MeGUI: General Questions and Troubleshooting Thread

[Drake008@]

Can someone tell me why the video is streched when it finds 16:9 format? I mean the picture doesn't fit and looks like crap.

[zora]

I always get the error
"unknown style found: "Copy of DefaultSE" changed to "Default"!"
after selecting an avisynth script. In the encoding process it too pops up. It is so annoying. does anyone know a fix for this?

Edit: Here is a pic
http://i40.tinypic.com/1628r6f.jpg
after I click cancel it still pops up
Does someone know a solution for this?
Even a fresh installation of megui doesn't solve this.
I've tried everything.

another one...

thanks
Do you have virtual memory enabled? Mine was disabled and I was getting some crashes with megui. Now, I have enabled it and none till now.

Just FYI on interface problem in Vista 64. I know you don't support it, but I have lost Gui buttons in the past but was able to get around it. This one is a killer...

I lost the Avisynth save button before, but was about to work around. Have not had the Aspect ratio button either. Not sure why this is happening, just thought you should know. I went back to core 0.3.0.3004 to get the DV2 Creator fixed, so it was lost with a change since then.

Hello.

I ripped Transformer Blu-Ray and encoded it to 1080p no problem.

But then I decided I wanted it to be 720p to save some space on HD. I was too lazy to re rip the Blu-Ray, so I decided to use the 1080p source, but something very weird happened. Instead of desire 4000 bitrate, it came up with 300 average bitrate at end!

I used x264: Standalone-Blu-ray, the only thing I changed was the bitrate from 8000 to 4000.

I'm thinking that its x264 bug or what?

Thanks for help.

PS Just noticed there's new version of x264, will download it and try 1st pass of 2nd pass and see what's output's stats is.

[Seraphic-]

In the Nero ACC configuration, is "improve accuracy using 32 bit & flow computations" recommended to be enabled or disabled?
Is turning it on or off based on the encoder configuration used and file input?
(I.E - LC vs HE and 128 kbit/s vs 256 kbit/s or 16bps vs 24bps with 44.1kHz vs 48kHz).
Or should it remain enabled regardless? Thanks.

[SacredCultivator]

Hmm for some reason when I encode audio to .mp4 using FAAC, the audio comes out very "static-y/noisey", in the past this never happened, and now I am useing Nero as the alternative.

Anyone know why this happens? And when using the Nero encoder, how does the VBR work? As it is b decimal, ex. .5, if on the FAAC I used 90, would that be equivalent to .9? NOt too sure.

Thanks.

OH MY GOODNESS.

It was ArcSoft TotalMedia Theater's fault!!! I was using it to watch my ripped Blu-Ray, but it wasn't until 3 or 4 days after I started to using MeGUI again. Look like ArcSoft's codec was having some conflict with ffdshow. After uninstalling ArcSoft program, the bitrate came out right!

Downside, I probably would have to find new Blu-Ray player on my computer. :mad:

Hope this help some people out there.

Sorry, I can't reproduce your problem (v0.3.1.1009).
BTW, NeroAacEnc is now better encoder than Faac, use always Nero.
And when using the Nero encoder, how does the VBR work? As it is b decimal, ex. .5, if on the FAAC I used 90, would that be equivalent to .9?
Nope.
I recommend you use this ranges:
<.31 -> to play with low quality audio equipment.
.31-.35 ->to transcode ac3/dts with minimal lose of quality
.36-.5 ->to compress lossless sources, good quality
>.5 ->to compress lossless sources until insane quality

[SacredCultivator]

^Thanks.

So then I don't know if it's comparable, but let's say if for .mp3 I use 128kbps (CBR) what would be the rough equivalent in VBR for nero? and same for if it were 192kbps?

Thanks again.

hi,

i try to downmix a 6ch ac3 track to stereo aac and i get a 3ch aac!

L.E. Actually the source is 3ch ac3!

Format : AC-3
Format/Info : Audio Coding 3
Codec ID : A_AC3
Duration : 1h 36mn
Bit rate mode : Constant
Bit rate : 640 Kbps
Channel(s) : 3 channels
Channel positions : L C R
Sampling rate : 48.0 KHz

L.E.2 any sugestions how to downmix 3ch to stereo?
_

[Kurtnoise]

you can't do that with MeGUI...

