MeGUI: General Questions and Troubleshooting Thread

[wakebrder]

Is only a container (mkv -> m2ts) issue. The video or audio tracks are the same.

For instance:
a.mkv 4613434731 bytes

converted with TsMuxer:
a.m2ts 4888528896 bytes

Ok, so is this a constant variable? Your calculations put the BD filesize at approx +275 MB.

On my current projects, I have tried reducing my target filesize in MeGUI by approximately 300 MB. Hopefully that will be enough cushion for the MKV>>Bluray conversion. Have not tested yet due to the holiday weekend.

Maybe the author(s) of MeGUI could provide an BD structure output in future releases to avoid this situation. (Excellent program by the way)

Thanks for the replies!!

[Sharktooth]

we have m2ts support on the to-do list.

[Rodger]

Just one short note.

Why are you using the mkv container?

I always encode to RAW!
There is no container needed for the video.
Finally I mux via tsMuxer.

[Sharktooth]

we have some containers as output depending on the encoder used: AVI, MKV, MP4 and finally RAW stream (not a container and only for x264 and xvid).

Ripbot will give you correct filesize.

Anyone have MeGUI crash an cause the system to reboot on them?

Was doing a 720p encode with high priority, MeGUI was using 1.3GB or memory (okay since I have 4GB) and quad core cpu was running about 90%-95% (all cores).
I've done it before on short videos no problem, but this was a longer video. The encoding process was about 80% done when system rebooted.

[LigH]

I find it quite annoying that the preset importer windows stay behind the general updater window, possibly due to some stupid Windows XP behaviour opening new windows of the same application in the background... you wait for the update to advance, nothing happens, you close the updater window, and MeGUI crashes - and then you realise that the updater window waited for the preset importer which got opened behind the updater window.

Could you please try to force the preset importer windows to the foreground? I hope one or two "move to front" window messages will be enough...
__

P.S.: Or I usually thought that a "modal" dialog should always appear on top of its parent window. So calling the importer in a modal way may be a solution?

i think you have a hardware problem (probably overheating or something else...) a software like megui cant make the computer reboot (expecially a hard reboot) unless some hardware is not working properly or there is a major bug in the OS.

Yeah, guess it could be because of heat. But the system has six 120mm fans (two of those on Thermalright Ultra-120 Extreme CPU cooler) and one 200mm fan all set to max speed.
Idle the CPU runs at 26c, so I don't see how it could go up so much as to cause a reboot under load.
Guess I'll stick to normal priority for now.

[Sharktooth]

then check your ram with memtest86. also check your harddrive surface for defective sectors.
it may also be related to the avisynth filters you used (did you use fft3dgpu or some other gpu plugins? they may cause that problems since video card drivers may make your PC reboot since they interact with the kernel ... at least on XP and previous M$ OSes... also if you used those plugins, check the GPU temp under load...)

I hope most of those are exhaust fans otherwise your case is gonna be like an oven :p

If it was a hard reboot then it's most likely a RAM issue; bump the voltage up a notch if you dare :p

@Sharktooth
Hard to run a harddrive surface scan when it's in a 1.7TB Raid0 setup.
However, I did run a surface scan on each drive using the manufacture's (WD) program when I first picked up the drives.
All three disks came out with zero errors.

As for the memory, have it set to the default manufacture settings. But will try the memory test program.

You should disable automatic restart in your advanced system settings to get the bluescreen message. Or you could check your systems log. The message would help narrowing the source of your problem.

[Sharktooth]

if you cant find it, the event viewer is in the administrative tools.

If I ever want to recreate the error, I'll disable that and see if it comes up again. However, I'll see if I can find the system log from earlier today for the crash (after the memory test).

Memory test is running now. Didn't think it would be a near all night thing though. 25% done after 18minutes.

On a side note, I just finished encoding a good twenty videos and was getting ready to encode their audio and mux. However, the MeGUI - Nero AAC increase volume automatically setting is giving me an issue.

With it disabled, the audio has a good levels on my main system. But with my laptop, the volume is extremely low (even when set to max speaker volume). If I enable increase volume, it plays back much louder on the laptop, but I don't like how it sounds on my main system (sounds peaked out).
(both systems are using the same software decoders)

Since I'm encoding for internet distribution I'm kind of confused as if I should enable or disable. :confused:

[Sharktooth]

did you try ffdshow's volume option on your lappy? you can set it up to your preference.
however, if you keep the option disabled, the audio will be encoded as is and in the case of a 5.1->2.0 conversion the volume will be lower since no DRC will be applied...
with the option enabled, the volume should be "normalized" and should never clip... if it does then look in your souncard software setup and disable any volume gain option.

