MeGUI - x264/XviD/lavc/Snow encoder with MP4/MKV/AVI output & audio

[Sharktooth]

Set B-Pyramid to Disabled in the profile.

(Yes, im back...)

[Capsbackup]

(Yes, im back...)

Great! :) I've always appreciated your efforts, so it's good to see you back.

[unknownsoldierX]

Since you're on 7, have you tried using the win7dsfiltertweaker tool?

Forgot about that tool. I changed AAC decoding from Microsoft to ffdshow and MeGUI processes the file without any problems! Thanks!

[tebasuna51]

The info of the output file make by XmediaRecode:
bframes=0

The info of the output file make by MeGUI:
bframes=3

Please take a look at bold and underline lines.

How do I set the parameter for x264 to make file can play on my PSP??? (meGUI 0.3.5.0). I know i can use XmediaRecode, but i want to know and I really love meGUI.
There are other big problem bframes=3

Try update your Preset colecttions, all my PSP presets have bframes=0.

Edit: Hello! Sharktooth

[b66pak]

all my PSP presets have bframes=0

there is an error in the presets (they are switched with the iPhone profiles!!!)

PSP supports main profile 3.0 CABAC on, up to 3 refs, up to 16 bframes and NO b pyramid...or...baseline profile up to 2.1 ONLY 480x270(272) resolution
_

[MNCvn]

@b66pak:
PSP supports main profile 3.0 CABAC on, up to 3 refs, up to 16 bframes and NO b pyramid

main profile, level 3, CABAC and 3 refs, I'm sure.
But the bframes, i'm not sure.

There are other big problem bframes=3

Try update your Preset colecttions, all my PSP presets have bframes=0.

Edit: Hello! Sharktooth

I really don't know how to set that parameter. Please see pictures attached below. That's my newest meGUI update today (picture 1). There's only one PSP x264 preset. (picture 1)

And the bframes parameter can't modify. (picture 2)

This is new output file using XmediaRecode with bframes=3 and this file still play on my PSP.

So, the bframes is not the problem. I think that is the "refs" problem because i know the PSP support max "refs" is 3, but meGUI make file with 4. And I can't modify that parameter from the x264 configuration screen.

What should i do???

Thanks.

Do you need the log of audio encode (Nero ACC-LC) and mux (MP4-PSP) jobs?

I use the PSP x264 default configuration profile of meGUI 0.3.5.0 (newest updated).
MNCvn

[Sharktooth]

megui instructed x264 to use 3 refs (--ref 3). what is the problem?

[nurbs]

I think he thinks this
ref P L0: 72.4% 13.8% 10.3% 3.4% 0.1%
means that there are four reference frames, but it doesn't because
1) if you go by the percentages five are used sometimes and
2) the last two are the "free" reference frames that come from the reordering done by weightp and don't take any extra DPB size so they don't count.

edit:
Then again b-pyramid is on in that encode so they won't work on a psp. This would also result in in mediainfo showing four reference frames because b-pyramid implies that.

[MNCvn]

megui instructed x264 to use 3 refs (--ref 3). what is the problem?

Yes, i know that, but the ref of output file is 4.

Please view my last post , post 1412910 (http://forum.doom9.org/showthread.php?p=1412910#post1412910).
Format settings, ReFrames : 4 frames

And this is my problem: i use the old profile of meGUI (old version) make file and play ok on my PSP. After reinstall my Window and meGUI, the newest update just has only one PSP profile. I use it (not modify anything, just let it as default) and can't play the output file on my PSP. That's all. I don't know how to correct it. I think the newest version of meGUI make users less comfortable than the old one.

Does anyone make and succeed playing output file on PSP with new version of meGUI???

By the way, I'm just a normal user. I know a little about encoding. Try to know more.

Thanks.

[nurbs]

As I said, the encode has b-pyramid on, b-pyramid implies 4 refs, the PSP doesn't play files with b-pyramid.

And yes the new PSP profile doesn't work.
The problem is this:
Profile is set to baseline in the codec configuration window, which would disable b-frames. Therefore the b-frame controls don't work. There is a custom command line switch setting profile to main, but --bframes 0 isn't added so at the same time you can't change the b-frames setting but they are still on including pyramid by default.

[Zathor]

there is an error in the presets (they are switched with the iPhone profiles!!!)