[Snowknight26]

Selecting a FLAC track in the bitrate calculator causes a fatal error of Value cannot be null. Funny thing is though, it fills in the bitrate field because the mediainfo wrapper supports FLACs.

How about that DTS bitrate issue, too?

[tebasuna51]

So then I don't know if it's comparable, but let's say if for .mp3 I use 128kbps (CBR) what would be the rough equivalent in VBR for nero? and same for if it were 192kbps?

Please :search:
There are many comparatives between audio codecs and in this thread is off topic.

Maybe 0.3 and 0.5

L.E.2 any sugestions how to downmix 3ch to stereo?

You can create an sample.avs file (using Notepad) with this line:
NicAc3Source("F:\x264\Vicky_Cristina_Barcelona_688p_ac3.ac3", 2).Normalize()
and open the sample.avs in MeGUI (Audio Input) instead the .ac3

NicAudio can downmix 3-6 channels to 2 channels internally.

[b66pak]

@tebasuna51 thanks a lot...

@Kurtnoise13 handling exceptions and errors is a VERY important part of a program! if megui cant handle anything but 6ch>>2ch a warning must be done to prevent losing time and unwanted results...
_

[Kurtnoise]

There are errors/exceptions handling. Just tell me why should I raise errors notify when all is fine...

[Kurtnoise]

tell me how you open flac files in bitrate calculator. This kind of file is not allowed. Embedded in Ogg container ?

How about that DTS bitrate issue, too?
should be ok in the next release...

[Snowknight26]

tell me how you open flac files in bitrate calculator. This kind of file is not allowed. Embedded in Ogg container ?

Type * in the file name textbox, select .flac file. If it's not allowed, it shouldn't fill in the bitrate field afterwards. ;)

[Kurtnoise]

Type * in the file name textbox,
which one ? I'm lost...

[Snowknight26]

In the standard Windows Open File Dialog when you click Select audio in the bitrate calculator.

this is for windows 7,

MEGUI works fine, as does x264 - but was wondering about UAC. why does MEGUI trigger it? my problem is, i turned UAC off in win 7 for megui and doing so disabled the sidebar

[ankurs]

well i've been trying to make and open a d2v after megui got updated and seemingly its giving me a wierd error !

i just made the d2v again and still to no avail , also agony is vdub crashes as well no matter what ever versions i tried already without any reason ..

also i've already uninstalled and reinstalled avisynth to the latest RC version , also , what is more wierd is that the same d2v is working fine in gknot !

http://i43.tinypic.com/5kk294.jpg

any help ?

xp sp3 upto the latest update and .net fw it is !

[b66pak]

as you can see in the log i selected "downmix multichannel to stereo" and i get a 3 channel audio which is far from fine...so it was better to get a warning about this...or you can change "downmix multichannel to stereo" to "downmix 5.1 to stereo" to avoid any confusions...
_

[ankurs]

now its confirmed , the error i'm facing is happening on my other pc as well after updating megui .. probably some screw up in the update package ?

everything worked fine on both pc's before updating , i checked the same d2v before updating on the pc and it worked fine and now after updating its giving me the same error .. devs ?

[b66pak]

sometimes after encoding in a .mp4 container i get "bad public atom error" from QT...megui and its components is up to date (0.3.1.1009)...here is the log:

as you can see first i encoded the audio to .m4a ...second i encoded the video to .mp4 and finally do the mux.

my_audio.m4a play fine with QT
my_video.mp4 "bad public atom error" with QT
my_video-muxed.mp4 "bad public atom error" with QT

first i think it was a mp4box muxing error so i remuxed my_audio.m4a and my_video.mp4 with an older version but the result was the same...

i think the x264 encoder broke the atom and the mp4box forward it to the final mux...

the solution is to demux to raw and remux again...

[Kurtnoise]

as you can see in the log i selected "downmix multichannel to stereo" and i get a 3 channel audio which is far from fine...so it was better to get a warning about this...or you can change "downmix multichannel to stereo" to "downmix 5.1 to stereo" to avoid any confusions...
_
from the log...

6<=Audiochannels(last)?x_stereoad747990273e4b049a3a6e8c0750cc10(ConvertAudioToFloat(last)):last

so for me, it's multichannel (6 or less).