I can't do much since all my work is on the main system. But after memory test is done, I'll try the ffdshow volume option and see what it does with the laptop.

The reason I kind if don't want to enable increase volume is because when I check the wav forms in adobe audtion, the audio has no clipping/peaking and overall good range as is. So would rather leave it at the original levels. But if it plays back too low for some, it creates problems (like what I found on my laptop)

When enabled, doesn't it preform gain up until just before the point of clipping? I'm encoding both Stereo and 5.1 AAC, but the profile in both cases is set to keep original channels.

[Sharktooth]

just analyze 2 encoded files (one with increase volume option enabled and the other with the option disabled) with audacity or any other audio tool that will show the waveform to see if there is clipping.
however, i dont exactly know how the volume gets increased since it's being made by an external tool.

Don't think that would work since Audition/Audacity won't allow import of AAC files.

Anyway, memory test just finished and passed with no errors.
The event viewer doesn't seem to list an errors in the application tab for when the crash happened. All I see is an error for mkvmerge.exe, but think was from when the program just locked up during a mux. The hard reboot was during an encode.

[Avenger007]

Run Prime95 overnight. If no errors then the crash was probably just a fluke. If it happens again try bumping up some voltages for stability :p
I doubt it's a software issue you're having but if Prime95 doesn't report errors then it's worth looking into.

[gav1577]

I was having crashes like you a few weeks ago it was due to overclocking my cpu and not giving the cpu enough voltage if u have overclocked like the guys said prime 95 8 hrs minimum large FFTs check ur load temps are within safe guidelines with core temp
if it passes ok run after that run prime this time blend test for the ram if it passes that ur system should be stable if it does not then you can try increasing your vcore increment by increment you could also try
increasing your nothbridge voltage slightly too. But try vcore first
dont forget what sharktooth said about surface test too i know u have a alot of hdd space but do it while you sleep its worth it. ive lost count of times peoples pc's have been crashing due to disc errors BTW if using windows make sure you check scan for attempt recover bad sectors when using check disc :)

[Sharktooth]

Don't think that would work since Audition/Audacity won't allow import of AAC files.
use neroaacdec to decode to wav file...

[XhmikosR]

Hello, guys and thank you for keeping updating MeGUI. I encounter a problem with MeGUI and Vista 32bit (I don't have anymore XP, but IIRC this problem wasn't present in XP).
I think that someone else has already mentioned it some pages before in this topic, but I'm not sure.
Let's say I load an avs script and enqueue the job. When I try to load another avs script then MeGUI locks completely and I have to kill the process via task manager.
If I just load one avs script, close MeGUI and then add another avs script, no problem there.
The scripts I try to load to MeGUI, of course, play just fine with MPC so it's not something Avisynth related (I use 2.57 tsp's MT version).
If you need any other information, I'm happy to help solving this thing.:)

MeGUI Version: 0.3.0.2004
OS: Microsoft® Windows Vista™ Business SP1 (6.0.65536.6001)
Framework used: 2.0 SP1 (2.0.50727.1434)

[Sharktooth]

try with the non MT version of avisynth.

[XhmikosR]

Ok, I narrowed down the problem to Avisynth MT 2.5.7. If I use the original Avisynth 2.5.7 or the latest 2.5.8 RC4 I can load any avs and enqueue it without MeGUI locking up.
So, isn't anything you can do to fix it, please? If you can't, it's not that big deal, I appreciate all of your work.:)

[Sharktooth]

well, avisynth MT is quite unstable... so, no, i cant fix it in megui. it's an avisynth MT issue.

[AKarpo]

My MeGUI prompted me to update to the latest version (which I did) however now when I use the D2V creator, I don't see any audio tracks to select and my .ac3 stream is absent upon completion.

Before with my over-the-air HD recordings, I never had this problem. In fact just before this I encoded the same file I'm now attempting to encode at a different resolution, and it worked fine pre-update.

Is there a new procedure?

[Sharktooth]

uhm... that could be an issue with the new code. workaround: use dgdecode to manually demux the audio.
please make a bugreport in the megui project bugtracker on sourceforge (doesnt need registration) posting all the details.

thanks, will do.

[Frank_UK]

I have exactly the same problem.
Using an mpeg2 file as input, D2V creator does not demux the audio.

[Kurtnoise]

not really a bug...just a feature missing. ;) That should be fine in the next build.

[Sharktooth]

the next build is already up ;)

[rack04]

Is there a reason why the Select Audio Tracks is grayed out in the D2V Project Creator?

