MeGUI: General Questions and Troubleshooting Thread

[jlw_4049]

Hello, I used to encode videos to x264 with One Click Encoder, Constant Quality, in x264 config page, of around 22.0, and this 30 minute tv recording used to come out to around 900+ kbps and 200-250 MB. I encode the same exact show and now the end result is 600 kbps video and 70-80 MB and the video looks super bad.



Was there a recent change to the profiles or something? I ask because I recently upgraded MeGUI from 2828 to 2913. First time I upgraded it in like 2+ years I think. I am wondering if this related.Probably the x264 version change

Was there a recent change to the profiles or something? I ask because I recently upgraded MeGUI from 2828 to 2913. First time I upgraded it in like 2+ years I think. I am wondering if this related.

Last year someone at VideoHelp upgraded to 2913 and complained about inconsistent file sizes when encoding the same video more than once.
https://forum.videohelp.com/threads/399221-MeGUI-x264-Avisynth-encodings-keep-coming-out-at-different-filesizes

Maybe the bundled x264 is broken, or whatever MeGUI uses to pipe the script output to the encoder these days (ffmpeg?).
I'm still on XP and for 32 bit windows there's no middle man. The script output is piped directly to the encoder. I'm using MeGUI 2913 though, and the file sizes are fine (although I think I rolled x264 back to the previous version as the bundled one no longer runs on XP).

I'd suggest rolling x264 back to the previous version and if that doesn't fix it, try rolling back ffmpeg or whatever MeGUI uses these days, assuming you're running a 64 bit version of Windows. 32 bit MeGUI encodes with 64 bit x264 on 64 bit Windows, and I think it uses ffmpeg to pipe the video to the encoder. I've no idea if the same applies to the 64 bit version of MeGUI.

Hi,

1) I want to re-encode a lot of video files (FROM mpeg2-mkv TO avc-mkv). The only requirement is: output bitrate should be half of original (i.e. twice smaller).
All original files has different bitrate, so output bitrate should be calculated somehow. But how?

2) How to preserve tags (Movie name, Released date, Comment, DIRECTOR, Url, WRITTEN_BY) from original mkv-files? New encoded files doesn't contain these tags.

Thank you in advance!

[StainlessS]

Go,
This don't comply with your requirements, but as no-one else replied I thought might be something to play with.
Maybe you can make some use of it.

Go.Bat [see REM's ie REMarks]

REM We DO NOT LIKE SPACES IN FILE NAMES (REM == REMark ie comment)
REM We DO NOT LIKE ACCENTS IN FILE NAMES.

setlocal

REM Where to Find ffmpeg
set FFMPEG="C:\BIN\ffmpeg.exe"

REM Where to get INPUT files, No terminating Backslash, "." = current directory (ie same as dir .bat file)
set INDIR="."


REM Where to place OUTPUT files, No terminating Backslash. "." would be same as .bat file, ".\OUTPUT" = OUTPUT folder in same directory as bat file.
set OUTDIR=".\OUTPUT"


REM OUTPUT:- Video: codec=x264, Preset=Slow, CRF=23, Audio: aac 96Kb/s, Output in mkv container

Pause


Try changing SET CRF=23 line, lower for higher quality and bitrate.

Update the update.xml file in update_cache subfolder as
<ffms type="file" requiredbuild="2624" build="64">
<filepath date="2021-01-17" version="20201123">ffms2-20201123-64.7z</filepath>

Thanks for that. :)

I keep getting a Process exits with error: 0xC0000005 STATUS_ACCESS_VIOLATION(-1073741819) message around two hours through rendering. This started happening after I installed FFmpeg into my C-drive in order to properly encode using VapourSynth, but I have its package disabled on MeGUI. In addition, this error only occurs with these two files I'm attempting to render (it successfully renders DVD files and smaller BD files), but I've succeeded in being able to render them previously, but in that case, I was rendering them into 10bit and here I'm rendering them into 8bit. I'm unsure if this is an issue where MeGUI will simply fail rendering if left running too long or what.

Maybe memory access violation, I would take a look in Windows Event Viewer, maybe it has a log telling in which module it happened. It can be an avs or filter or hardware or source file issue.

[AOmundson]

Event Viewer didn't record anything, but it was able to finish rendering when I had deinterlacing turned off. This is fine except the whole reason I'm using the current script is that I'm trying to deinterlace the footage.

