MeGUI: General Questions and Troubleshooting Thread

[b66pak]

i order to avoid the random (rare) .mp4 "bad public atom error" i tried to encode to raw .h264 but after i select "autoencode" and add the audio and select the .mp4 container the queue is like:

video>.mp4
video.mp4+audio.m4a>muxed.mp4

it should be like:

video>.264
video.264+audio.m4a>muxed.mp4


do you plan to fix this?

(lots of text removed, read the above0

OK, I personally think are over thinking this.

Yes, the active picture area of 720x480, or 720x576, is 704 (not 702).

When creating a MKV H.264 video file, with whatever audio you want, you want to use these settings:

For anamorphic widescreen: NTSC 16:9 or PAL 16:9
For 4:3: NTSC 4:3 or PAL 4:3
Crop to 704x480 or 704x576
Clever anamorphic widescreen checked. if anamorphic 16:9 source

Next page:
Interlaced
Top field
deinterlace

It actually doesn't hurt to leave the file at 720, without cropping. It is only 8 pixels on each side. That equates to 12 pixels on each side for display on a 1280 wide display. Yes, it does mean a minor error in the 16:9 display, but it is extremely minor.

Don't get caught up in figuring out aspect ratios, especially non-square pixel ratios. It isn't worth it. Analog TVs haven't delivered perfect 4:3 since they day the first electron beam scanned a round tube. You are never going to achieve perfect 16:9 from 4:3 source material. Don't try. No one will even notice.

@Mr Video.

Hi. Thanks for your advice. I take it on board.

I understand my thinking was more academic than practical I just wanted to know 'why' rather than shrugging my shoulders and ticking the box. I have a better understanding now so all is good.

:thanks:

[MrVideo]

I have a better understanding now so all is good.

You could almost make your head explode if you dig too deep into this. There is a lot of misconception regarding what the square area is of analog video, let alone what happens when converted to digital.

There is a very good website that deals in this and I think I have a link to it on my main webpage.

There are a lot of files that are built by the torrent people that are not true 16:9. They take a 16:9 HD TV show and make 640x352 files. Sorry, but true 16:9 is 640x360. They are making 1.82 files, instead of 1.78 files. Because the size of the file dimensions are so small, the error percentage is a lot higher. Of course they could crop some of the original image in order to keep the correct aspect ratio, but doing either is wrong, in my book.

Even though many tools will complain when encoding 640x360 H.264 files, MPEG-4 doesn't have the mod16 requirement, so true 16:9 files can be made. But, they don't. I make true 640x360 files of promos for my website all the time.

BTW, in case you ever try it, MeGUI won't let you take a true 16:9 HD file (1080i or 720p) and make an anamorphic widescreen 720x576 or 720x480 MKV file, with the smart anamorphic option set. Once you've set all the options, even though the resize value is wrong (you gotta set it wrong in order get the smart flag on). you manually edit the avisynth line before saving it for MeGUI processing. Make sure that you manually set the aspect ratio to 1.78 (it isn't 1.778 as sharktooth likes to set it, as the television industry uses 1.78). I don't know why 1.78 isn't automatically set when HD files are used.

By creating anamorphic widescreen files, you reduce the file size because you aren't creating 1024x576, or 853x480 files.

Any further questions, be sure to ask, as someone here will have an answer.

[Nightshiver]

Ugh, I seem to be having trouble with mencoder again. x264 is once again crashing even though I've used both of the most recently updates mencoders, which should have worked.

[ricky man]

i have error msg: Directshowsource: Renderfile, filter manager wont talk to me.

does anyone know what is that mean? and how can i fix this problem.

[Sharktooth]

means it's not a megui problem but a general directshow problem.
the directshow filter(s) used for the input file are "locked" to a certain application or just do not work.
how to fix: use graphedit/graphstudio to create a graph of the filters, identify the "broken" ones and de-register them (using regsvr32 /u filterfilename.ext) and eventually install an appropriate filter that replaces the functionality of the broken/proprietary one.

[Nightshiver]

This is pretty ridiculous. I've gone through the first 5 builds now with none of them working. I just re-formatted my hdd so this problem shouldn't even exist. Is there a way to get in touch with whoever is updating the mencoder builds?

[Kurtnoise]

that's pretty ridiculous how you try to make bugs reports...:rolleyes:

:stupid:

[Nightshiver]

And calling me stupid solves the problem? No one said I was trying to make a bug report. It's been like that for months, if you've checked on when I first stated I had this problem. You post is also useless in that it simply calls me "ridiculous" instead of useful information. That, is pretty ridiculous. And if I was making a bug report, what the hell else would I say? Seeing as how you don't have this problem, you don't realize how depressing it is to continually try different builds hoping that it will work only to see that it doesn't. It's also curious as to how I'm the only one (that I've seen) that has this problem. The standard error stream give's nothing informative. The most recent builds of mencoder should have worked, but I don't know why they haven't.

[jeffy]

@Nightshiver: still the same source as here?
http://forum.doom9.org/showthread.php?p=1190220#post1190220

Might this be the cause (if still true)?

[Nightshiver]

I'm not using huffy/pre-rendering right now.

[Codex0nz]

Latest version of megui (1010) has changed preview in avs script :/ now you can't cycle through video as if its playing, and for some reason ive found it harder to spot things in it (eg i had to use another program to get a single frame of my source to discover it was field blended as when in preview on megui it just looked like it was just two blended frames (eg, 2 layers 50% opacity together)

Don't know whats changed or if it was on purpose but is there any way to change it back :S

[ricky man]

i want to know if MeGui can make DVD to 1080p or not? if not , what programs can make it?

[Sharktooth]

DVD standard does not support 1080p.

[MrVideo]

i want to know if MeGui can make DVD to 1080p or not? if not , what programs can make it?

