MeGUI: General Questions and Troubleshooting Thread

[tebasuna51]

And what about external programs?
To encode to AAC you have enough with:

Or the best QAAC:

I never use FDK-AAC

I'm direct adding audio in MeGUI audio input without any file indexer or Directshowsource.

I also added the eac3 to MeGUI audio input tab.
Encoder Settings: Nero-AAC
Config: (like image attached)
Without previous indexer but with decoder LWLibavAudioSource like I say in previous post.

The script generated is in my log attached:
LoadPlugin("D:\Programa\megui\tools\lsmash\LSMASHSource.dll")
LWLibavAudioSource("D:\Test\AudioN\eac3\6chan.eac3")

Wrong? No, but my choice is select quality instead size.

As more and more people (such as myself) are venturing into the wonderful world of MeGUI and AVC codecs, I find myself running into little problems here and there. Being that it is best not to hijack the MeGUI Bug-Report Thread (http://forum.doom9.org/showthread.php?t=105160), it might be time to start up a general questions/troubleshooting/help thread where those with MeGUI experience can lend a hand and noobs can help each other struggle through the learning process. This way us noobs can keep out of the developers hair, and let them develop, not field each persons 20 questions and simple-settings-screw-ups.

______________________________________________________________________________________

So, to kick it all off, I just ran an encode of "The Island" through MeGUI. I used the audio, video, and muxing tool to get a MP4 file. Sounds great except the audio was out of sync :( So I'm not sure what happened. I think it might be a problem with my d2v rip or something, because I ran the movie a few days ago (video only) and tried to mux using YAMB with a AC3->AAC BeLight converted file, and have the same problems. I've never heard of DGIndex screw ups though. So is that the problem, or is it in the AC3->AAC conversion, or the MP4 muxing? Either way has anyone heard of audio sync problems with MeGUI using the auto-encode mode?

And more to the point, does anyone know how best to figure out how much I need to delay the audio? At this point, it might be best to demux the tracks and try to remux them with delay. I don't know, anyone got any ideas?

I don't think it's the audio problem. You don't have to convert AC3 to AAC. Instead, try a video converter tool with "Video/Audio sync" feature to 1-click synchronize the video and audio tracks.

Hello. I'm trying to check out MeGUI x64 but upon simply trying to index an .mkv receive the error message:

Cannot load a 32 bit DLL in 64 bit Avisynth: 'Path.../AviSynth 2.5/Plugins/AddGrainC.dll'.

which is alphabetically the first plugin in my AviSynth Plugins folder. Is there a trick for pointing MeGUI x64 to the Plugins64 folder? Thanks for any help.

How to improve color in MeGUI?

[LouieChuckyMerry]

Hello. I'm trying to get 64 bit MeGUI-AviSynth+ running properly but am experiencing technical difficulties, so here I am looking for help from the really³ smart people who frequent this thread :) . I'm to the point where I can index and queue my script but when I attempt to run it x264 crashes with the error message "H.264 (MPEG-4 AVC) encoder has stopped working". Here's the error log:

I can read the log, but deciphering it is another matter all together ;) . Any help is much appreciated.

[HOB]

My most recent version of MeGUI Beta is 2908, I haven't seen any updates for some time. Is it still being actively developed or is it on hold?

BTW...this is my favorite goto program for working on old videos I have that need fine tuning.

[Barough]

Maybe Zathor have taken some time off. The last post he made was on 15th March 2019, 12:09.

[HOB]

Thanks for the reply Barough...well deserved time off if that's the case.

[Xor]

Use Megui 2908 X64 please help me to reduce NOISE old movie bluray

Thanks a lot

[tebasuna51]

@Xor

To use MeGUI <denoise> filters go to Filters tab like the image.

There are many other denoiser filters in AviSynth but you need load the necesary plugins and add the functions manually in Script tab.

[Xor]

Thanks @tebasuna51

[LouieChuckyMerry]

Hello. I finally upgraded to MeGUI-AviSynth+ 64 bit but have a final (ha ha) MeGUI question. Every time I open the 64 bit (latest, developmental server) version, MeGUI downloads almost 100MB of .dll's: api-ms-win-core..., mfc..., etc. because every time I close MeGUI 64 bit all of the .dll's are deleted. Any ideas how to get MeGUI 64 bit to simply keep all these .dll's upon closing? Thanks for any help :) .