Should I just run it through the new script then re-render it through the deinterlacing script?

[LeXXuz]

Just a wild guess, but some filters still don't like resolutions not divisible by 16 or at least by 8.

Try to crop(240,6,-240,-2) from your 1080p source and see if that may help.

Hi,
My source audio is AAC 128kbps VBR and I'd like to slow it down from 25 to 24 in MeGUI, but I want to preserve the original bitrate with VBR and MeGUI only offers "quality" adjuster for VBR. Is there no way to set the target bitrate?

I could just set it to 128 CBR, but I don't know if it's appropriate to re-encode VBR to CBR (not sure if there are drawbacks).

https://i.imgur.com/3fL1E0u.jpgEncoding anything from 128k to anything else will have major draw backs. Slowing the audio down or speeding it up is impossible without re encoding.

Yes, I'm aware that 128 is low quality to begin with, but let's say then that I have 384kbps audio instead. My question is can I set the target bitrate in MeGUI for VBR? If not, which other program can I use?

And my secondary question was, when converting from VBR, is it always best to convert to VBR, as opposed to CBR?

I'm doing these conversions because I care more about preserving the cinematic FPS (24) than dealing with a small loss in audio quality, which most people couldn't even hear.

The way recommended to encode aac at a fixed average bitrate is use the Constrained mode (CVBR) of qaac.

You need install the package in MeGUI, and Options -> External Programs -> Enable QAAC

Thank you for the recommendation. Are you sure I don't also need another program like iTunes? I installed the QAAC package and enabled QAAC, but it didn't appear the next time I opened MeGUI.

[tebasuna51]

... Are you sure I don't also need another program like iTunes?...

This is my MeGui64 qaac folder:

Directorio de C:\Portable\MeGUI64\tools\qaac

You can install the full iTunes or follow the 2º option in install.txt to obtain the portable folder QTfiles64 needed.

I recommend use this old version (https://forum.doom9.org/showthread.php?p=1924798#post1924798):
iTunes 12.9.3 (64-bit) (https://www.filehorse.com/download-itunes-64/43993/)

Thanks again, I managed to get it installed. However, I'm finding that the CVBR option does not produce a file with the targeted bitrate. When setting 128kbps as the target, the output is 104kbps. To get 128kbps, I have to set the target to 160kbps. Is this normal?

[tebasuna51]

Is this normal?

No, maybe is a very compressible audio (without high frequencies) and use less bitrate than preview.

Hello all,

Sorry in advance if this was answered already.

I've started dabbling with some 4K HDR10 movies and found MeGUI doesn't seem to be handling them properly. The color output looked dull and washed out.

Did some quick research and found some info that makes it seem as though the source isn't be treated as a full 10-bit source.

Is MeGUI even capable of handling these movies? I'm trying out another encoder, Fastflix, that seems to have been written primarily to deal with this issue.

When using the adaptive muxer you are able to set a name for the video stream, but when the adaptive muxer is brought up using the autoencode function the video portion is grayed out. Is there an option that allows me to add a name to the video stream using the adaptive muxer via autoencode?

[TsUNaMy WaVe]

I have a problem with the chapters part of the MP4 muxer that I never had before.
I used to add the chapters files before auto-encoding my video. It all worked well. My chapters are in UTF-8 because they use Hebrew letters.
Not too long ago I got a new PC. Unfortunately when I use the same method as before, the Hebrew letters get messed up and become jibberish. When I mux in an external program (like MKVToolNix GUI), I have to specify UTF-8 for the chapters to show properly.
Is there any way to force the muxer in Megui to encode the letters in utf-8? I prefer to do everything in one program as before, and not have this extra step.

Hello.
I'm having an issue when using the HD Stream Extractor in MeGUI when it comes to audio files of 24 bit.

It adds distortion to the audio regardless which format I use with the exception flac (thankfully) from wav, wavs, W64, RF64 all no good. This isn't the only program either as Audio Cutter also gives the same result.

As I have multiple episodes bunched together into one m2ts file making a back up copy annoying.

Is there a work around to this? :eek:

[tebasuna51]

... audio files of 24 bit.

It adds distortion to the audio regardless which format I use...

Please put the log file.

The MeGUI HD Stream Extractor tool is a GUI for the eac3to.exe program, and AFAIK eac3to don't have problems extracting and recoding audio files of 24 bits.