PSP supports main profile 3.0 CABAC on, up to 3 refs, up to 16 bframes and NO b pyramid...or...baseline profile up to 2.1 ONLY 480x270(272) resolution
_

Sadly no one noticed the psp profile error in the last three months with the development builds so the wrong values have been applied to the stable build. I am sorry.

I assume this command line is correct?
--profile main --level 3 --ref 3 --bframes 16 --b-pyramid none

I will then push out a new profile set. Are there any other problems regarding the profiles? I count on the community to find errors in the profiles or to provide profiles for new devices.

[nurbs]

Why set --bframes at all? The number is controlled by --preset and --tune anyway not to mention that if somebody switches to a preset slower than the default --b-adapt 2 will kick in which will severely limit encoding speed with 16 b-frames.

[Zathor]

As stated somewhere else I am clearly no x264 profile expert and would like to have the input from someone who knows about the coherences of the settings. The profiles are a part of MeGUI where no programming skills are required so everyone can take part of it.

The problem is that without --bframes the value may be higher than 16 in some scenarios. If selecting placebo + animation it will be 18. It is of course not very likely that the bframes will exceed 16. With the current config menu it is not possible to set a max value so that it will not exceed this value. Instead you have to explicit set it to a value so that the x264 settings will produce a encoding which is supported on the desired target platform. The idea for the "max value" thing has been there for quite some time, but with the announcement of a upcoming --device switch in x264 it has been set to "on hold". But it seams that --device is on hold, too.

[nurbs]

No, none of the presets or tunings will push the number of b-frames or reference frames over 16, just as you can't set them higher manually. That number is a hard limit in x264 which was chosen to make optimizations easier IIRC (static arrays and such).

[Zathor]

If it cannot be set higher than 16 it will make indeed no sense at all to set it static to that value.

[MNCvn]

As I said, the encode has b-pyramid on, b-pyramid implies 4 refs, the PSP doesn't play files with b-pyramid.

And yes the new PSP profile doesn't work.
The problem is this:
Profile is set to baseline in the codec configuration window, which would disable b-frames. Therefore the b-frame controls don't work. There is a custom command line switch setting profile to main, but --bframes 0 isn't added so at the same time you can't change the b-frames setting but they are still on including pyramid by default.

I didn't notice the b-pyramid because it's disable in the configuration window. I don't know it's added by default.

The CABAC is disable too, but the output file is YES. so maybe the custom command line switch setting profile to main and that is result of default main preset and level of x264.

I assume this command line is correct?
Code:

--profile main --level 3 --ref 3 --bframes 16 --b-pyramid none

I will then push out a new profile set. Are there any other problems regarding the profiles? I count on the community to find errors in the profiles or to provide profiles for new devices.

I will give it a try, but i'm not sure about --bframes 16.
If i'm not wrong, the default --bframes value is 3. Mabye I'll let it as default.

Thanks guys.

[MNCvn]

Hi all,

It's done.

This is the commands:

with --bframes = 3 (default) and can play on PSP.
program --crf 20 --profile main --level 3 --ref 3 --b-pyramid none --output "output" "input"
with --bframes set manual = 16 (still can play on PSP).
program --crf 20 --profile main --level 3 --ref 3 --bframes 16 --b-pyramid none --output "output" "input"

Finally, the problem is --b-pyramid parameter. I'll remember that. :thanks: nurbs

I'll test more and post the result here, if anyone want it.

Thanks all.

[heffalump]

Any of you guys run into this? I'm trying to convert a DVD rip into an x264 mp4. Everything goes great, right up until I attempt to process the queue. At this point, the encoding job pops up just long enough for me to see it, before it disappears. The status for the job says "error." No errors are reported in the log.

I'm using Windows 7. I have ATI Catalyst 10.6 installed.

Any help you guys can afford me would be deeply appreciated!

Please try to run the job command line directly (in a cmd outside of megui) and report back.

Absolutely nothing. Executing the command at a command prompt pauses for a moment and then displays the prompt again. There are no messages.

That being said, it doesn't appear that Avisynth is working on my system, any more. I've tried to encode in other formats via MeGUI and they fail with errors related to starting Avisynth. I gave Ripbot a try and it too complained about Avisynth.

I've uninstalled it and re-installed it to no effect.