[Kurtnoise]

audio tracks selection works only with vob/ifo files for the moment...

Alright that makes sense. I was working with ts and tp files.

Crash when using QTInput with ProRes Codec.

I am testing Apples newly released ProRes Decoder for Windows and am having MeGUI crash when I enqueue the encode.

The script opens and encodes fine with VirtualDub, it also opens with the MeGUI preview tool. I have tried MeGUI versions 0.2.6.x, 0.3.0.2002 and 0.3.0.2006. I was using AVISynth 2.57MT but replaced the dll with standard 2.57.
I also removed all Autoloading Plugins and AVSi files except for the QTInput dll.

Here is my AVS:


QTInput("S:\XS2l1p1\Test_ProRes.mov", audio = false, mode = 2, color = 2)
ConvertToYV12()



I also tried mode = 0 with the same result.

And the log from MeGUI:

I'm sure you all can't wait to get this fixed since everyone here is doing lots of HD captures with thier MacPros and thier favorite HDCAM-SR masters...:devil:

Thanks.

[Sharktooth]

that's an avisynth crash... megui crashes coz avisynth crashed...

[SynchronousArts]

That's what I first thought, but I could not recreate that error from other apps that read AVS as input. I don't know enough about the software APIs to understand this. I also thought the problem could be caused by the QTInput dll not knowing about the ProRes Codec.

Thanks.

-SA

[Sharktooth]

this could be quite difficult to debug, however, megui states it cant read the avs so it's definatly an avisynth crash. it could be due qtinput or some other factors.
can you post a small clip that triggers the crash?

[SynchronousArts]

I put up a small 3 Sec. on mediafire:

[Sharktooth]

works here: http://www.webalice.it/f.corriga/temp/Test-ProRes2.mp4
my avs: QTInput("Test-ProRes2.mov")
ConvertToYV12()
try removing any parameters (except the input file) from qtinput()
if you're using ffdshow, try updating it. also what version of qtsource are you using?

[Octo-puss]

I couldn't find any wishlist so I will ask here - is it possible to make it so that in x264 options dialogue you can press enter without having to click ok? It's very minor thing but somewhat handy especially when typing in some custom parameters. Maybe it applies to other windows?

[Sharktooth]

there is a feature request tracker on megui project page on sourceforge.
please add there your request

So this must be related to my environment etc. I tried 2 versions of the QTSource Plugin, QTSource_0_0_5a and QTSource_test_h264, they both do the same thing. Removing all parameters does not make any difference.

I'll check at Microsoft to see if there are newer .Net Runtimes.

Thanks

[poisondeathray]

@SynchronousArts - are you able to play the file back properly through MPC?

If not, reinstalling the ProRes codec

If yes, then it might be a problem with avisynth and/or plugins; I know you replaced the .dll, but you might have to do complete uninstall/reinstall

[SynchronousArts]

@SynchronousArts - are you able to play the file back properly through MPC?



Yes, the AVS plays in MPC and WMP10.

hi guys!

I'm using MeGUI 0.3.0.2008 with all updates. I'm capturing some movies from CineCinema channels on Hotbird with my SkyStar 2.8A and what I wanna do is to rip my captures to a reasonable size and quality file.

well, my preferred format is x264 (mkv), my input files are mpeg2 (recorded by ProgDVB) but i have not reached a final decision on which profile to use in order to have both quality and size, my maximum file size would be 700mb, which setting should I use to have the best quality in a MKV output file? which profile should I use? or what setting should be costumized to have the best quality in a maximum of 700mb file?

in addition, I'm using NERO AAC for encoding audio.

[saint-francis]

I'm trying to back up an animated TV series from DVD and about every third episode MeGUI's avisynth script creator can't detect the source type. It tells me some of them are progressive and that some are telecined and some it just gives up on. If I load one in AVSP with DGDecode_mpeg2source and skip through it frame by frame I notice no combing which leads me to believe that they are indeed progressive. I do notice many redundant frames; which I guess is typical of cartoons, I have little experience there. I would upload a sample but I don't know how to do this since each VOB is about 1 GB. If anyone has any ideas as to what the problem is or how I can cut a VOB to upload a sample please inform me.

P.S. The series is Avatar just in case anyone out there has already tried to work with it.

x264- DXVA SD-HQ which i would suggest and check it with bitrate calculator.

I think you have to get rid of Avisynt Script Creator with graph + manual avs method.

@Sharktooth, this file does not look right, it's all green but my source MOV was colorbars?

I've not had any progress with this, but I am able to workaround it by using the AVS Virtual Filesystem.
