://forum.doom9.org/showthread.php?p=1192939#post1192939) and here (http://forum.doom9.org/showthread.php?p=1197218#post1197218).

It's about the Blu-Ray Max VBV buffer = 30000 kbits.

Is x264 supposed to be this CPU intensive?

With a 3,6GHz Core 2 Duo & CoreAVC I'm unable to playback smoothly a 1Mbps 656x368 59.94fps x264 video (drops a few frames every now and then because CPU usage goes over 50%).
When a 29.97fps interlaced DVD is deinterlaced properly, it should be 59.94fps, right?

If i encode it to a 29.97fps video, the CPU usage caps @ 26% and the playback is smooth.

I tried out DXVA-SD-Balanced(& Extra Quality & Fast) for encoding.

With DXVA (GPU decoding) enabled both videos play smoothly with no problems.

[Nightshiver]

No, if a 29.97fps video is DEINTERLACED, it will be 23.976. If it is BOBBED, it will be 59.94. As for x264 being CPU intensive, I would say yes.

[Damie]

No, if a 29.97fps video is DEINTERLACED, it will be 23.976. If it is BOBBED, it will be 59.94. As for x264 being CPU intensive, I would say yes.

Then why does 29.97fps DVDs play at 59.94fps when Purevideo is enabled?

Also 1080i50 videos are played at 50fps when watching with Purevideo HD enabled.

In both cases the video is very smooth and high quality.

[Dark Eiri]

No, if a 29.97fps video is DEINTERLACED, it will be 23.976. If it is BOBBED, it will be 59.94. As for x264 being CPU intensive, I would say yes.

If a 29.97fps video is deinterlaced it will be 29.97fps. If it's inverse telecined, it will be 23.976fps.

[Nightshiver]

Yeah, I was going to edit my comment when I saw that. It was a little late last night.

"Converting a DVD of music videos in interlaced MPEG2 format to a progressive MPEG4 stream. For these applications, an output framerate of 59.94fps or 50fps is too high. Instead, most deinterlacer filters convert every interlaced frame to one single progressive frame, effectively halving the framerate of the content."

I'm actually converting a DVD music video. So does this mean, 59.94fps would be the right choice for x264 but it's too CPU intensive? If not, why does the original DVD play as 59.94fps when played with Purevideo?

[Nightshiver]

There is no right or wrong. You can do either and it will be fine, it just depends on what you want to do.

[pooyanunited]

HI,
I want to convert MPEG2 files recorded by DVB card SkyStar 2.6D to X264.
Which one is better for me? Unrestricted 2pass Balanced or Unrestricted 2pass HQ or Unrestricted 2pass Extra Quality or Unrestricted 2pass Insane?
I mean is it really any major difference between 2pass Balanced and 2pass Insane for me? cause 2pass Insane takes a long time...
tnx in advance

[Adub]

1) What are you yelling about? That is what the color says to me.
2) Well, of course insane is going to offer you better quality, but it will come at the cost of speed.

3) Here is a grand idea, why don't you run some of your own tests, and then figure out for yourself?

You are the only one who knows "which is better" for you. Oh, and that reminds me. We have a forum rule about "best".

Hi
Because I'm a ManUtd fan, I always use the RED color, sorry for inconvenience...
I used all of them and I didn't recognize any difference in picture quality! maybe I'm not so accurate or my sample video was not suitable to show the difference...

[Adub]

Well, I would just use the fastest one for yourself then. If you cannot see a difference, then great for you. Use the fastest profile that you can stand then. Problem solved. I can notice a difference between the profiles, but then again I have been encoding video for years and I am stickler for quality. But if the faster profiles work for you, then great, use them.

And wich one is the faster no matter of quality :devil:

EDIT: "Turbo"-mode seems to be default now (I saw), so nm :P

[Adub]

If you don't care about quality, then the fastest one is, you guessed it, the one with "Fast" at the end of it. And I know that there are about 4 of these, but if you read the rest of the profile's name, I am sure you can pick out which one is right for you.

Really, this isn't exactly rocket science here people.

