MeGUI: General Questions and Troubleshooting Thread

[chipzoller]

Another Q that's unrelated...I want to use MeGUI as my complete "backup" software package and would like to start backing up some of my more-played DVDs. I do not have a hardware player that can play any MP4 content back, so I'm wondering if I should still encode XVid in MKV for future compatibility? I tried doing a test encode to Xvid with AAC audio wrapped in an MKV container (using mencoder for xvid) and the prog. crashes (or skips the encode steps, then exits) right when it gets to the encode steps. Since the app closes (and I don't see an option to disable this) I can't see the log and none is generated in the log folder.

So I guess this has 2 parts: Is MKV with Xvid a good bet for future device compatibility? & how can I stop megui from exiting on completion of queues/Xvid encode issue?

many thanks

[berrinam]

So I guess this has 2 parts: Is MKV with Xvid a good bet for future device compatibility?Probably not, because there is no commercial backing behind mkv.

how can I stop megui from exiting on completion of queues/Xvid encode issue?Sounds like a bug. Can you come up with a fool-proof way of reproducing it, or test it the way I described here (http://forum.doom9.org/showthread.php?p=810642#post810642)?

Thanks

[chipzoller]

I'm in the process of setting everything up to test this. It's important for me to note that meGUI didn't always behave this way. It only started in the last few encodes, and every subsequent encode has completed with the crash issue, even if the queue finished successfully.

When doing a MeGUI version upgrade, its ok to just unzip and overwrite the existing MeGUI installation right? Thanks

[berrinam]

Yep. It is.

[Bathrone]

Thanks, please allow me to show my appreciation for your work, Doom9s and the other people involved in this great app.

[berrinam]

Thanks, please allow me to show my appreciationNUP!!!! Why would I allow you to do that??? ;)

Thanks, anyway.

Hi, im using megui for the first time having used gknot and virtualdub to encode for a long time.

Im having a problem however, i have encoded my audio for this rip which went fine. But when i come to do the video, the two jobs i created (for first and second pass xvid) complete in under a second with no encoding taking place. Then jobs are then flagged as "done".

The avs its using to encode plays fine in MPC, so its not a bad avs file as far as i can see. Any idea what is causing it not to do any video encoding?

Logs bellow, thanks.

I had this problem when using mencoder for Xvid and found that everything was in place, but the build of mencoder I got either must have been wrong or gotten damaged somehow. I've had luck with the version of mencoder within the Mplayer package on the official site.

And I think Celtic_druid also has some builds of this?? In any case, the version at the mplayer site does work.

[PhAtfiSh]

thanks chipzoller, the version i used was linked in the sticky guide in this forum. Ill try another version.

edit: yep the build from the official site works.

[Dayvon]

Is there a way to have an AVI as the input in MeGUI?

Basically, I have a 2.5min uncompressed(RGB) 4.7GB video that I want to convert to -AVC in .mp4- or better yet -AVC in .mov- for net distribution. So I'm wondering since MeGUI MUST use AVISynth how do I get the script to work with MeGUI? I can't seem to find a way to get AVISynth to load the AVI.

Help?

[chipzoller]

Tools->Avisynth Script creator

[Dayvon]

Oh my word. Easiest. Fix. Ever.

I had tried that on previous versions and it didn't work. God bless you and curse my stupidity. Thx!!

[foxyshadis]

Opening the avi through megui (or dropping it in) will also bring up that screen nowadays. ;)

[thuongshoo]

HI ! MeGui has "Queu analyse pass" button. What is it used to ? I finished configure x264 config, and click that button, click "enqueu" button. Then, I choose queu tab, click start. I have no mp4 file. Why ? thank you ! :o

[berrinam]

Queue analysis pass queues an 'analysis' pass, which just plays through the video. This is useful for some avisynth scripts. If you don't know why, then it's not useful for you.

Why you don't get an mp4 file is a completely different issue. Check that you have created a video encoding job, and check that it has completed successfully (it should say 'done' if it has). Also check that you have MeGUI set up to point to x264.exe and mp4box.exe.

If you can't solve your problem after doing these, then try again, and if it still doesn't work, post your logfile from then.