[Kurtnoise]

now its confirmed , the error i'm facing is happening on my other pc as well after updating megui .. probably some screw up in the update package ?

everything worked fine on both pc's before updating , i checked the same d2v before updating on the pc and it worked fine and now after updating its giving me the same error .. devs ?
looks like you have not dgdecode.dll in the right folder...

[Kurtnoise]

this is for windows 7,

MEGUI works fine, as does x264 - but was wondering about UAC. why does MEGUI trigger it?
it's required for packages installation (w/ or w/o the auto-updater...)

[ankurs]

looks like you have not dgdecode.dll in the right folder...

it is there in the plugins and IN ALL other folders it is supposed to be in , still the same problem :scared:

[Kurtnoise]

well...recreate your d2v file then with all tools updated.

[ankurs]

still doesnt work :s ..

what's more wierd is why is'nt vdub working ?

[Fishman0919]

I can't seem to get MeGUI to start on a new install of WIN XP sp3. Does MeGUI work with Win XP?

[xxx666yyy777]

I am trying to use the One-Click Encoder. However, after generating the .d2v file, I receive an error message that the dimensions specified in the rsulting .avs file are invalid. APparently (based on the log below) this is caused by the Autocrop functionality. Is there a way to disable Autocrop, when using the One-Click-Encoder?

Does MeGUI work with Win XP? Yes if you install .NET 2.0 or higher ;)

[Fishman0919]

Yes if you install .NET 2.0 or higher ;)

It is and completely updated.

I uninstalled MeGUI and rebooted, reinstalled and it worked fine... sorry. Should have tried that first. :o

[marioman]

Hey I seem to be having an issue with MeGUI, I can't seem to start it for some strange reason. It says: "MeGUI encountered a fatal error and may not be able to proceed. Reason: Font 'Tahoma' does not support style 'Regular'."

I've searched for about 2 hours trying to fix this but I cannot find even 1 instance on the net of this happening.

I am running Vista Ultimate x64 if that matters.

[starmanj]

Latest Megui has a problem with one-click. When I drag a .vob to encode, it names the file after the .vob's parent directory by default. So naturally other files have a filename conflict, as they are all called the same filename. The obvious default filename should be named after the *original file*, right? With the new container's suffix.

BUG?

[Snowknight26]

DTS bitrate issue is still there even though it's supposedly been fixed.

Hi:

I am having trouble again trying to process files with one click encoder.

I am trying to avoid cropping, so I've generated an One click profile that uses an avisynth profile where I removed the <crop> line. I was just supposing that this way One Click Encoder would not crop video, and what happens is that video is not cropped, but it is incorrectly AR signalled as if it were cropped.

In the log, you'll see:

original 720x576, ar 1,818
Autocrop: top 70, bottom 70
output res: 720x432, darx=224, dary=93 (ar=2,408)
sar passed on to x264=896/465=1,927
frame size=720x576 (it is not autocropped)

Second, although I am now keeping all original audio tracks so there are not differences in the audio stream number in the .vob and the .ifo file, if the audio stream is not the first one, the d2v step extracts correctly the audio, but then one click fails to find it and no muxing occurs

Log:
---[Warning] OneClick postprocessor
----[Warning] Couldn't find audio file for track ::3::. Skipping track.

Track T83 3_2ch 384Kbps DELAY -16ms.ac3 is created and It is present in the movie folder (it is the working folder)

Thanks for the help :thanks:

[ricky man]

i installed vista x64, CCCP or vista Codec x64, FFDshow x64 and MeGui. when i just to encode m2ts file. It tell me that Directshow tell me that " Unable to render" or Please installed the correct filter or codec.

can anyone please help me to fix this problem?

[flebber]

An observation, when using the avs svript creator in megui and choose input file, flv files do not show as supported files. However, I changed the setting to all files and imported an flv file into megui and it worked fine audio and video encoded and muxed fine.

So why isn;t flv a supported file if megui does it with ease?

[CHerron]

Hi,

For quite a while instead of using megui to get the sar ive added it to the custom command line in x264 config.

This has worked fine until the last few versions. i've noticed that megui is adding a second --sar 1:1 to the command line as well as my --sar 64/45.