Maybe if we know the sources and the output format desired (the log file) we can help you.

Does it matter which MeGUI version its using? I'm still using version 2525 simply because it's the very last version that supports .h264 files to encode. I've tried on MeGUI 64 bit version 2896 with eacto ver 3.34 which only allows W64 nothing else and still adds distortion to the audio.

I'm not sure if it's needed but I also updated RawSource (http://avisynth.nl/index.php/RawSource26) version v0.0.1 but no improvement. :thanks:

Oh, DTS audio I know has no issues with 24 bit either. Same with TrueHD audio. It's just with PCM / WAV there's an issue. The issue persists in non-MeGUI programs such as Audacity when encoding into .wav higher than 16 bit.

Maybe MeGUI just can't do 24 bit for some reason even tho https://en.wikibooks.org/wiki/Eac3to/How_to_Use#Command_Line_Syntax says it can do it.

[tebasuna51]

The MeGUI log file (like the attached) supply more info (program versions, mediainfo of source, etc.) than the eac3to log.

Nope, the eac3to version is the same.

The last MeGUI version is 2924, and all versions admit all outputs (see Settings in HD Stream Extractor window)
"supports .h264 files to encode"?

I can't reproduce the problem (see log), the output file is bit-identical to the source. No problem with 16 or 24 bits PCM tracks.

I'm not sure if it's needed but I also updated RawSource version v0.0.1 but no improvement.
This is a plugin for raw video not needed here.

The issue persists in non-MeGUI programs such as Audacity when encoding into .wav higher than 16 bit.
Then you have a problem with the source or your player.
If you can upload a sample of your source we can test it.
I think than MeGUI, eac3to and Audacity works fine.

[dREV]

The MeGUI log file (like the attached) supply more info (program versions, mediainfo of source, etc.) than the eac3to log.

Oh, right forgot MeGUI also has a log file.

Preliminary log file only. During closing of MeGUI the well formed log file will be written.

I like to establish where it states "There are 15 packages which can be updated" all of it has been updated long ago and everything I can possibly update that still enables MeGUI to run without problems as I attempted to update the MediaInfo but would not run after certain versions.

Also where it says "Haali Matroska Splitter is not installed" is so too installed it doesn't know where it is but it's installed via k-lite codec pack (https://codecguide.com/) and I think "Haali DSS2 is not installed" requires Haali splitter? Not sure.

The last MeGUI version is 2924, and all versions admit all outputs (see Settings in HD Stream Extractor window)
"supports .h264 files to encode"?

I know but can it encode using it? Was my issue. Is version 2924 an unreleased build? I only am seeing version 2913.

I can't reproduce the problem (see log), the output file is bit-identical to the source. No problem with 16 or 24 bits PCM tracks.

My motherboard is a MSI B350M Gaming Pro on Graphic AMD Software ver 20.11.1 with Realtek High Definition Audio Driver ver 6.0.8703.1. Under the settings I have it set to 24 bit, 96000 Hz (Studio Quality).

Then you have a problem with the source or your player.
If you can upload a sample of your source we can test it.
I think than MeGUI, eac3to and Audacity works fine.

When using foobar2000 it plays audio music files in 24 bit 48 kHz and 96.0 kHz just fine. I've been using MKVmerge to extract the 24 bit audio with no distortion. I also use MPC-HC video player (included with k-lite codec pack) to test audio quality, so I can decode just fine just not encode above 24 bit without issue.

Is there some .wav output option that I'm not aware of that I can change to "Auto" when it comes to bit depth like it has on the foobar program? Which of course the .wav gives distortion on it too when going to 24 bit.

I don't think its necessary to provide a sample but if you really want how exactly do I do that? I seem to have forgotten how to do a short clip using MeGUI from a lossless source. :scared:

Megui -> Options -> Extended -> Auto Update -> Use development update server -> Save

Of course is recommended update all soft, but your issue is not a problem of versions or soft needed. Your issue only is with eac3to and it is tested to work without problems converting PCM 24 bits, from m2ts, to WAV 24 bits files.

eac3to don't need encode, only need swapp Big Endian bytes from PCM in m2ts to Little Endian bytes in WAV files, and reorder the LFE channel.

I've been using MKVmerge to extract the 24 bit audio with no distortion.
MKVmerge can't extract wav files from a m2ts. You need convert to mkv and use MKVExtract.
If you do so with the track 3 of the 00002.m2ts the output wav play without distortion?