[thuongshoo]

Thank berrinam! I have a mpeg file. Open it by Megui,.... choose tab filter, analyse. Megui suggest that I should deInterlace . Ok! I agree. ! My file is a music video. Singers sing 2 songs. At the first part of converted file, video and audio is sync absolutely. Oh! very surprising! When singers sing 2nd song, video and audio isn't sync. Why ?
I am said that MPEG video can be a hydrid video. So
analyse-step helps converting file with the best efficiency.
WMV is too. Megui a program base on AVIsynth. Why can't Megui open wmv files ? license ? I wite a avs file by myself and Megui still work :D I dont' know the way to analyse WMV files so I can't have a best file if I convert wmv files. Do you think that Megui will support wmv files ?
Thanks!

[berrinam]

What happens when you try to open a wmv file in MeGUI?
What is the script that you right yourself that works?

I suspect it may be that MeGUI is unable to detect the framerate of the wmv file. In that case, there is pretty much nothing you can do at the moment. I have a few planned extensions that might help later, but for now if you have a script that works and you want to analyse it, then do the following:
Write your script.
Use the program included in makeAVIs to create a fake avi file which wraps your script.
Open this avi file in MeGUI and analyse the video from there

[cjaar]

Want try megui for xvid encoding, but i coudnt find how do i encode xvid with CM, i see only h263/MPEG no custom matrix.
Is there a way to using CM in megui.

thx
cjaar

[berrinam]

Get 0.2.3.2135 or later.

Commit by berrinam:
- PAR is now in the video player, not the codec config (it's not a codec-specific thing, conceptually)
Neat, but the player shows up only if "Open Preview..." option is set. Is it possible to bring up the preview window without it or once it has been closed ?

[berrinam]

Hidden feature: Double-click on the input file textbox. That'll open the player.

[thuongshoo]

I open mpeg-2 file. DGIndex appear but it don't do anything. If I open mpeg-1 file, there is no problem. I try to run DGIndex at AVIsynth's plug-in directory, open mpeg-2 file, choose file/save. Oh! Job is finished within 30 seconds. Why ?

Thanks!

[Doom9]

@thuongshoo: please read this: http://forum.doom9.org/showthread.php?t=105160 and try again.

[ariga]

Hidden feature: Double-click on the input file textbox. That'll open the player.
Whoa ! Thanks. (And then ariga went clicking on every item in the GUI looking for hidden features :D )

[thuongshoo]

Doom9! you don't seem to know my problem.
Before, I load mpeg file into MEgui --> DGIndex will appear and work--> I have a .d2v file.
Now, ...., DGIndex doesn't do anything. I must choose file/open to load mpeg file into DGIndex and then I must choose file/save.

which dgindex version are you using?
Can you take the dgindex commandline ("C:\Program files\AviSynth 2.5\plugins\DGIndex.exe" -AIF=[E:\SES\[HD]Eugene-Cha Cha [MBC 2003.09.05].MPG] -OF=[E:\SES\[HD]Eugene-Cha Cha [MBC 2003.09.05]] -exit -OM=0)

start a command prompt, paste the line and run it and see what you get?

Also, could you try to rename the file so it has no brackets in it anymore? dgindex uses the [] brackets like the command prompt uses quotes for long pathnames/pathnames that contain spaces, and since your filename contains the same brackets, it may or may not confuse dgindex. It may still work from within dgindex because from the gui this never becomes an issue.

[wacco]

Help. Whenever I use Create new avisynth script, the video file (output) will appear while encoding at the right location, but when encoding is finished, it disappears!

[thuongshoo]

which dgindex version are you using?
1.4 beta 7 , newest
Can you take the dgindex commandline ("C:\Program files\AviSynth 2.5\plugins\DGIndex.exe" -AIF=[E:\SES\[HD]Eugene-Cha Cha [MBC 2003.09.05].MPG] -OF=[E:\SES\[HD]Eugene-Cha Cha [MBC 2003.09.05]] -exit -OM=0)
the phenomena is the same. DGIndex doesn't run.

[Doom9]

@wacco: you may know what you're refering to, but ask yourself if given the info you have given, would anybody who is not in front of your computer and watches what you're doing understand what you're trying to say? I know megui but I have no idea what you're talking about.

@thuongshoo: my last reply to you had another paragraph.. could you try what I wrote in that paragraph, too?