This of course is overriding my custom sar.

Is there anyway to stop megui from auto adding an sar to the command line?

Thanx

[Sharktooth]

what preset are you using?
however, it may seems obvious but check and ensure there is no --sar 1:1 specified in the custom commandline options.

Hello

I have been reading the forum for a few months now and this is my first post. Hope it is in the right place (it doesn't just relate to MeGUI).

OK. So I have read guides on doom9, Afterdawn and Videohelp about using MeGUI to encode to H264 (including the wiki) plus general articles on square pixels, aspect ratios and 'Video Basics' at these two great sites...

http://lipas.uwasa.fi/~f76998/
http://lurkertech.com/

The problem is I think I have just read too much too soon and completely confused myself.

This refers to encoding h264 in MeGUI

Question 1) If I want maintain the original resolution of a 4:3 DVD source with non-square pixels should I use the clever anamorphic setting but select 4:3? My assumption is that the image still needs to be stretched vertically to make 4:3 image. 720x576 becomes 768x576.

Question 2) How can I quickly determine the aspect ratio of a DVD image (after cropping) and does this matter?

At the moment I would capture a frame of a vob/mpg, open this in an image editor, crop any black borders then read the dimension properties. I divide these pixels to find the AR of the image. Can this method be trusted, what if the player is adjusting the image incorrectly? Can this analysis be done in MeGUI with AVS script creator? If it can this would be much quicker! How about something like AVsP

The reason I ask is because people often say check the OAR on Imdb or the DVD case but how do we know a DVD has been given the right AR (image only)? it may be slightly off with too much black bars etc? What if a silent film was originally 1.20 or you have a pre 1953 film with a AR of 1.37? I would like to know whether the DVD has simply been mastered to 1.33 or correct borders have been applied. This is also true for tricky ARs like 1.66 which DVD publishers often seem to get wrong.

For example if I load a d2v file into AVS Script Creator within MeGUI and select clever anamorphic and crop to the edges is there a way I can read the AR of that actual framing and adjust accordingly so that it is maintained? Maybe I would need to add borders myself or crop a little for mod16 dimensions but I want to maintain that framing.

For example

If you select the input DAR as 4:3 (ITU....) select anamorphic and crop the image the resulting darx / dary should give you 1.33333. If it doesn't it means the image was not mastered to ITU added border spec. Yes?

From here I can either manually input a DAR of 1.3333 but I can only do this if I know my above cropping equals 1.3333 if it is any other figure I am going to change the AR from the DVD image or is this wrong?

My point is that if a DVD gets the AR / border slightly wrong we still have to assume the picture dimensions are correct (face shape) even if the cropping isn't and by 'correcting' it we are skewing the dar dimensions.

Am I simply worryring about nothing?

Thanks for your time.

I have thought about this some more and realised I could work out the image AR after cropping by taking into account how many pixels have been cropped. I noticed some of the auto help pop-ups in gspot spoke about SAR, PAR and DAR.

So, if I had a 4:3 MPEG-2 PS with a resolution of 720x576 I can work out what Gspot calls the SAR or Storage Aspect Ratio.

720/576 = 1.25:1

We know the DVDs Display Aspect Ratio (DAR) without cropping is going to be 4:3 or 1.33:1

Gspot says SAR x PAR [Pixel Aspect Ratio] = DAR

For an MPEG-2 PS it just gave me a PAR of 16/15 or 1.067:1 but this could have been worked out by dividing DAR by SAR though you wouldn't get the nice equation. With this I can work out the DAR after cropping. I crop the image in AVS Script Creator. I see I have taken 2px left, 10px top, 2px right and 10px to the bottom. If this is subtracted from the original resolution I get 716x556. Using the equation...

SAR x PAR = DAR

(716/556) x (16/15) = 1.373

This tells me the image on the DVD has been maintained to the films original ratio of 1.37:1

So if this is correct how come http://lipas.uwasa.fi/~f76998/video/conversion/#conversion_table gives the PAR for 720*576 video as 128/117?

Still confused but I think I am making progress.

Also can I simply put 1.373 into the AVS Script creator DAR field or is it recommeneded to manually add the SAR too? Where do you add this? To the AVS or to a script for x264?