I don't think its necessary to provide a sample but if you really want how exactly do I do that?

To cut a sample of your m2ts you can use tsMuxerGUI (https://github.com/justdan96/tsMuxer/releases/download/nightly-2021-04-30-02-13-20/w64.zip) (tab Split & Cut)

I'll check it out later as I remember a version where no matter what I did the update would not stop and kept annoying me. Which I prefer to keep it off.

Is there a way to change how MeGUI uses eacto? Or maybe change it from within eacto so MeGUI can use it as per my instruction? Like it does with the audio portion in MeGUI, FLAC, AC3, AAC, Vorbis but it doesn't have .wav for some reason.

As you mention I notice I use a program called Spek and I see that when I drag/drop the m2ts file into it it says:
PCM signed 16|20|24-bit big-endian for Blu-ray media, 2304 kbps, 480000 hZ, 2 channels

However with the extracted .wav it says:
PCM signed 24-bit-little-endian 2304 kbps, 48000 Hz, 2 channels.
How did you switch it?

MKVmerge can't extract wav files from a m2ts. You need convert to mkv and use MKVExtract.
If you do so with the track 3 of the 00002.m2ts the output wav play without distortion?

Right, no distortion when I use MKVmerge it'll change the extension to .mks which has been fine to get around my issue. But when there's multi-episodes in 1 m2ts file I am in need of MeGUI's Audio Cutter program.

Otherwise I have resorted to attempting to cut them in MKVmerge using its split mode but it requires more time and effort for me as one mode may not work but another mode may. It's faster with AVS Cutter > Audio Cutter but as mention Audio Cutter seems to encode it into .wav which adds distortion if it's above 24 bit.

To cut a sample of your m2ts you can use tsMuxerGUI (https://github.com/justdan96/tsMuxer/releases/download/nightly-2021-04-30-02-13-20/w64.zip) (tab Split & Cut)

Thanks so much for the cool program! I'm gonna keep it too. Will be a big help on those annoying multi-episodes I hope.
Here are the files (https://mega.nz/folder/AcdSDBBD) and the key: D-Z-NzO0mDDsSbAyW0ulCA In addition I've included the result of this split .wav file extract using eacto in MeGUI so you can hear it for yourself. My MeGUI ver 2525 is also included, so you can see exactly how it is at my end but only has the eacto in the tools folder.

[tebasuna51]

Is there a way to change how MeGUI uses eacto?
There are some GUI's for eac3to, the included in MeGUI is the HdBrStreamExtractor but you can use other eac3to GUI.
I make one UsEac3to (https://forum.doom9.org/showthread.php?t=145574) but it is not the problem.

Or maybe change it from within eacto so MeGUI can use it as per my instruction? Like it does with the audio portion in MeGUI, FLAC, AC3, AAC, Vorbis but it doesn't have .wav for some reason.
In the MeGUI Audio encoder section you can use a AviSynth decoder plugin
like LWlibavAudioSource (and others) to open your m2ts, but you are right
does not offer WAV output. If you want that you can use BeHappy than only can manage audio with AviSynth but with many more options.

PCM signed 16|20|24-bit big-endian for Blu-ray media, 2304 kbps, 480000 hZ, 2 channels

However with the extracted .wav it says:
PCM signed 24-bit-little-endian 2304 kbps, 48000 Hz, 2 channels.
How did you switch it?

Exact, the audio samples are the same but the bytes are ordered like big-endian in a m2ts (and the LFE channel is the last) but in a WAV file the bytes must be ordered little-endian (https://en.wikipedia.org/wiki/Endianness) and the channel order must be: FL,FR,FC,LFE,SL,SR (without differences in stereo)

The players know how must manage that audio data without problem.

Right, no distortion when I use MKVmerge it'll change the extension to .mks which has been fine to get around my issue.
If you load a m2ts in MkvToolNix and output only the audio make a .mka file. If I do that the .mka play fine but exactly like the .wav extracted by eac3to.

But when there's multi-episodes in 1 m2ts file I am in need of MeGUI's Audio Cutter program.

For me the MeGUI's Audio Cutter work fine with the wav extracted but there are other methods like MkvToolNix or tsMuxeR to split the audio.

Here are the files... In addition I've included the result of this split .wav file extract using eacto in MeGUI so you can hear it for yourself.