[Carpo]

i have 2 little questions - prob stupid but here goes anyway :)

i notice in 2148 that the mp4box.exe is 1.6mb - the one i have which allows me to add subs to a mkv is only 600K, can the one in megui support subs or should i use the ver of mp4box i have dated mp4box-20060505 ?

also seeing as support for neros new aac encoder is now in megui would it make any diff if used the sse2 exe instead of the one thats with megui (renaming it of course)

[berrinam]

I haven't been keeping track of which builds are the best to use. Consequently, since the files included in AutoUpdate were all chosen by me, they may or may not be the best choice, in which case someone should tell me so I can fix it. Anyway,
Yes, it is ok to use the sse2 version.
You can probably use whatever version of mp4box you want, as long as it is relatively recent. However, since MeGUI doesn't support vobsub subs in mp4box yet, it's rather pointless

[Carpo]

ok another stupid question on the way

i know to tick the source is anime for animation and such - but would it also apply to GCI - as in Final Fantasy Advant Children?

as i am planing to backup that next

[Latexxx]

I can't get Megui to start. Or actually it will start but it crashes when checking for updates. Replicated on two computers with Megui 2148.

Edit: I found 2149 and it seems to work.

This is not such a stupid question.

Let me outline what ticking 'Source is Anime' does:
It is only relevant for the deinterlacing stage
For framerate decimations (if there are any) it forces a different mode which is better for anime, in which there are many duplicate frames

So, if your source has lots of duplicate frames (like a duplicate every third frame, is what I mean), then, yes, tick it, but otherwise no.

[berrinam]

I can't get Megui to start. Or actually it will start but it crashes when checking for updates. Replicated on two computers with Megui 2148.I've updated many times from
2148 to 2149 without any problems. If this causes a problem again, can you report it on the bug report thread so we can try to track it down please?

[Carpo]

im more confused now than ever ;) how will i know if i have dupe frames will megui tell me ?

sorry for all the questions but i have only just started doing backups with megui so im still trying to find my feet as it were with all the options, but if i never ask i'll never get 100% out of it :)

[berrinam]

Well, generally you can tell whether you dupe frames from the kind of source:

Anime/cartoon sources tend to have lots of dupe frames, because it is too much work to do every frame by hand, so they tend to create it at 8fps or 12fps and double/triple frames to get it to 24fps. This is why with anime/cartoon sources, you can just assume that there are lots of duplicate frames.

With live motion sources (real life) you will tend not to get many duplicate frames, because it's real life, and nothing ever stays still. So you don't use this option for live motion.

For CGI sources...... well, I don't know, because I haven't looked at any, but I would expect that there is motion in every frame, because it is solely the computer's responsibility (not the GFX designer's) to insert smooth motion. But I'm not sure: what you can do to check is just to step frame-by-frame through the video in a few places throughout, and it will be pretty clear if the frames are duplicates, because they won't change much when you step to the next frame.

[markrb]

I don't know what of 2 things I did fixed my being able to autoupdate, but I will tell you both of them and maybe that can help solve the problem.

1. Downloaded the 2148 version with 2 dll's (ICSharpCode.SharpZipLib.dll and MessageBoxExLib.dll) and replaced these files.

2. Deleted autoupdate.xml file.

After that autoupdate worked great.

[Carpo]

is there any chance the bitrate calc could be sorted out in newer versions of megi - for example the ones from x264.nl or poss someone could point us in the direction of a standalone calc till its sorted ?

[bkman]

Three things:

1.) Where did the DAR setting go?
2.) What does the "auto increase volume" option do? Normalise to 100%?
3.) Why not have the option of DRC in AC3 input with nicaudio?

1. ) To the video preview window -- if it doesn't automatically open when you load a script, try double-clicking on the input filename to open the preview. It makes more sense to have the DAR tied into the script as opposed to the codec settings.
2. ) and 3. ) you'll have to wait for dimzon's response.

im currently having problems using megui, no matter what profile i use to encode the video rendering rate is always about 1fps, does anyone know what could be causing the problem?

[Sharktooth]

too much filters?

[rhys87]

DGDecode_mpeg2source("C:\Program Files\WebScheduler\capture\(2006-05-20 15-25) Video (02).d2v")
edeintted = last.AssumeTFF().SeparateFields().SelectEven().EEDI2(field=-1)
TDeint(order=1,edeint=edeintted)
#crop
LanczosResize(512,288) # Lanczos (Sharp)
#denoise

[Sharktooth]

what are your system specs? (CPU, RAM, etc...)

[rhys87]

athlon64 3200+, 1gb generic ram, 160gb hard drive

[Sharktooth]

uhm, you should get much higher speeds with that configuration.
are you sure speed doesnt change if you select "lighter" profiles?

[rhys87]

yep just tried 1passmaxspeed and got .78fps. I also tried not deinterlacing and got the same.