[boissy]

DSidn't find the turbo one :script:

It's not something you put in the script... edit the profile.

OK, thank you, I found it.

Thanks for these, incredibly useful for new people like myself.

I have a PS3 and rip my own BR's, what would produce the best quality out of

Standalone-PS3-Xbox360

and

Standalone-Blu-ray

(or does anyone recommend another preset?)

?

Speed isn't really an issue, I have a good rig.

Thanks :)

12) How NOT to post on this forum:

...

Do not ask "what's best" because this question cannot be answered objectively. Each and everyone has their own view about what's best in a certain area. The best is what works best for you!
forum rules (http://forum.doom9.org/forum-rules.htm)

[Audioboxer]

How is the quality of the video "up to each person" ?

Whatever produces the highest bitrate will generally be best...

I don't know what all the figures mean in MeGUI so I was asking what out of those presets will produce the higher quality video.

I would try myself, but not understanding what all the figures and settings mean coupled with encoding taking quite a while, I thought I'd quickly ask as opposed to waiting 10+ hours to encode two files.

But alas, sorry.

[Sharktooth]

there is no best as per forum rules. the "best" is what is best for you and no one can tell what's best for you. please DONT ASK WHAT'S BEST. it is NOT ALLOWED in this forum.
in order of compression (hence quality) the presets are in this order (lower to higher): Fast, Balanced, HQ, Extra Q, Insane
keep in mind the higher the compression, the higher the time needed to compress (insane presets are insanely slow...).
for general use, i usually recommend 2pass unrestricted or DXVA, balanced or HQ presets.

Does this http://git.videolan.org/?p=x264.git;a=commit;h=a0a1bfac7f4a09159f6ef2bf13fb69548b6c5a02 mean that p4x4 should be enabled again for profiles with subme >= 6?

[Dark Shikari]

Does this http://git.videolan.org/?p=x264.git;a=commit;h=a0a1bfac7f4a09159f6ef2bf13fb69548b6c5a02 mean that p4x4 should be enabled again for profiles with subme >= 6?No, p4x4 is still not very useful, its just that where it is useful, its more useful now than it used to be.

I'd say if you had to pick a profile to turn it on in, the best choice would be the slower version(s) of an anime preset.

[vega22]

Hi,
I have a question that i think it´s not yet treated:
I think we need a separate template for video-on-web purposes. For sites like Vimeo or Blip.Tv where we can upload high quality mp4 files, i.e. The Ipod profiles i think not are optimized for streaming/progressive download uses.
For this target, im now using the dxva-sd-HQ, bitrate=400. But im still confused about the optimal values in vbv buffer size and vbv maximum bitrate. Does anyone could advise me on these two settings?

[Sharktooth]

that depends on the service provider.
the buffer and maxbitrate in DXVA preset must NOT be changed since those presets are supposed to be for DXVA compatibility and not for web streaming.

[vega22]

Thanks, Sharkt.
Well, i use the dxva profile only as a base for my custom streaming profile. I need CABAC, ref-frames, B-frames and so. Level 3.1 i think is good for that purpose. I just finish encoding some videos @ 400 bitrate/1000 vbv buffer/1000 vbv max bit. Quality ok+ for streaming. The problem now is Mediainfo says me that the stream max bitrate reach 1800.

[Sharktooth]

did you use 2 passes?

[vega22]

did you use 2 passes?
Of course, automated 2-pass. But i think now that the problem is a bug in the Mediainfo, because when i play the created files with ffdshow and look into info&CPU/movie FPS, the amount of INPUT BITRATE in real time never goes beyond 1000, even in the scenes more complicated and fast.

[AntiJw]

MeGUI should set "--deblock " instead of "--filter", which could be confusing for some people. And in x264's --longhelp it says "--deblock".

EDIT: Thanks Sharktooth, for changing that now.

[[DB-FR] Nikko]

Hi everyone, I have a question about compatibility. Is the DXVA-HD-Anime_Toons HQ preset compatible with PS3/Xbox and Quicktime (on Windows and Mac OS X), or it is already to "strict" ?
thx,
Nikko