I recently updated my video drivers to version 10.6 of the Catalyst suite. I didn't have any problems before then. Now, Avisynth (v 2.58) doesn't seem to be functioning. Could that be related?

Update: I uninstalled my video card drivers, ffdshow, and Avisynth. I re-installed Avisynth and things seem to be working, now. If ffdshow doesn't play into Avisynth, then I'm left to assume it had something to do with the Catalyst suite.

[Sharktooth]

probably it had to do with avisynth and broken plugins.
your video drivers do not influence encoding in any ways... except maybe source decoding if you were using dgnvdec (but your card is ati) or directshowsource in your avisynth script

oops... sorry for an "unknown" reason i was thinking your source was MKV... well you miss the MPG (mpeg) splitter, so you better index the file with the File Indexer tool (use either DG or FFMS indexers) and open the index file with the appropriate source filter thru avisynth (megui will automatically create the avs for you thru AVS Script creator)

Hi, congralutions for this wonderful software. Well, i have a problem because megui launch a error, post screenshot:

http://img189.imageshack.us/img189/9836/capturalcg.png

Source video is Bluray of Trinity Blood 1080p. Profile selected is:

Bluray - Very high Quality Bitrate 4365

Somebody help me, thanks

EDIT: Its the last error, invalid argument nal-hrd = --b-pyramid

[Zathor]

Replace every --nal-hrd with --nal-hrd vbr in the custom command line. Or use the new bluray profile that has been installed with 0.3.5.

[MNCvn]

Hi everyone,

I had read many threads in this forum about aspect ratio but, I still confuse it so much. Could someone take me through this???
I want to clearly understand SAR, DAR, and PAR. And how to calculate those attributes. There are many threads in this forum and obviously there are many ways too. But ..... not It's not clearly and not give the same results.

What formula meGUI calculate the global darx and dary???
# Set DAR in encoder to 37 : 20. The following line is for automatic signalling
global MeGUI_darx = 37
global MeGUI_dary = 20

Somebody suggests use default method of meGUI (Clever anamorphic encoding). And, Somebody suggests set the --sar attribute in x264 command line. But the numbers and the formula are so different. Hix...

OK, here's a sample, I has a PAL DVD (720x576) 16:9 and I want convert it to MP4 with 720x480 resolution 16:9 (NTSC). My source must crop some black bar in left, right and bottom. So What should i do with DAR, or SAR to get the NTSC standard??? What formula to calculate it???

Thanks. MNCvn

[Overdrive80]

Replace every --nal-hrd with --nal-hrd vbr in the custom command line. Or use the new bluray profile that has been installed with 0.3.5.

Ok, thanks for your fast reply. I imagine that could be for that reason, because i backup, in other HDD, all profiles that i had modified.

Regards

[jbeale]

For the past year I have generated .mp4 files using the MeGui preset x264:iPod (Classic/Nano/Touch) Standard. This uses the command line:

program --partitions p8x8,b8x8,i4x4 --ref 5 --vbv-bufsize 10000 --vbv-maxrate 10000 --profile baseline --level 3 --output "output" "input"

and I upload the .mp4 files to my web page. The mp4 files are 640x360p, 30fps and play back fine in Firefox using the QuickTime plugin v7.6.2.

I allowed MeGui to update itself a few weeks ago. I now have x264 version 1649 (not sure what it was before). Using the same preset, my .mp4 file will no longer play at all in the QuickTime plugin (just shows me the "Q" logo). The standalone QT player says Error -2041: an invalid sample description was found in the movie (myfilename.mp4)

The file will still play from the local disc using Nero ShowTime. How can I fix this?

EDIT: found problem- I had some strange format set for audio

[Overdrive80]

Hi, i obtein a new error, and this time is for neroaacenc.exe that seems not run. Post screenshot

http://img227.imageshack.us/img227/4980/capturadr.png

[Sharktooth]

That is a warning and not an error. However make sure nero aac encoder/decoder is correctly extracted to your "megui\tools\neroaac" directory (neroaacenc is not re-distributable so you have to manually get it from Nero (http://www.nero.com/eng/downloads-nerodigital-nero-aac-codec.php) website).

