MeGUI: General Questions and Troubleshooting Thread

[nurbs]

What do tunings do exactly? And what is this slider thing?
"x264 --fullhelp" will show you the description of the presets and tunings. Other command line options are applied after the presets and tunings and thus override them. Level flag restricts presets and tunings (e.g. by lowering number of reference frames), but not custom options.

There are also plenty of threads in the AVC subforum.

[Dark Shikari]

I think any value of --weightp that is not 0 will produce visual artifacts in CoreAVC < 2.0. :\--weightp 1 will work fine.

Newbie here coming from using Handbrake and Staxrip and having frustrations with them so moved on to MeGui. I just want simple. In Handbrake and Staxrip I just had to set a few settings. Mainly I focused on cRF (setting it at 20 for very high quality). In the one-click encoding on MeGui (which appears to be the closest equivalent to these other two programs), I don't see a way to set -cRF? How do I set it?

Thanks!

I'm using MeGUI 0.3.1.1056 with Nero Digital AAC Encoder 1.3.3.0.

Is it recommended/allowed to manually update Nero encoder to the latest version (1.5.1.0)?
Is MeGUI compatible with this latest version of Nero encoder?

Thanx in advance.

[Alf Bundy]

Well, I don't know with the old rev 1056.
But I've just downloaded the latest NeroAACenc (http://www.nero.com/eng/downloads-nerodigital-nero-aac-codec.php) and it works fine with the latest Megui 0.3.1.1059 (http://85.230.118.136/showthread.php?t=151159) ...

[tebasuna51]

NeroAacEncoder v1.5.1.0 have the same parameters than precedent version, then work without problems with MeGUI, BeHappy, eac3to, BeLight, ...

[consultant]

I'm wondering if MeGui is capable of this and if so, where is the documentation that explains exactly how to do it?

I've got a whole bunch of music video DVDs already ripped into chapter VOB files. I want to queue them all up to be transcoded. I want them to all be transcoded using the same encoder setting which produced a hiqh quality file that is about 1/4th the size of the VOB (I've found this equates in other programs to a cRF=10, Speed=Medium). I want meGui to automatically encode the best audio track, so if there is a stereo track and a 5.1 track, I want it to include the 5.1 track not the stereo track. I want to just load a profile and point at all the VOBs to add to the queue and hit start and let it chug away for the day.

Is this possible? I think the audio encode choice may be the sticking point. My guess is I can only do this one DVD at a time as the audio tracks vary from DVD to DVD so I assume I need to add all the VOBs to the queue for one DVD, set the audio settings and then do the same for the next DVD?

yes, it's possible.

here's roughly how, i dunno if there's documentation on doing exactly what you're doing.
http://mewiki.project357.com/wiki/MeGUI/Basic_DVD_Ripping_Guide

[consultant]

I'll look at that documentation but it says in bold:

It does not cover:

* Using any of the automated features of MeGUI for video encoding.

I want to just load a profile I created with all the settings, select all the VOBs, and hit "start"

[quantum5uicid3]

try a different program

[pdexdee]

i use winxp sp3 but won't work and latest neroaac

[dolphinjet]

Merry x'mas everyone!

Recently,
I noted a problem with build 1056 (after a long time without encoding)

The megui interface become unresponsive immediately after starting the queue,
sometimes it will become responsive again after finishing the first task,
sometimes it will not even start the first task,
sometimes it crashes firefox v3.5.6 instead of itself (when megui is responsive, the two apps seems to be fighting with each other)

I think I should modify to a simpler description.

megui would crash the topmost application.

I rolled back windows to a earlier installation but the problem still persists.

I am using winXP SP3
I have re-install megui for a few times already. I've also tested build 1058 but got errors so reverted back to stable build.

megui settings:
priority low
disabled open progress window

[pdexdee]

as first: Merry x'mas to all people here!
what means:
when i put file says:Unable to render the file. You probably don't have the correct filters installed ....
but when i put other file first create dgindex and all other work correct,what u suggest to me?
i have version 3.1.1051 installed.
would be good to fine version with all profiles!?
i have windows xp sp3 also k lite codec full pack!

[ariefjuga]

just want to ask why my megui say there is no update available. But, in above i see there is people who already have the latest version of megui. My megui still 3.1.1051. Is it because there is not yet any stable upgrade version?

[XhmikosR]

@ariefjuga: Use this (http://forum.doom9.org/showthread.php?t=151159) build.

[ariefjuga]

@ariefjuga: Use this (http://forum.doom9.org/showthread.php?t=151159) build.

MeGUI: Patched Build? :confused:

Is it some kind of new MeGUI?

[XhmikosR]

It's the same old MeGUI except that it should work much better since Zathor has fixed a lot of bugs. Read through that topic for more details.

[ariefjuga]

do i have to uninstall my old megui first?

[rapscallion]

do i have to uninstall my old megui first?
No, you can install to a different dir and then run either ver.

[FlezZ]

I don't know if this is a bug but it's definitely very weird behaviour.

I set a default output directory in the settings and then enqueued 2 separate passes of encodings and started the queue.
Both of processes then started at once. However, if I removed the default directory, the processes start in sequence.

Anyone else have this?