Hope someone can help

Thanks

[Kurtnoise]

all SAR/PAR calculation is done by megui in internal...No need to specify anything in the encoder settings. but don't forget to check "Clever anamorphic encoding". The DAR from your source should be found automatically.

[Kurtnoise]

An observation, when using the avs svript creator in megui and choose input file, flv files do not show as supported files. However, I changed the setting to all files and imported an flv file into megui and it worked fine audio and video encoded and muxed fine.

So why isn;t flv a supported file if megui does it with ease?
because flv is not listed in the "supported files" list...:)

Thanks for the reply.

Do you mean don't bother changing the ITU 4:3 selection or that once I have worked out the DAR after cropping and put it in the box MeGUI will work out the rest? i.e work out the PAR from the DAR I have input and the aspect ratio of the original resolution.

Is this guide wrong?...

http://www.afterdawn.com/guides/archive/dvd_to_avc_megui_part_2_page_2.cfm

"The Input DAR will tell you whether the video is a PAL or NTSC source, as well as whether it's fullscreen (4:3) or widescreen (16:9). You may notice that the decimal notation for the aspect ratio doesn't match either fullscreen or widescreen (such as 1.822784 for NTSC 16:9 instead of 1.78). This reflects the area of the frame that's visible on your TV, with the extra left and right borders cropped to match the ITU-Rec.601 standard.

If you prefer to set the AR to exactly 16:9 or 4:3 you can do that by using the Select AR... option, which will open the Custom AR dialog so you can set the value manually. For an AR of 4:3 use 1.333. For 16:9 it would be 1.778 instead.

About Aspect Ratios
Although MeGUI's AR figures reflect the correct calculations using the official ITU recommendation DVDs are all supposed to follow, there's no guarantee that this will be the case. In fact all the widescreen (NTSC) DVD's I've encoded needed this set to a custom AR of 1.778 in order to achieve the correct AR (as listed on the DVD case) after cropping. Fullscreen DVDs, such as TV shows, seem to be less consistent, with some strictly following the same ITU figures MeGUI does and others assuming the entire frame to be part of the 4:3 image. In the final section of the guide on The Edit Tab we'll look at how to doublecheck the output AR."

Later in the guide it says if you divide darx / dary this gives the final DAR? If this is wrong why shouldn't you change it?

Also is it correct to assume that when anamorphic is selected it will never change the PAR and when it isn't any resize will change the PAR to 1:1?

What are the rules for when MeGUI will and won't change PAR.

Thanks again

[mojibake]

Hello again. I did some tests and understand that the DAR input is the DAR before cropping. I never got that! Sorry.

I did a hypothetical crop of a 4:3 image to 650x576 which should give a AR of 1.20:1 (I wasn't worrying about mod16 at this point).

When I kept the input as 4:3 (ITU) it gave a final DAR of 1.23:1
When I gave the input as 1.33 it gave a final DAR of 1.20:1

So why not put the input in as 1.33 rather than 4:3 (ITU)?

I need to read up on why this ITU input was made.

EDIT:

OK. I did a bit more reading and have worked out why the ITU ratio is used.

I'll write it hear in case anyone who is confused like I was (still am) needs it explained.

look here http://lipas.uwasa.fi/~f76998/video/conversion/#conversion_table

the 'active' picture area of a 720x576 is officially supposed to be 702x576. If you use the equation I wrote in a previous post but treat 702x576 as the starting point and 720x576 as the target the result is the ITU ratio seen in meGUI.

DAR / 'Active' SAR = PAR (4/3) / (702/576) = 1.094017

'resolution' SAR x PAR = DAR (720/576) x 1.094071 = 1.36752125 rather than 1.333

if you do the same but for 16/9 you get 1.823361 rather than 1.777778

Can someone please confirm for me that you can get a DVD with an active picture area of 720x576 and these are the DVDs that do not need the ITU ratio as the image fills up to the edge using 720px rather than 702px. I always thought (ever since reading the referenced article) that all 720x576 digital video had an active area of 702. Even though I always understood px as being visual I just assumed you saw 720 listed because of some strange science/maths and there were only 702px maybe caused by non square px and anamorphic stretch which I didn't understand.

If this is true I might write something about it as all the guides brush over it.