What is New Update Servers of MeGUI My MeGUI Unable to Update

[imsrk48]

@Zathor Sir Please Tell Which is New Update Servers?

[LouieChuckyMerry]

Happy Saturday! and another question :) . When using QAAC with the latest developmental build of x64 MeGUI to downmix audio in .mkv's, the output file has no language tag (it's "undetermined") even if the audio language is properly tagged in the .mkv itself. Is there any way--the Extra/Custom Command Line, maybe?--to get the output file to keep the language tag? Thanks for any help.

P.S.--Any answer for my recent question about the x64 version of MeGUI downloading ~100MB of .dll's every time it's opened?

[Zetti]

Are you sure about the dlls, i think it just copying from tools\redist every time and then closing MeGUI then the dlls getting deleted again.

[LouieChuckyMerry]

Thank you for teaching me something, Zetti :thanks: . Now, any idea about keeping the language tag :D .

[nandoom]

Hi,

I haven't seen any updates since the last 2908 or any component update for a while now.

Is Zathor still around here?

Thanks

[tebasuna51]

Last Zathor post 15th March 2019, 12:09

Last MeGUI components update 19/05/2019 (ffmpeg 4.1.3, MkvMerge 34.0, Qaac 2.68)

[nandoom]

Yeah. Wondering if he is gone for good? and no one else to support this tool anymore?

[locotus]

Yeah. Wondering if he is gone for good? and no one else to support this tool anymore?

I hope Zathor is just making his and his family living, he's been
giving a very continous and dedicated support to Megui for some years, so I prefer to think that if he'd decided to leave Megui he himself would say so.

Besides, Megui and it's dependencias are quite stable even if
there's no update recently.

[Octo-puss]

Seems like MeGUI is crashing when it encounters files with specific regional characters, in this case czech.
It repeatedly crashed to desktop on a file that has "á" and "ň" chars in the name.

[stax76]

I don't know in detail how Windows behaves and how MeGUI works. The codepage which Czech is using Windows-1250 has these characters covered however so theoretically a GUI such as MeGUI which uses ANSI only tools such as AviSynth can work with such characters. One thing that a GUI should absolutely avoid is using batch files, that's gonna be trouble even on Win 10. For Unicode only VapourSynth will work, AviSynth don't support it.

https://de.wikipedia.org/wiki/Windows-1250

[RipFan]

Was wondering what the most efficient way to do batch encodes with MeGui?
Say I have Example S01 with 10 episodes in that folder and Example S02 with 10 episodes in the other folder.

If I get my settings/one click encoder script/settings how I want. If I add the first folder, it only adds the first episode to the queue. While it's encoding if I add the 2nd folder it adds S02E01 next in the queue. Then it just encodes all over the place.

Is there a way I can fix this, other then taking all the episodes out of the 2 folders and placing them in one. Is it possible, when I add a folder to the one click encoder, for the entire list of jobs to go ahead and come up in the queue list? So that, when I add another folder it just adds under there. Instead of just S01E01, it does S01E01(index,encode,mux) S01E02(index,encode,mux) etc etc?
https://i.imgur.com/RyQXnXJ.png

The above wouldn't be a big deal. However, if I was to go ahead and add S03 to the mix to get encoded. It would prioritize it after S02E02 and completely skip the rest of S02 until it was done with S03. If I'm doing something wrong, please help. :)


Also, why does every other time I start MeGui I keep swapping between versions of this update? Each time I try to encode with the newer versions I get an error somewhere in my batch.

https://i.imgur.com/CEgbjh2.png

In your first image, the job 2 (mkvmerge / muxing).
Is this something new in MeGUI?
I've been using MeGUI for 7 or 8 years now, and there was only 2 jobs for 2 pass encoding option.
Why this job 3? Is it to mux de first and the second pass?
Can someone help me with this question?
Thanks in advance.

Can anyone tell me if and how it is possible to extract opus audio with MeGUI?
It says unknown.
I installed the opus package but it still can't be checked in HD streams extractor.

(5) MP1, MP2, MP3 audio
(6) AAC audio
(7) MLP, TrueHD, TrueHD/AC3
(8) FLAC

Can you recommend a program to extract opus from mkv?