DVDs are standard def only: NTSC or PAL, 4:3 or anamorphic widescreen 16:9.

You want anything higher than 480i/576i, you'll have to create Blu-ray, which handles 720p/1080i/1080p.

[MrVideo]

I'm not using huffy/pre-rendering right now.

When you just complain and say something doesn't work and to "fix it" is not helpful. It just tends to piss others off.

I use MeGUI out-of-the-box and have no problem making 720p and 1080i MKV files.

So, you need to list your operating system, and service paks. You need to provide examples of the command lines that MeGUI is using to do the encoding. You need to provide the avisynth script.

No one here has a crystal ball where they can see what you are doing. You have to provide details.

Hi, thanks for this great tool.

I'm getting a error trying to encode a movie with megui for my psp.

hello,

if i want to put megui into 64bit windows, what encoder and programs i need to run it?

[Kurtnoise]

if i want to put megui into 64bit windows, what encoder and programs i need to run it?
all x86 encoders provided by the megui updater should run out the box on x64...

Try to change your folder pathname into something more simple (i.e D:\DVD Completos Para Gravar\MainMovie\DVD_VOLUME)...

[Snowknight26]

Any word on the supposedly fixed DTS bitrate issue?

[Dreassica]

SOmehow Megui doesn't want to update the core anymore.
It tells me it successfully downloaded the update and it needs a restart.
But when it does, it still at teh old version and asks me to update again.

[SacredCultivator]

Okay this might be a dumb question but for teh "Threads" would it be wise ot just set at "0 (Auto)" or to specify? Example being if I'm using a Core 2 Duo, I'd set it to "2" correct?
{Trying to maximize my FPS encoding on my videos's as the max I hit is at 4fps, H264 encoding at 1280x720 res}

More or less would there be any other settings that might need to be adjusted if using Core 2 Duo opposed to let's say a Single Core?

Thanks.

---
EDIT:
And sorry if I misheard from a friend or not but... does meGUI support Quad Core? (Better benefit over Duo?{I assume yes})

[Kurtnoise]

yes, it supports quadcore...and let set the thread # to auto if you're using x264.

[SacredCultivator]

Thanks, dangit, I shoulda bought a Quad Core when I bought my System (Only got it a few days ago), oh well, if I may ask.. what other components affect the Encoding Time (If not including Filters)

[b66pak]

i order to avoid the random (rare) .mp4 "bad public atom error" i tried to encode to raw .h264 but after i select "autoencode" and add the audio and select the .mp4 container the queue is like:

video>.mp4
video.mp4+audio.m4a>muxed.mp4

it should be like:

video>.264
video.264+audio.m4a>muxed.mp4


do you plan to fix this?
_

still not fixed...
_

[Sharktooth]

we dont fix bugs for other softwares.
the problem of bad public atom error is in mp4box.
if you found a workaround using raw avc then use manual encoding.

[Kurtnoise]

that's not a mp4box bug for sure.

more a file not supported by a player beginning by "quick" and ending by "time"...:p So, it's not my 1st priority you know.

[Sharktooth]

oh... then we wont fix CrapTime(tm).

Hi, i've just updated megui's core and x264, and it seems that when i open a mkv file with XVID and AAC, aero stops working and vista turns to basic. As soon as i quit megui, everything's back to normal. Any ideas? Weird bug, don't know if it has to do with the update though.

[Tae]

Just FYI on interface problem in Vista 64. I know you don't support it, but I have lost Gui buttons in the past but was able to get around it. This one is a killer...

http://img.photobucket.com/albums/v385/tkilmer/meguiinterfaceerror.jpg

I lost the Avisynth save button before, but was about to work around. Have not had the Aspect ratio button either. Not sure why this is happening, just thought you should know. I went back to core 0.3.0.3004 to get the DV2 Creator fixed, so it was lost with a change since then.

Just an update, the buttons are back. I noticed it after I updated tonight to the latest stable release.

Thanks

which filters/decoders do you have installed ?

[Grossmeister]

When I open a video file (PAL) using
FFMS2_FFVideoSource(source="C:\temp\video\Assist_cap0001.avi", seekmode=1)
And pass it to MeGUI, MeGUI tells me that video is in I420 format, and proposes to add ConvertToYV12() at the end, and after that it tells that video is still in I420, not in YV12 (look at attached image). Nothing changes if I add ConvertToYV12() to .avs script myself.

Then I used
WriteFile("D:\convert\AvsP\info.txt","IsRGB32")
WriteFile("D:\convert\AvsP\info.txt","IsYUY2")
WriteFile("D:\convert\AvsP\info.txt","IsYV12")
code to check the colorformat after FFMS2_FFVideoSource() call and I received "true" for IsYV12.
So, I can't understand, why MeGUI keeps telling me that the input format is no YV12.

After that I tried AVISource and it worked well. But, there is a question: in AViSource help (http://avisynth.org/AviSource) it is written that by default pixel_type = YV12, and also it written that sometimes it is better to open video in same (video's) colorformat.

I'm using x264 as encoder, what should I do:
1. Use FFMS2_FFVideoSource(). Then what to do with warning from MeGUI?
2. Use AVISource(pixel_type="source_format") and then ConvertToYV12(). Then how to know about what is video file colorformat.
3. Use AVISource() with default pixel_type = "YV12"?

Thanks.

[Kurtnoise]

can't see the picture yet but I'd say #2...

[Grossmeister]

can't see the picture yet but I'd say #2...
Hmm, it (the picture) is still pending approval. Here what is writen there:
Your AviSynth clip has the following problem:
AviSynth clip is in I420 not in YV12, even though ConvertToYV12() has been appended.
Continue anyway?

And if #2, then how can I check original file colorformat? I couldn't find such information in MediaInfo.