Sorry but your wav file play fine here, and is bit-identical to the obtained with my software.

All sound fine, your m2ts, your wav and the .mka or wav extracted be me, seems is a problem in your players with wav 24 bits.
Tested here with foobar2000, GoldWave, Audacity, VLC, MPC-HC and all sound fine.

I used that program when I could not figure out how to extract eac3 audio in MeGUI. But it took me some time to kinda understand how to at least re-encode the audio. I haven't spent more time on figuring out the rest of it.

like LWlibavAudioSource (and others) to open your m2ts, but you are right

Thanks for introducing me to that program. I'm pleased to have such a program now but I wish it had a specific frame cutter with maybe a video frame to easily capture the frame, so I can completely replace both AVS Cutter and Audio Cutter. :(

Tested here with foobar2000, GoldWave, Audacity, VLC, MPC-HC and all sound fine.

Going by your words that you had no issue with the files and even the .wav file I extracted myself I had to do some investigating and came to the conclusion that you are correct and it is the programs I been using. Strictly the program MPC-HC and Potplayer video players.

Following what you've said that the video player knows what to do with the data and everything else you've said got me thinking what if I put a video with that distorted audio therefore "switching" from big-endian to little-endian which then turns out no distortion! :eek:

So when I use MPC-HC strictly to listen to the audio for any distortion I hear the distortion when its in PCM (.wav) but not when I tell HD Streams Extractor to encode it into FLAC or any other audio > play it in MPC-HC there's nothing. :confused:

Then I tried to place the distorted .wav file into my foobar2000, increased my volume to max to see if I can hear it and nope, I heard no distortion! Since its specifically for audio files which I shouldn't be surprised but I was. :)

Then I investigated MPC-HC just raw and... no distortion! :rolleyes:

So now its one of the filters I'm using together with MPC-HC and turns out it was FFDShow Raw Video Source that's been causing the problem. Not sure why when it's for video. This filter I used sometime back because I could not watch DVD for some reason, so I included it specifically to watch my DVD. I also use FFDShow Audio Processor to enhance the audio even more together with all of the LAV filters but that didn't cause any issues just the video filter. :angry:

So reinstalling k-lite codec pack without that filter but leaving in FFDShow Audio Processor leads up to hearing no more distortion in both video players! :cool:

So I like to deeply apologize for wasting your time and humbly thank you for it as well to get me to finally understand why its been distorting all this time. I was so use to doing it this way for years never thinking otherwise as I did try many times to understand why but not figuring out that it was the filter in my video player. I didn't even think about listening to it in foobar2000 which again why I was surprised. :stupid:

:thanks:

Sorry for wasting your time with me honestly.

I heard some really good things about this program but I had never used it. Can anyone tell me some good things that you can do with MeGUI? I am looking for something to make my experience easier.

[Atak_Snajpera]

Define "good things". Do you mean "world peace" or something else ...

I was looking for features that will allow me to create scripts or upscale multiple videos.

Surely you've heard of RipBot264, if you know what you're doing, it should "fill the bill", and with the DE feature, it'll get it done quickly, as well :)

Hey guys, when I used to encode blurays way back in the day I mainly used Handbrake and Megui. Is Megui still the best encoding program for blu-ray encodes, which maintains as much quality as possible? I have read that Handbrake is not truly a 10 bit pipeline and it really seems like x265 10 bit encodes will be the best quality for my backups. Is Megui true 10-bit ? Also, from what I have read, Handbrake can use up to 16 cores (I'm not sure if this counts threads as well), can Megui do the same? I'm in the market for a new CPU so that will definitely sway my decision. Thanks so much guys! Your help means a lot to me!

[tebasuna51]

Forum Rule 12) ... 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!

MeGUI can use AviSynth with many free decoders and filters and the free encoders x264/x265, you can select the desired quality.
But, of course, there are other choices.

Is Megui true 10-bit ?
Of course (like x264/x265 are).

All encoders can use all cores you have.

Thank you, I apologize for asking what's best. I realize this is going to differ from person to person. I may think something looks great, but someone else may think it is lacking detail that the orginal source had. I appreciate you taking the time to respond. I really wish there was a more up to date tutorial on Megui and all of the advanced settings though. I read a guide on here but it was very outdated.

To be honest I neither have the time nor the ambition to familiarize myself with a completely new encoding GUI.