Edit:

Ok, I don't know if these things are actually connected to each other, but I am still having the problem with the processes starting at once.
There's an error for the second encoding process in the queue:

-[Error] An error occurred: x264 [error]: ratecontrol_init: can't open stats file
-[Error] An error occurred: x264 [error]: x264_encoder_open failed

This is obviously the result of the problem, not the cause, because the 2 encoding processes start at once, and the second pass encode cant open the stats file as the first one is already using it.

Which build of MeGUI do you use?

[FlezZ]

Up to this point, the newest I believe: 0.3.1.1060

[Dogway]

Ive been having problems with megui since I updated the driver of the chipset on my laptop (I was having blue screens). It's a Mobile PM45 Express Chipset.
Im not totally sure that's the problem, the fact is I dont see why MeGUI should have a problem with this. I already re-installed and updated to the latest version.

I attach a picture with the problem (the stats are not showing):

sorry about that.

[LigH]

Compare "BUKOWSKİ" with "BUKOWSKY" ... seems that some system function tried to substitute a regional Unicode character with the nearest possible ANSI character.

Avoid accented characters in file and directory names. I believe the "İ" is the problem. (Is that turkish?)

[tebasuna51]

Seems a bug with chars:

MeGUI version 0.3.1.1056

When presented with NTSC DVD 4:3 video, MeGUI wants to use a SAR value of 28481:31250 with x264. I do not know how MeGUI comes up with that value, as that would translate to 656.20224 instead of 640. It seems as if it is working with 704 instead of 720. Even then the SAR would be 10:11, to get exactly to the required 640. For 720x480, the SAR should be 8:9.

I'm not cropping the video.

Any idea why the SAR is wrong?

Thanks

[MrVideo]

I'm guessing characters that do not have the special emphasis above them.

I'm not cropping the video.

Any idea why the SAR is wrong?

There are a few defined constants for DAR in MeGUI:
ITU16x9PAL = 1.823361
ITU4x3PAL = 1.367521
ITU16x9NTSC = 1.822784
ITU4x3NTSC = 1.367088

So your 4:3 NTSC source has a DAR value of 1.367088.

SAR will be calculated as DAR * vres / hres and that's 28481:31250 in this case.

But I am only repeating the internal code - I do not understand DAR and SAR calculations fully. It would be great if someone can point me to a site where this particullary problem is described in more detail and tell me which value is correct in this case - the one from MeGUI or MrVideo.

[stax76]

You are lucky you are german so you can read Brother John's Encodingwissen. His site and support helped me a lot building image related things in StaxRip.

[MrVideo]

So your 4:3 NTSC source has a DAR value of 1.367088.

SAR will be calculated as DAR * vres / hres and that's 28481:31250 in this case.

Is that: (DAR * vres) / hres
or: DAR * (vres / hres)

I know, they're both the same :cool:

But I am only repeating the internal code - I do not understand DAR and SAR calculations fully. It would be great if someone can point me to a site where this particullary problem is described in more detail and tell me which value is correct in this case - the one from MeGUI or MrVideo.

DAR is the Display Aspect Ratio

I forget exactly what SAR abbreviates from.

In the case of NTSC and PAL, the aspect ratios are 4:3 (1.333333) or 16:9 (1.777777). They are not what is listed. With your formula, it makes sense that the SAR comes out wrong.

Filling in the formula with the correct values results in: 1.333333 * 480 / 720 = 639.99984 / 720 = .888888666 = 8/9

The better, and more accurate way to get the SAR is not to do the math on the 4:3 first but to do: ((vres / 3) * 4) / hres

That will result in exactly .888888888888, or 8/9

Make sense?

[Mizzle]

Hi, I just converted my very first avi file to an mkv to test it out on Youtube.
Are there any recommended settings for the best quality or anything to get in HD there...?
(btw, atm I'm getting the 'An error occurred...' message for that video aswell)

Does anyone know how I can make megui run on linux?

[nurbs]

Just bumping my question. Does anybody know how to make megui show statistics while encoding? Im using the last x264 build.
x264 doesn't show any statistics during encoding apart from bitrate, which MeGUI indicates with the projected filesize, and the encoding speed, which MeGUI already shows.

[Dogway]

x264 doesn't show any statistics during encoding apart from bitrate, which MeGUI indicates with the projected filesize, and the encoding speed, which MeGUI already shows.

Yes, that's why I post here, MeGUI doesn't show projected filesize, nor encoding speed.

[Alf Bundy]

Yes it does ... Unless you unchecked "open progress window" in Options -> Settings.

[Dogway]

http://img5.imageshack.us/img5/860/megui.gif

I posted this on previous page showing the problem. Everything is blank.

[Zathor]

Do you have the problem with other tools in MeGUI as well (like converting an audio file)?

Please post the log and execute the commandline in a cmd manually. Do you see a progress there?

[Dogway]

Yes, audio is ok. The log is posted in page 259, and yes command line shows progress, eta, kbps, everything.

Now I dont know if the problem is x264, or MeGui which isn't capable of translating the (last build) x264 statistics.

[Zephyr_Truesdale]

I'm having a problem encoding an old video with x264 and I haven't had a problem before but I think its something that the current version 0.3.1.1061 that's the problem.

[nurbs]

Will you tell us what the problem is or do we have to guess?

[Nikolausr]

Is there a way to get logs be more informative?