[lilhobo]

anyone got preset for quality 700Mb-1Gb outputs? XViD

[Inspector.Gadget]

@Overdrive90, Sharktooth: unless I'm mistaken, that warnng is from the Nero HD Audio decoder called by eac3to, and doesn't have anything to do with AAC encoding. The former requires a licensed copy of Nero 7 to be installed, while the latter requires only copying the freeware encoder to the appropriate directory.

[Sharktooth]

oh.. i overlooked that...

[Sharktooth]

anyone got preset for quality 700Mb-1Gb outputs? XViD
everything depends on the source compressibility, resolution and duration.
presests are made to limit the encoder features (for certain devices for example) or for speed/compression ratio... not for filesize.

[lilhobo]

everything depends on the source compressibility, resolution and duration.
presests are made to limit the encoder features (for certain devices for example) or for speed/compression ratio... not for filesize.

there has got to be some assumptions here:

1. standard dvd source.

2."compressibility, resolution and duration" is limited by the filesize, surely

[Guest]

Make your own profile! It's not rocket science.

[Sharktooth]

1. it stands only for resolution. duration and compressibility can be determined just coz the source is DVD.

2. compressibility has nothing in common with filesize, duration and resolution have. compressibility is how much your preferred encoder can encode your source at a given quality. usually a full quality compression test is done, so you choose how much quality you would like to loose to fit a filesize. if the quality lost is not acceptable then you have to choose a bigger file size OR reduce the resolution (less pixels = less data) and run the CT again... and so on.
experienced ppl may just look at a video and tell how much (more or less) is compressible an what is a safe file size to compress that video to.

however to resume, those 3 parameters are needed for EVERY movie so making a general preset is impossible.

[lilhobo]

Make your own profile! It's not rocket science.

LOL, but I prefer not to reinvent the wheel either.

I been here 8 years, got banned once ;) what happened to all the people who has the time to test all the settings?

it's a matter of PERSONAL knowledge. you have to know what to do for every movie coz every movie is DIFFERENT.
autogk and avi.net are 2 softwares that make AUTOMATED choices but still they do analyze the source... ppl with no knowledge of your source cant "invent" presets from thin air.

@Overdrive90, Sharktooth: unless I'm mistaken, that warnng is from the Nero HD Audio decoder called by eac3to, and doesn't have anything to do with AAC encoding. The former requires a licensed copy of Nero 7 to be installed, while the latter requires only copying the freeware encoder to the appropriate directory.

Yes, if i encode audio this advertise no show it. When i am ripping Bluray it is when show it. I have nero 10, with this no is ok. How could i solve? Thanks

You need to buy a copy of Nero 7 (not sure if they're still available, or be happy with libav decoding - which may be broken for that particular channel order). What is the format of the source audio and what conversion are you attempting? What happens when you run eac3to against the source file and track directly?

I like to AC3 2.0 & TrueHD 5.1 to FLAC from HDStreamExtractor. I hope that be happy with libav XD.

Thanks for your reply. Bye

Does everyone read this? and help me?

I've really searched and read in this forum, but it's still so confuse. I want to write a small program to calculate this, but i' not figure out the formula yet. Hix.

Hi everyone,

I had read many threads in this forum about aspect ratio but, I still confuse it so much. Could someone take me through this???
I want to clearly understand SAR, DAR, and PAR. And how to calculate those attributes. There are many threads in this forum and obviously there are many ways too. But ..... not It's not clearly and not give the same results.

What formula meGUI calculate the global darx and dary???


Somebody suggests use default method of meGUI (Clever anamorphic encoding). And, Somebody suggests set the --sar attribute in x264 command line. But the numbers and the formula are so different. Hix...

OK, here's a sample, I has a PAL DVD (720x576) 16:9 and I want convert it to MP4 with 720x480 resolution 16:9 (NTSC). My source must crop some black bar in left, right and bottom. So What should i do with DAR, or SAR to get the NTSC standard??? What formula to calculate it???

Thanks. MNCvn

Describe the confusion you have with the available material. Nobody wants to just repeat it all with the hope that it won't also confuse you.

http://en.wikipedia.org/wiki/Pixel_aspect_ratio (PAR and SAR are the same. PAR=pixel aspect ratio, SAR=sample aspect ratio, 2 different names for the same thing... SAR may also mean Storage Aspect Ratio... in that case it's not the same)

Yes, I known. But at least, there must have some source really clear.

Thanks Sharktooth. I forgot wiki, just looked for in this forum. Hix