There are a bunch of mkvextract frontends you can find at videohelp.com. I'm using staxrip of course.

Did you try to enable the package in MeGUI?
Open MeGUI, select "Tools" and then "Update".
Scroll down untill you find "opus". Right click on "package disabled" and choose enable and then update it.
Try it. If something goes wrong, do the opposite and disable it again.
This is just a guess.

Does anyone know where to set 1-Click to use FFms instead of L-Smash for default file indexer? Disabling L-Smash in update doesn't work as it enable itself back when 1-click running for whole folder.

If I'd like to manually update x265 exe, which one should I use from here: http://msystem.waw.pl/x265/ ?
Thanks in advance

[LigH]

You should not, a new version may alter some command line parameters or preset balances, so MeGUI may not support a new version optimally.

Hey there friends , been a while since i was here .
Just recently i decided to become part of a group who rented a remote desktop to encode and do some video editing stuff and all.
i know just a tiny bit regarding megui and I use that to re encode videos to save space and make them play directly on my TV.

My issue is whenever someone else is using a high percentage of CPU lets say may be above 80 or 90% , the encoding speed of megui x264 goes down like anything .
When usually first pass runs at around 60 to 120fps it goes down to 3 or 4fps
and same is the case with second pass too. ( i use 2 pass encoding )
the cpu usage in first pass is around 8% at my end , whereas the other user is consuming more than 90% of it.

I have tried adding --threads manually as well into the x264 command line but still no use.
CPU is pretty good Intel Xeon E 2650 with 64gigs of ram
Ram is always available , more than 50% is always free.

I don't use any sort of filtration in avisynth script
here is an example

LoadPlugin("F:\TEST\megui\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("F:\files\mammoth.mkv")
#deinterlace
#crop
#resize
#denoise

here is x264 command line
--preset slower --pass 2 --bitrate 1500 --stats ".stats" --ref 5 --qpmin 10 --qpmax 51 --merange 24 --threads 96

just yesterday added the threads manually to see what it can do., it made encoding faster when i was the only one consuming resources otherwise the threads count is always at default as set by the preset.

all i wish to know is how can i set megui to use enough cpu power or whatever it is so that i get a decent fps
Thanks

ThanksWhen someone transcodes the processor is doing the same thing for them in real time as megui does for you slowly for more quality.

There is no magic fix. If plex calls for the CPU power it's going to get it ad megui is lower priority.

If plex didnt get it their steam would buffer or hang.

If you want it to go faster you need to look into high core count thread rippers.

What is best practice to understand transparency.

Transparency is a subjective goal.

My goal is a compromise between quality and size and try to obtain, more or less with a crf 18:

I_QP: 16
P_QP: 18
B_QP: 20

I know it is not absolutly transparent but is enough for me.
I think than crf less than 16 is to waste bitrate but each user must select their goal.

How to read from this.

[sneaker_ger]

It means x264 used 1039 I frames, 28114 P frames and 107619 B frames.
https://en.wikipedia.org/wiki/Video_compression_picture_types

The average quantizer for I frames was 14.13, for P frames 15.54 and for B frames 17.64.
https://en.wikipedia.org/wiki/Quantization_(image_processing)

The average sizes were 133071 Bytes for I frames, 57455 Bytes for P frames and 31151 Bytes for B frames.


So these values are only interesting for computer scientists and not so much for end users.

[Merlincool]

So these values are only interesting for computer scientists and not so much for end users.

I thought this has some technical details. Sone were I read if ipratio and pbratio is equal that means it's good encode? Or is it something else?

No, the intention of I/P and P/B ratios is: You can configure the encoder in a way that it uses finer quantization for frames which are used a lot as a reference (the quality of many other frames depends on its precision – thus, mainly I frames) and coarser quantization for frames which only depend on other frames but are not referenced by others (their lack of precision is not inherited and not visible for a long time – thus, mainly B frames). Many people already spent a lot of time in testing which ratios produce a good compromise between efficient encoding and good quality retention. I/P and P/B quantizer ratios don't have to be equal, they may be both small (only little more than 1.0) or both larger or selected independently ... the encoder has its defaults, which may depend on selected presets and tunings, and you can still override them manually. But both are settings to prepare the encoder, not results telling much about the quality of the encoded video.
